# 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".
