Definition of Not Equal

Two numbers are not equal when they have different values.

We use the symbol \(\neq\) to indicate that the numbers or expressions to its left and right are not equal to each other.

For example, \(x \neq y\) says that \(x\) is not equal to \(y\), so \(7 \neq 17\) says that \(7\) and \(17\) have different values.

Another term for "not equal" is "unequal".


The aim of this dictionary is to provide definitions to common mathematical terms. Students learn a new math skill every week at school, sometimes just before they start a new skill, if they want to look at what a specific term means, this is where this dictionary will become handy and a go-to guide for a student.
