# Definition of Inequality

An inequality is an expression that tells you that two values are not equal to each other.

There are a number of different symbols that tell you that two numbers are unequal, and which may describe the ways in which they differ from each other.

For example,

1. $x \neq y$ simply tells us that $x$ is not equal to $y$
2. $x 3. \(x > y$ tells us that $x$ is greater than $y$
4. $x \leq y$ tells us that $x$ is less than or equal to $y$
5. $x \geq y$ tells us that $x$ is greater than or equal to $y$

The symbols in 2. and 3. above are referred to as strict inequalities because they don't allow the two numbers to be equal.
