The **not equal sign** is used to indicate inequality, when two things are not equal to one another. For example,
0 is not equal to 1, which we express as 1 ≠ 0. The not equal sign takes the form of the equal sign with a slash through it.
If you can't find the **not equal sign** on your keyboard, you can copy it using the button above.

To type the not equal sign on a Windows computer, hold down the **Alt** key and type
**8800** on your number pad (ensure that the Numlock is turned on). If you don't have a number pad
you can copy the sign at the top of this page, or use the character map in Windows.

Alt + 8 8 0 0

On a Mac, you can type the not equal sign by holding down the **option key (â¥)** and pressing
the **equal key (=)**.

â¥ + =

To display the not equal sign in Latex, use the code **\neq**.

In programming, the not equal sign is usually expressed as **!=** or **<>** or **~=**, which are the inverse of the equality operator (**==**). For instance, **a != true** will test whether the variable
a is not equal to true. A great overview of different inequality operators used in programming is provided here.

The not equal sign (also called the inequality sign) is part of a family of symbols used to indicate inequality between values. The most common of these are less than (<) and greater than (>) symbol, which indicate that the value before the sign is less than or greater than the value after the sign, respectively.

The not-equal sign specifically indicates that two values are not equal to one another. For instance, the following statement shows that x cannot be equal to 5. It can also be seen as x is equal to everything but 5:

**x ≠ 5**
