In subtraction, we need two numbers. If first number is greater than the 2nd then we can subtract easily, such subtraction is known as subtraction of a number without borrowing.

Another word for subtraction is minus ( -) and we put this sign between the two numbers.

For lower grade math the answer of minus is always less than the first number and greater than the 2nd number.

How many flowers are there ? If there are 2 blue flower then how many are red flowers?

Total flowers = 7

Blue flowers = 2

So, if we remove blue flowers from the total we will get red flowers.

Removing means subtraction.

7 – 2 = 5

Red flowers = 5

9 – 1 = 8

8 – 2 = 6

7 - 1 = 6

4 - 4 = 0

Another method of solving subtraction is below but this method is for only single digit.

8 0 0 0 0 0 0 0 0 - 5 Cut 5 circles 8 0 0 0 ∅ ∅ ∅ ∅ ∅ - 5 Count the number of circles remain. 8 - 5 ------ 3 -----> answer |

5 8 9 - 2 - 4 - 3 ------ -------- -------- 3 4 6 |
