## Introduction

Logarithms are a fundamental concept in mathematics, particularly useful in various fields such as algebra, calculus, and complex number theory. They are the inverse operation of exponentiation, just as division is the inverse of multiplication.

## Definition of Logarithms

The logarithm of a number is the exponent to which another fixed number, the base, must be raised to produce that number.
