Question

2. Write down the four main math operations and the inverse operation for each one.

Answer 1

The main math operations

1. Addition

For example,

8 = 5 + 3

Its inverse operation is substraction:

8 - 5 = 3

2. Substraction

For example,

4 - 1 = 3

Its inverse operation is addition:

4 = 3 + 1

3. Multiplication

For example,

12 = 4 x 3

Its inverse operation is division:

12 ÷ 4 = 3

4. Division

For example,

20 ÷ 5 = 4

Its inverse operation is multiplication:

20 = 5 x 4
