mathematical concept; value which cannot be changed or does not change during a process

AI overview

A constant is a value in mathematics that stays the same and doesn't change, unlike a variable which can take on different values. Constants matter because they serve as reliable, unchanging reference points that help us describe and solve mathematical problems accurately.

Encyclopedic overview

In mathematics, the word constant conveys multiple meanings. As an adjective, it refers to non-variance (i.e. unchanging with respect to some other value); as a noun, it has two different meanings:

A fixed and well-defined number or other non-changing mathematical object, or the symbol denoting it. The terms mathematical constant or physical constant are sometimes used to distinguish this meaning.
