# What's the inverse operation?

• Inverse operations are opposite operations that undo each other. Addition and subtraction are inverse operations. Multiplication and division are inverse operations.

• Examples of inverse operations are: addition and subtraction; multiplication and division; and squares and square roots.

Beside above, why are inverse operations important? That is why inverse operations are so important when dealing with real numbers : an Inverse Operation reverses the effect of an operation (an operation is a procedure such as addition or multiplication) and gets you back to the number you started with. The inverse operation of addition is subtraction .

Likewise, people ask, how do you calculate the inverse?

Finding the Inverse of a Function

1. First, replace f(x) with y .
2. Replace every x with a y and replace every y with an x .
3. Solve the equation from Step 2 for y .
4. Replace y with f−1(x) f − 1 ( x ) .
5. Verify your work by checking that (f∘f−1)(x)=x ( f ∘ f − 1 ) ( x ) = x and (f−1∘f)(x)=x ( f − 1 ∘ f ) ( x ) = x are both true.

What is the inverse in math?

In mathematics, the word inverse refers to the opposite of another operation. Let us look at some examples to understand the meaning of inverse. Example 1: The addition means to find the sum, and subtraction means taking away. So, subtraction is the opposite of addition.
