The central potion of the welcome screen welcomes you to Mathematica and introduces one of the new
features in the latest version of the software. There are also links to documentation, support, and
demonstrations.
On the left side of the welcome screen are icons for creating new documents or opening existing docu-
ments. To open an existing file that is not in the list of recent documents, perhaps a notebook that you
created or one of the chapters of this manual, you click on “Open...” and a standard file selection
dialog will appear that allows to you select the file you want. Otherwise, to create a new document to
work in, simply click on “Notebook” under “Create New...” at the top of the left panel.
Mathematica Notebooks
This Introduction, and in fact all the chapters of this manual, were created as Mathematica Notebooks.
A Mathematica Notebook can be thought of like a document in a word processing program. You can
type text, change the font, insert images, and use other typical word processing tasks. But you also
have a powerful mathematical engine at your fingertips.
In a Mathematica Notebook, everything you enter and all of the results of computations are stored in
cells. We will mention three kinds of cells: input, output, and text.
To create a new cell, use the mouse or keyboard arrow keys to the bottom of a Notebook or between
two existing cells. You should see a faint horizontal line across the entire window with a plus sign
hanging below the line at the left margin: .
By clicking on the plus symbol, Mathematica will present you with a menu of the most common cell
types. To create an input cell, click on “Mathematica input”, or click on “Plain text” to create a text
cell.
Alternately, you can press the command key (the cloverleaf on a Mac) and the number 7 (·+7 or
Ì+7) to create a text cell. For an input cell, press ·+9 or Ì+9.
Finally, if you simply start typing, Mathematica will automatically create a new cell for you. The kind
of cell depends on options set in the software and on the particular Notebook’s style, but for a brand
new Notebook with the default options, an input cell should be created if you start typing with the
cursor not in an existing cell.
