What Is an Algorithm?

An algorithm is a finite, step-by-step set of instructions for solving a problem or completing a task. Computers run algorithms for everything from sorting lists to recommending videos, but the idea is older than computers — a recipe or the method for long division are algorithms too.

Algorithms in Everyday Tools

Every calculator follows an algorithm: for example, a loan calculator applies a fixed sequence of formulas to the amount, rate, and term to produce a monthly payment.

Algorithms vs. AI

A traditional algorithm follows rules written by people. Machine learning uses algorithms to learn rules from data.
