Cell basics
 basic ways you can work with cells and cell content in
 Excel to be able to use it to calculate, analyze, and
 organize data. In this lesson, you will learn how to
 select cells, insert content, and delete cells and
 cell content. You will also learn how to cut, copy,
 and paste cells; drag and drop cells; and fill cells
 using the fill handle.
Introduction to cells and cell content
 Cells are the basic building blocks of a worksheet.
  Cells can contain a variety of content such as text,
  formatting attributes, formulas, and functions. To
  work with cells, you'll need to know how to select
  them, insert content, and delete cells and cell
  content.
The cell
 Each rectangle in a worksheet is called a cell. A cell is
  the intersection of a row and a column.
 Each cell has a name, or a cell address based on
  which column and row it intersects. The cell
  address of a selected cell appears in the Name box.
 You can also select multiple cells at the same time. A
  group of cells is known as a cell range. Rather than a
  single cell address, you will refer to a cell range using
  the cell addresses of the first and last cells in the cell
  range, separated by a colon. For example A2:A5
 If the columns in your spreadsheet are labeled with
  numbers instead of letters, you'll need to change the
  default reference style for Excel.
To select a cell:
 Click on a cell to select it. When a cell is selected, you
  will notice that the borders of the cell appear bold
  and the column heading and row heading of the
  cell are highlighted.
 Release your mouse. The cell will stay selected until
  you click on another cell in the worksheet.
 You can also navigate through your worksheet and
  select a cell by using the arrow keys on your keyboard.
To select multiple cells:
 Click and drag your mouse until all of the adjoining
  cells you want are highlighted.
 Release your mouse. The cells will stay selected until
  you click on another cell in the worksheet.
Cell content
 Each cell can contain its own text, formatting, comments,
  formulas, and functions.
Text
 Cells can contain letters, numbers, and dates. alng right
Formatting attributes
 Cells can contain formatting attributes that change the way
  letters, numbers, and dates are displayed. For example,
  dates can be formatted as MM/DD/YYYY or M/D/YYYY.
Comments
 Cells can contain comments from multiple reviewers.
Formulas and functions
 Cells can contain formulas and functions that calculate cell
  values. For example, 1.SUM(cell 1, cell 2...,
  cell1=cell4+cell5 are a formulas that can add the values in
  multiple cells.
To insert content:
 Click on a cell to select it.
 Enter content into the selected cell using your keyboard.
  The content appears in the cell and in the formula bar.
  You also can enter or edit cell content from the formula bar.
To delete content within cells:
 Select the cells containing content you want to delete.
 Click the Clear command on the Ribbon. A dialog box
  will appear.
 Select Clear Contents.
 You can also use your keyboard's Backspace key to delete
  content from a single cell or the Delete key to delete
  content from multiple cells.
To delete cells:
 Select the cells you want to delete.
 Choose the Delete command from the Ribbon.
 There is an important difference between deleting
  the content of a cell and deleting the cell itself. If
  you delete the cell, by default the cells underneath it
  will shift up and replace the deleted cell.
copy and paste cell content:
 Select the cells you wish to copy.
 Click the Copy command. The border of the selected cells
  will change appearance.
 Select the cell or cells where you want to paste the content.
 Click the Paste command. The copied content will be
  entered into the highlighted cells.
To cut and paste cell content:
 Select the cells you wish to cut.
 Click the Cut command. The border of the selected cells
  will change appearance.
 Select the cells where you want to paste the content.
 Click the Paste command. The cut content will be removed
  from the original cells and entered into the highlighted
  cells.
To access more paste options:
 There are more Paste options you can access from the
  drop-down menu on the Paste command. These
  options may be convenient to advanced users who are
  working with cells that contain formulas or
  formatting.
To access formatting commands by right-clicking:
 Select the cells you want to format.
 Right-click on the selected cells. A dialog box will
  appear where you can easily access many commands
  that are on the Ribbon.
