Matrix inverses and determinants, square and nonsingular, the equations AX = I and XA = I have the same solution, X. This solution is called the inverse of A.
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.
The answer depends on the context. There are opposite numbers that can be the additive inverses, or multiplicative inverses.

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.
Integers comprise the set of counting numbers, their additive inverses and zero. They are not operational functionals.

Equations can be tricky, and solving two step equations is an important step beyond solving equations in one step. Solving two-step equations will help introduce students to solving equations in multiple steps, a skill necessary in Algebra I and II. To solve these types of equations, we use additive and multiplicative inverses to isolate and solve for the variable.

That a and b are additive inverses of one another.
They are bijections.

Not necessarily. Negatives are called opposites, or additive inverses. Inverses is much more general. For example, the inverse of an exponent is a logarithm.
Inverse oprations. Here are some examples (with some values excluded where one or the other operation is not defined or where one of the functions is not uniquely defined): Addition and subtraction are inverses of each other, Multiplication and division are inverses of each other, Exponentiation and logariths are mutual inverses, Trigonometric functions and their arc equivalents are mutual inverses, Clockwise rotation and anticlockwise rotation are mutual inverses. Squaring (a non-negative number) and the principal square-root of a non-negative number.
