# Algorithm vs. Formula: What's the Difference?

Edited by Aimie Carlson || By Janet White || Published on November 11, 2023
An algorithm is a step-by-step procedure for calculations or problem-solving, while a formula is a concise way of expressing information symbolically.

## Key Differences

An algorithm is a detailed set of instructions or processes to achieve a particular outcome or solve a specific problem. It's a general solution to a category of problems in terms of actions to be executed. Conversely, a formula is a fixed, concise sequence of mathematical symbols that produces a specific result.
Algorithms can be implemented in various programming languages and can be applied in numerous areas like computer science and data analysis. They dictate how a particular task is executed. Formulas, on the other hand, are commonly associated with mathematics, physics, and chemistry, and they give direct calculations to obtain results.
The concept of an algorithm is broader than that of a formula. For example, sorting numbers in ascending order can be achieved using various algorithms, each with different steps and efficiencies. In contrast, the quadratic formula is a specific expression used to solve quadratic equations.
In practical applications, an algorithm might use multiple formulas to carry out its steps. For instance, a computer algorithm designed to solve complex mathematical problems might use a variety of formulas during its execution. It's essential to recognize that while all formulas can be part of an algorithm, not all algorithms are formulas.
