Mathematical Operators (Unicode block)

Mathematical Operators (unicode block) are a group of symbols on a computer keyboard that are used to do calculations. The symbols look like shapes and letters, and they help us do things like add, subtract, multiply and divide numbers more quickly. For example, the plus sign (+) is an operator that adds two numbers together, so if you typed in “2+2” the computer would give you “4” as an answer.
