Inequation

In mathematics, an inequation is a statement that an inequality holds between two values. 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", while in other cases, an inequation is reserved only for statements whose inequality relation is "not equal to" (≠).
