must

Confess,

You will always go back home with

               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
