Or

Subtraction is operation of removing objects from a collection. The result of a subtraction is called a difference.

Take it, take it, take it away.

This number is not here to stay.

When you subtract, I
must

Confess,

You will always go back home with

Less!

##### Facts about subtraction

1) When 1 is subtracted from a number,

We get the previous number.

Example:  7-1=6

2) When we subtract a number from itself,

The difference is always zero.

Example: 7-7=0

3) When we subtract zero from a number then,

Difference is the number itself.

Example: 7-0=7

4) Order of number affects the subtraction

Example: 3-2 is not equal to 2-3

##### Relation between Addition and     Subtraction

Addition and Subtraction are
inverse relations.

That means when two numbers are
added, we get another number called             sum.

Now , if we subtract any one
number from this sum,

We get the other number

Example:

6   + 4  =  10                      10  – 4  =  6

4 +  6  = 10                       10  – 6  =  4
