# 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".
