Inequation

In mathematics, an inequation is a statement that two objects or expressions are not the same, or do not represent the same value. This relation is often written with a crossed-out equal sign, like

x ≠ y.

In some programming languages, this as a statement is written as

x != y or x <> y.

This concept should not be confused with an inequality, which expresses a numerical relation such as 3 < 5 ('3 is less than 5').
