Solved Questions on Subtraction

1. What is the difference between 18 and 6?

a) 12

c) 10
d) 7

Answer: a) 12

Explanation: We need to find the difference between 18 and 6. For performing subtraction in columns, place the greater value at the top and the smaller value below it.
18 - 6 = 12
8 - 6 = 2 and 1 - 0 = 1 Hence, 18 - 6 = 12.

3. Subtract 14 from 45.

a) 15
b) 18
c) 21
d) 31

Answer: d) 31

Explanation: Using the non-regrouping method, we first start from the right side and subtract 4 from 5.

We subtract 1 from 4.
4 - 1 = 3
The difference comes out to be 3.

Hence, the answer is 31.
