Inverse operations are opposite operations that undo each other. Addition and subtraction are inverse operations. Multiplication and division are inverse operations.
Additive inverses
opposites, additive inverses
Reciprocals, or multiplicative inverses
The inverse of PEMDAS is the opposite operation order such as: S=subtraction, A=addition, D=division, M=multiplication, E=exponents, and P=parentheses.
They are bijections.

Two integers which sum to zero (e.g. 3 and -3) are additive inverses of each other. All pairs of additive inverses sum to 0 and all pairs of integers which sum to 0 are additive inverses.
Two matrices ( A ) and ( B ) are inverses of each other if their product results in the identity matrix. Specifically, this means that ( AB = I ) and ( BA = I ), where ( I ) is the identity matrix of the same size as ( A ) and ( B ). If both conditions are satisfied, then ( A ) and ( B ) are indeed inverses. If either product does not equal the identity matrix, then the matrices are not inverses.
There are two main types of inverses. Additive inverses total zero. Any number and its negative are inverses. 3 and -3 are inverses. Multiplicative inverses total 1. 3/4 and 4/3 are inverses. 3/4 x 4/3 = 12/12 = 1 Most often, the word inversely in math means upside down.
