I have seen variants of these used by people who predate widespread knowledge of computer programming. It would be interesting to know the earliest uses of a special symbol for this (and what symbols were chosen).

Equality $=$ is usually used for equality. $\equiv$ is occasionally used for "identically equal to," which is in a sense stronger than equality, by denoting that the thing on the left and the thing on the right are equal in a sense that they are identities of ...Mon, 13 Apr 2026 09:43:00 GMThttps://math.stackexchange.com/questions/62044/what-is-mathematical-basis-for-the-percent-symbolPercent means 1 part of 100 or 1/100 and is indicated with %.

A set of integers is "coprime" if no integer > 1 divides any pair of them. So for two integers the two definitions coincide, but for more than two the property of "coprimeness" is stronger, because for example a ...Sat, 11 Apr 2026 08:27:00 GMT
