In mathematics, an inequation is a statement that an inequality holds between two values.^[1][2] It is usually written in the form of a pair of expressions denoting the values in question, with a relational sign between them indicating the specific inequality relation. Some examples of inequations are:

• ${\displaystyle a<b}$
• ${\displaystyle x+y+z\leq 1}$
• ${\displaystyle n>1}$
• ${\displaystyle x\neq 0}$

In some cases, the term "inequation" can be considered synonymous to the term "inequality",^[3] while in other cases, an inequation is reserved only for statements whose inequality relation is "not equal to" (≠).^[2]
