# Inverse vs. Reciprocal: What's the Difference?

Edited by Huma Saeed || By Sumera Saeed || Published on January 8, 2024
The inverse is a general term for an operation that reverses another operation, while the reciprocal specifically refers to dividing 1 by a number.

## Key Differences

The inverse refers to something that is opposite in position, direction, or effect, often used in various mathematical and non-mathematical contexts. Reciprocal, however, is a specific mathematical term, representing the multiplicative inverse of a number.

An inverse relationship implies that when one variable increases, the other decreases, and vice versa. This concept is broad and can apply to functions, operations, or even concepts. Reciprocal is narrowly defined, focusing solely on the concept of one divided by the number, a fundamental operation in arithmetic.

In mathematics, the inverse of a function essentially undoes the action of that function. For example, the inverse of addition is subtraction. In contrast, the reciprocal of a number deals with multiplication, as multiplying a number by its reciprocal always yields 1.

The term 'inverse' can also be found in non-mathematical contexts, implying a reversal or opposite nature in various situations. However, 'reciprocal' is almost exclusively used in mathematical contexts, particularly in arithmetic and algebra.
