The equal sign, equals sign, or "=" is a mathematical symbol used to indicate equality. It looks like two parallel horizontal lines. The equals sign is placed between the things stated to be exactly equal or the same. Computers display the equals sign with the Unicode or ASCII character 003D (in hexadecimal).

The symbol used to say when items are not equal is "≠" (slashed equal sign).

There are several symbols that can be used to say items are "approximately the same," "similar to" or "about equal." Some of these symbols include "≈" (two tildes or wavy lines), "⩰" (two tildes above two lines), "≅" (one tilde above two lines), "≃" (one tilde above one line), "~" (one wavy line), "≐" (two lines with a dot above them). Each of these symbols has more than one possible meaning. Again these are all ways of showing something is about equal.
