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 >} ), equals 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 division sign ( ÷ {\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 (-).
Block
Variation sequences 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):
History The following Unicode-related documents record the purpose and process of defining specific characters in the Mathematical Operators block:
