Number line

A line on which numbers are marked is called 'The number line '.

0 1 2 3 4 5 6 7 8 9 10 11 12

Comparision of numbers

We can compare the numbers by saying which is greater and which is smaller.

Ex : 5, 2

5 dots are there in the left set and 2 dots are there in the right set.

5 is greater than 2. The symbol > denotes 'Greater than'.

5> 2 5 is greater than 2


Ex : 3, 6 29

3 dots are there in the left set and 6 dots are there in the right set.

3 is lessr than 6. The symbol < denotes 'Less than'.

3 < 6 3 is less than 6

Ex : 4, 4

4 dots are there in the left set and 4 dots are there in the right set.

4 is equal to 4 The symbol = denotes 'Equal to'.

4 = 4 4 is equal to 4

A natural number containing more digits represents a greater number

Ex : 983, 34
983 has 3 digits ( 9,8,3) and 34 has 2 digits (3,4)
So 983 > 34
983 is greater than 34

If two numerals contain the same number of digits, we compare them by


their left most digits.
If the left most digits are same in a numeral, we compare them by their
next digits from the left and so on.

Ex : 784, 673
These two numerals contain the same number of digits (3 digits).
The left most digit in 784 is 7
The left most digit in 673 is 6
7 > 6. So 784 > 673
Ex : 784, 763 30

These two numerals contain the same number of digits (3 digits).


The left most digit in 784 is 7
The left most digit in 763 is also 7
The next left most digit in 784 is 8
The next left most digit in 763 is 6
8 > 6. So 784 > 763

Ex : 784, 783
These two numerals contain the same number of digits (3 digits).
The left most digit in 784 is 7
The left most digit in 783 is also 7
The next left most digit in 784 is 8
The next left most digit in 783 is also 8
The next left most digit in 784 is 4
The next left most digit in 783 is 3
4 > 3. So 784 > 783

Observe the Number line

0 1 2 3 4 5 6 7 8 9 10 11 12

On a number line, every number is lesser than the numbers on the right
and is greater than the numbers on the left.

Ex : 5 < 6 5> 4
5 is less than 6 5 is greater than 4

Successor

The number that comes just after a particular number is called its 'Successor'.
By adding 1 to any natural number we get its 'Successor'

Ex : 36 + 1 = 37 The successor of 36 is 37
Every number is less than its successor. 31

Ex : 7 < 8
The successor of 7 is 8. 7 is less than 8

Predecessor

The number that comes just before a particular number is called its
'Predecessor'.
By subtracting 1 from any natural number we get its 'Predecessor'

Ex : 42 - 1 = 41 The predecessor of 42 is 41

Every number is greater than its predecessor.


Ex : 7 < 8
The predesessor of 8 is 7. 8 is greater than 7

In whole numbers, zero (0) has no predecessor.


But the successor of zero (0) is 1

Every number lies between its successor and predecessor

Ex : 2 > 3 > 4
Here the successor of 3 is 4 and the predesessor of 3 is 2
3 lies between 2 and 4

Ascending order

9 < 10 < 11 < 12 < 13 < 14 < 15


Observe the order. These numbers are in the increasing order from smaller
to bigger.

If the numbers are in the order from smaller to bigger, it is called 'The Ascending
order' of numbers
Descending order 32

15> 14 >13 > 12 >11 < 10 < 9

Observe the order. These numbers are in the decreasing order from bigger
to smaller

If the numbers are in the order from bigger to smaller, it is called


'The Descending order' of numbers
