Question

What does inverse mean?

Answer 1

Term used in Mathematics:

The inverse means the opposite of a mathematical operation.

Addition and subtraction are inverses of each other also multiplication and division are inverses of each other.

• Additive inverse: A additive inverse is a number that when added by a number gives $0$ as the output.

Example: The additive inverse of $10$ is $-10$, since $10+\left(-10\right)=0$

• Multiplicative inverse: A multiplicative inverse of a number is a reciprocal of that number. The product of both numbers is $1$.

Example: The multiplicative inverse of $7$ is $\frac{1}{7}$, since $7\times \frac{1}{7}=1$.

Hence,the meaning of inverse is explained.
