Inverse Operations
Operation is a mathematical process involving addition, subtraction, multiplication, division, squaring, square roots, etc.
All the given symbols (+, −, ×, ÷) in mathematics are known as operators.
An inverse operation reverses the effect of the first operation.
For example, if we operated adding two numbers say 5+3 = 8
The inverse operation of this would be the subtraction of these two numbers: 5-3= 2.

Properties of Inverse Operations
Inverse additive property: The inverse operation of the addition of two same numbers will result in a zero.
2 + (-2) = 0
or
When we add a number to its opposite, the result is always 0.
Inverse multiplicative property: When we multiply a number is by its (multiplicative) inverse, the result is always 1.
Multiplicative inverse of 10 is 1⁄10
So, 10 × 1⁄10=1
Additive Property: Consider the operation , 5 + 0 = 5
The inverse operation is, 5- 0 = 5
Thus, when we add any number to zero, both the operation and inverse operation will give the same number.
Multiplicative Property: Consider the operation, 5 × 1 = 5
The inverse operation is, 5 ÷ 1 = 5
Thus, when we multiply any number with 1, both the operation and inverse operation will give the same number.
