Mathematical Operators is a Unicode block containing characters for mathematical, logical, and set notation.

Notably absent are the plus sign (${\displaystyle +}$), greater than sign (${\displaystyle >}$) and less than sign (${\displaystyle <}$), due to them already appearing in the Basic Latin Unicode block, and the plus-or-minus sign (${\displaystyle \pm }$), multiplication sign (${\displaystyle \times }$) and obelus (${\displaystyle \div }$), due to them already appearing in the Latin-1 Supplement block, although a distinct minus sign (${\displaystyle -}$) is included, semantically different from the Basic Latin hyphen-minus (-).

The Mathematical Operators block has sixteen variation sequences defined for standardized variants. They use U+FE00 VARIATION SELECTOR-1 (VS01) to denote variant symbols (depending on the font):

The following Unicode-related documents record the purpose and process of defining specific characters in the Mathematical Operators block:
