Inverse Operations in Math: Definition & Examples The word 'inverse' means reverse in direction or position. It comes from the Latin word 'inversus,' which means to turn upside down or inside out. In mathematics, an inverse operation is an operation that undoes what was done by the previous operation. The four main mathematical operations are addition, subtraction, multiplication, division. The inverse of addition is subtraction and vice versa. The inverse of multiplication is division and vice versa.

- Multiplicative inverses. That's a mouthful! Really, this term just refers to numbers that when multiplied together equal 1. These numbers are also called reciprocals of each other! Learn about multiplicative inverses by watching this tutorial.

Inverse problem It is called an inverse problem because it starts with the results and then calculates the causes. This is the inverse of a forward problem, which starts with the causes and then calculates the results. Inverse problems are some of the most important mathematical problems in science and mathematics because they tell us about parameters that we cannot directly observe.

What does an inverse operation mean? An inverse operation (for some operation) is, in a way, the opposite of another operation. For example, subtraction is the opposite of addition (if you add 7, then subtract 7, … the subtraction will undo the addition-you get the original number back).

- Inverse function. In mathematics, an inverse function (or anti-function) is a function that reverses another function: if the function f applied to an input x gives a result of y, then applying its inverse function g to y gives the result x, and vice versa. i.e., f(x) = y if and only if g(y) = x.

Inverse Tangent Inverse Tangent. The inverse tangent is the multivalued function (Zwillinger 1995, p. 465), also denoted (Abramowitz and Stegun 1972, p. 79; Harris and Stocker 1998, p. 311; Jeffrey 2000, p. 124) or (Spanier and Oldham 1987, p. 333; Gradshteyn and Ryzhik 2000, p. 208; Jeffrey 2000, p. 127), that is the inverse function of the tangent.

Sine The inverse function of sine is arcsine (arcsin or asin) or inverse sine (sin −1). As sine is non-injective, it is not an exact inverse function but a partial inverse function. For example, sin(0) = 0, but also sin(π) = 0, sin(2π) = 0 etc.

- Additive inverse. In mathematics, the additive inverse of a number a is the number that, when added to a, yields zero. This operation is also known as the opposite, sign change, and negation. For a real number, it reverses its sign: the opposite to a positive number is negative, and the opposite to a negative number is positive.
