Mathematical Operators is a Unicode block containing characters for mathematical, logical, and set notation.
Notably absent are the plus sign (), greater than sign () and less than sign (), due to them already appearing in the Basic Latin Unicode block, and the plus-or-minus sign (), multiplication sign () and obelus (), due to them already appearing in the Latin-1 Supplement block, although a distinct minus sign () is included, semantically different from the Basic Latin hyphen-minus (-).
The Mathematical Operators block has sixteen variation sequences defined for standardized variants. They use (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:
