# Operation in math

An operation in math is a mathematical action upon numbers resulting in only 1 number.

For example, 12 + -9 = 3 is an operation on two numbers resulting in 3.

An operation can also be performed on only 1 number resulting in only 1 number.

For example, 7^{2} = 49 is also an operation.
