equation

n. making equal; statement demonstrating the equality of two quantities (Mathematics); equally balanced state

This article is about equations in mathematics. For the chemistry term, see chemical equation. An equation is a mathematical statement, in symbols, that two things are the same (or equivalent). Equations are written with an equal sign, as in.The equation above is an example of an equality: a proposition which states that two constants are equal. Equalities may be true or false.Equations are often used to state the equality of two expressions containing one or more variables. Taking the  Real numbers  we can say, for example, that given any value of , it is always true that.