To drag and drop cells:
 Select the cells you want to move.
 Position your mouse on one of the outside edges of the selected
  cells. The mouse changes from a white cross to a black cross
  with 4 arrows.
 Click and drag the cells to the new location.
 Release your mouse, and the cells will be dropped there.
To use the fill handle to fill cells:
 Select the cell or cells containing the content you want to use.
  You can fill cell content either vertically or horizontally.
 Position your mouse over the fill handle so the white cross
  becomes a black cross .
 Click and drag the fill handle until all of the cells you want to
  fill are highlighted.
 Release the mouse, and your cells will be filled.
MODIFYING ROWS COLUMS AND
CELLS
 When you open a new, blank workbook, the cells are
 set to a default size. You have the ability to modify
 cells, as well as to insert and delete columns, rows, and
 cells as needed. In this lesson, you will learn how to
 change row height and column width, insert and
 delete rows and columns, wrap text in a cell, and
 merge cells.
Working with columns, rows, and cells
 By default, every row and column of a new workbook is
  always set to the same height and width. Excel allows you
  to modify column width and row height in many different
  ways.
To modify column width:
 Position your mouse over the column line in the column
  heading so the white cross becomes a double arrow .
 Click and drag the column to the right to increase the
  column width or to the left to decrease the column width.
 Release the mouse. The column width will be changed in
  your spreadsheet.
 If you see pound signs (#######) in a cell, it means that
  the column is not wide enough to display the cell content.
  Simply increase the column width to show the cell
  content.
To set column width with a specific measurement:
 Select the columns you want to modify.
 Click the Format command on the Home tab. The
  format drop-down menu appears.
 Select Column Width.
 The Column Width dialog box appears. Enter a
  specific measurement.
 Click OK. The width of each selected column will be
  changed in your worksheet.
 Select AutoFit Column Width from the format drop-
  down menu, and Excel will automatically adjust each
  selected column so all of the text will fit.
To modify the row height:
 Position the cursor over the row line so the white
  cross becomes a double arrow .
 Click and drag the row downward to increase the
  row height or upward decrease the row height.
 Release the mouse. The height of each selected
  row will be changed in your worksheet.
To set row height with a specific measurement:
 Select the rows you want to modify.
 Click the Format command on the Home tab.
  The format drop-down menu appears.
 Select Row Height.
 The Row Height dialog box appears. Enter a
  specific measurement.
 Click OK. The selected rows heights will be
  changed in your spreadsheet.
 Select AutoFit Row Height from the format drop-
  down menu, and Excel will automatically adjust
  each selected row so all of the text will fit.
To insert rows:
 Select the row below where you want the new row to
  appear.
 Click the Insert command on the Home tab.
 The new row appears in your worksheet.
 When inserting new rows, columns, or cells, you will see
  the Insert Options button by the inserted cells. This
  button allows you to choose how Excel formats them. By
  default, Excel formats inserted rows with the same
  formatting as the cells in the row above them. To access
  more options, hover your mouse over the Insert Options
  button and click the drop-down arrow that appears.
To insert columns:
 Select the column to the right of where you want the new
  column to appear. For example, if you want to insert a
  column between A and B, select column B.
 Click the Insert command on the Home tab.
 The new column appears in your worksheet.
 By default, Excel formats inserted columns with the same
  formatting as the column to the left of them. To access
  more options, hover your mouse over the Insert Options
  button and click the drop-down arrow that appears.
 When inserting rows and columns, make sure you select
  the row or column by clicking on its heading so all the cells
  in that row or column are selected. If you select just a cell in
  the row or column, then only a new cell will be inserted.
To delete rows:
 Select the rows you want to delete.
 Click the Delete command on the Home tab.
 The rows are deleted from your worksheet.
To delete columns:
 Select the columns you want to delete.
 Click the Delete command on the Home tab.
 The columns are deleted from your worksheet.
