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 (-).

Variation sequences

The Mathematical Operators block has sixteen variation sequences defined for standardized variants.[3][4] They use U+FE00 VARIATION SELECTOR-1 (VS01) to denote variant symbols (depending on the font):