Creating simple formulas
 Excel can be used to calculate numerical information.
 In this lesson, you will learn how to create simple
 formulas in Excel to add, subtract, multiply, and
 divide values in a workbook. Also, you will learn the
 various ways you can use cell references to make
 working with formulas easier and more efficient.
Simple formulas
 A formula is an equation that performs a calculation.
  Like a calculator, Excel can execute formulas that add,
  subtract, multiply, and divide.
 One of the most useful features of Excel is its ability to
  calculate using a cell address to represent the value in a
  cell. This is called using a cell reference.
 In order to maximize the capabilities of Excel, it is
  important to understand how to create simple
  formulas and use cell references.
Creating simple formulas
 Excel uses standard operators for equations, such as a
  plus sign for addition (+), minus sign for subtraction
  (-), asterisk for multiplication (*), forward slash for
  division (/), and caret (^) for exponents.
 The key thing to remember when writing formulas for
  Excel is that all formulas must begin with an equals
  sign (=). This is because the cell contains, or is equal
  to, the formula and its value.
To create a simple formula in Excel:
 Select the cell where the answer will appear (B4, for
  example).
 Type the equals sign (=).
 Type in the formula you want Excel to calculate. For
  example, "75/250".
 Press Enter. The formula will be calculated, and the
  value will be displayed in the cell.
 If the result of a formula is too large to be displayed in
  a cell, it may appear as pound signs (#######)
  instead of a value. This means that the column is not
  wide enough to display the cell content.
  Simply increase the column width to show the cell
  content.
Creating formulas with cell references
 When a formula contains a cell address, it is called a
  cell reference. Creating a formula with cell references
  is useful because you can update data in your
  worksheet without having to rewrite the values in the
  formula.
To create a formula using cell references:
 Select the cell where the answer will appear (B3, for
  example).
 Type the equals sign (=).
 Type the cell address that contains the first number in
  the equation (B1, for example).
 Type the operator you need for your formula. For
    example, type the addition sign (+).
   Type the cell address that contains the second number
    in the equation (B2, for example).
   Press Enter. The formula will be calculated, and the
    value will be displayed in the cell.
   If you change a value in either B1 or B2, the total will
    automatically recalculate.
   Nb:it's up to you to check all of your formulas.
To create a formula using the point-and-click
method:
 Select the cell where the answer will appear (B4, for
  example).
 Type the equals sign (=).
 Click on the first cell to be included in the formula
  (A3, for example).
 Type the operator you need for your formula. For
  example, type the multiplication sign (*).
 Click on the next cell in the formula (B3, for
  example).
 Press Enter. The formula will be calculated, and the
  value will be displayed in the cell.
To edit a formula:
 Click on the cell you want to edit.
 Insert the cursor in the formula bar, and edit the
  formula as desired. You can also double-click the cell
  to view and edit the formula directly from the cell.
 When finished, press Enter or select the Enter
  command .
 The new value will be displayed in the cell.
 If you change your mind, use the Cancel command in
  the formula bar to avoid accidentally making changes
  to your formula.
/////Creating complex formulas
 Excel is a spreadsheet application that can help
  you calculate and analyze numerical information
  for household budgets, company finances,
  inventory, and more. To do this, you need to
  understand complex formulas.
 We will learn how to write complex formulas in
  Excel following the order of operations. You will
  also learn about relative and absolute cell
  references and how to copy and fill formulas
  containing cell references.
Complex formulas
 Simple formulas have one mathematical operation, such as
  5+5. Complex formulas have more than one
  mathematical operation, such as 5+5-2*(3/2). When there
  is more than one operation in a formula, the order of
  operations tells us which operation to calculate first. In
  order to use Excel to calculate complex formulas, you will
  need to understand the order of operations.
Order of operations
 Excel calculates formulas based on the following order of
  operations:
 Operations enclosed in parentheses
 Exponential calculations (to the power of)
 Multiplication and division, whichever comes first
 Addition and subtraction, whichever comes first
To create a complex formula using the order of
operations:
 In this example, we will use cell references in
  addition to actual values to create a complex
  formula that will add tax to the salary.
 Click the cell where you want the formula result to
  appear (for example, F11).
 Type the equals sign (=).
 Type an open parenthesis, then click on the cell
  that contains the first value you want in the
  formula (for example, F4).
 Type the first mathematical operator (for
  example, the addition sign).
 Click on the cell that contains the second value
  you want in the formula (for example, F5), then
  type a closed parenthesis.
 Type the next mathematical operator (for
  example, the multiplication sign).
 Type the next value in the formula (then click on
  the cell that contains the next value you want in
  the formula).
 Click Enter to calculate your formula.
 . You can see from this example that it is important to
 enter complex formulas with the correct order of
 operations. Otherwise, Excel will not calculate the
 results accurately.
Working with cell references
Working with cell references
 In order to maintain accurate formulas, it is necessary to
  understand how cell references respond when you copy or
  fill them to new cells in the worksheet.
 Excel will interpret cell references as either relative or
  absolute. By default, cell references are relative
  references. When copied or filled, they change based on
  the relative position of rows and columns. If you copy a
  formula (=A1+B1) into row 2, the formula will change to
  become (=A2+B2).
 Absolute references, on the other hand, do not change
  when they are copied or filled and are used when you want
  the values to stay the same.
Relative references
 Relative references can save you time when you are
  repeating the same kind of calculation across multiple
  rows or columns.
 In the following example, we are creating a formula
  with cell references in row 4 to calculate the total cost
  of the electric bill and water bill for each month
  (B4=B2+B3). For the upcoming months, we want to use
  the same formula with relative references (C2+C3,
  D2+D3, E2+E3, etc.) For convenience, we can copy the
  formula in B4 into the rest of row 4, and Excel will
  calculate the value of the bills for those months using
  relative references.
To create and copy a formula using relative references:
 Select the first cell where you want to enter the formula (for
  example, B4).
 Enter the formula to calculate the value you want (for
  example, add B2+B3).
 Press Enter. The formula will be calculated.
 Select the cell you want to copy (for example, B4), then
  click on the Copy command from the Home tab.
 Select the cells where you want to paste the formula, then
  click on the Paste command from the Home tab. (You can
  also drag the fill handle to fill cells.)
 Your formula is copied to the selected cells as a relative
  reference (C4=C2+C3, D4=D2+D3, E4=E2+E3, etc.), and the
  values are calculated.
Absolute references
 There may be times when you do not want a cell
  reference to change when copying or filling cells. You
  can use an absolute reference to keep a row and/or
  column constant in the formula.
 An absolute reference is designated in the formula by
  the addition of a dollar sign ($). It can precede the
  column reference, the row reference, or both.
 We will calculate the sales tax for a list of products
  with varying prices. We will use an absolute reference
  for the sales tax ($B$1) because we do not want it to
  change as we are copying the formula down the
  column of varying prices.
To create and copy a formula using an absolute
reference:
 Select the first cell where you want to enter the
  formula (for example, C4).
 Click on the cell that contains the first value you want
  in the formula (for example, B4).
 Type the first mathematical operator (for example,
  the multiplication sign).
 Type the dollar sign ($), then enter the column
  letter of the cell you are making an absolute reference
  to (for example, B).
 Type the dollar sign ($), then enter the row number
  of the same cell you are making an absolute reference
  to.
 Press Enter to calculate the formula.
 Select the cell you want to copy (for example, C4), then
  click the Copy command from the Home tab.
 Select the cells where you want to paste the formula,
  then click the Paste command from the Home tab.
  (You can also drag the fill handle to fill cells.)
 Your formula is copied to the selected cells using the
  absolute reference (C5=B5*$B$1, C6=B6*$B$1, etc.), and
  your values are calculated.
 When writing a formula, you can press the F4 key on
  your keyboard to switch between relative and absolute
  cell references. This is an easy way to quickly insert an
  absolute reference.//////
WORKING WITH CHARTS
 A chart is a tool you can use in Excel to communicate
 your data graphically. Charts allow your audience to
 see the meaning behind the numbers, and they
 make showing comparisons and trends a lot easier.
 In this lesson, you will learn how to insert charts and
 modify them so they communicate information
 effectively.
Charts
 Excel workbooks can contain a lot of data, and that
  data can often be difficult to interpret. For example,
  where are the highest and lowest values? Are the
  numbers increasing or decreasing?
 The answers to questions like these can become much
  clearer when the data is represented as a chart. Excel
  has many different types of charts, so you can choose
  one that most effectively represents the data.
Types of charts
 Excel has a variety of chart types, each with its own
  advantages.
 (Line, Bar, Column, Pie, Area, Surface)
 Line charts are ideal for showing trends.
 Bar charts work just like Column charts, but they use
  horizontal bars instead of vertical bars.
 Column charts use vertical bars to represent data.
  They can work with many different types of data, but
  they're most frequently used for comparing
  information.
 Pie charts make it easy to compare proportions. Each
  value is shown as a slice of the pie, so it's easy to see
  which values make up the percentage of a whole.
 Area charts are similar to line charts, except the areas under
  the lines are filled in.
 Surface charts allow you to display data across a 3D
  landscape. They work best with large data sets, allowing
  you to see a variety of information at the same time.
Parts of a chart
 Title,
 Dataseries The data series consists of the related data
  points in a chart. If there are multiple data series in the
  chart, each one will have a different color or style. Pie
  charts can only have one data series.
 In this example, the green columns represent the
  Romance data series.
 The legend identifies which data series each color on
  the chart represents. For many charts it is crucial, but
  for some charts it may not be necessary and can be
  deleted.
 The vertical axis (also known as the y axis) is the
  vertical part of the chart.
 The horizontal axis (also known as the x axis) is the
  horizontal part of the chart. In this example, the
  horizontal axis identifies the categories in the chart,
  so it is also called the category axis. However, in a bar
  chart, the vertical axis would be the category axis.
To create a chart:
 Select the cells you want to chart, including the
  column titles and row labels. These cells will be the
  source data for the chart.
 Click the Insert tab.
 In the Charts group, select the desired chart category
  (Column, for example).
 Select the desired chart type from the drop-down
  menu (Clustered Column, for example).
 The chart will appear in the worksheet.
Chart tools
 Once you insert a chart, a set of Chart Tools arranged
  into three tabs will appear on the Ribbon. These are
  only visible when the chart is selected. You can use
  these three tabs to modify your chart.
To change the chart type:
 From the Design tab, click the Change Chart Type
  command. A dialog box appears.
 Select the desired chart type, then click OK.
To switch row and column data:
 Sometimes when you create a chart, the data may not
  be grouped the way you want it to be.
 Select the chart.
 From the Design tab, select the Switch Row/Column
  command.
 The chart will then readjust.
To change the chart layout:
 Select the Design tab.
 Click the More drop-down arrow in the Chart
  Layouts group to see all of the available layouts.
 Select the desired layout.
 The chart will update to reflect the new layout.
 Some layouts include chart titles, axes, or legend
  labels. To change them, just place the insertion
  point in the text and begin typing.
To change the chart style:
 Select the Design tab.
 Click the More drop-down arrow in the Chart Styles
  group to see all of the available styles.
 Select the desired style.
 The chart will update to reflect the new style.
To move the chart to a different worksheet:
 Select the Design tab.
 Click the Move Chart command. A dialog box
  appears. The current location of the chart is selected.
 Select the desired location for the chart (i.e., choose an
  existing worksheet, or select New Sheet and name it).
 Click OK. The chart will appear in the new location.
