Mathematical Operators (Unicode block)

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

Notably absent are the plus sign (+), greater than sign (&gt;) and less than sign (&lt;), 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 (&minus;) is included, semantically different from the Basic Latin hyphen-minus (-).

Variation sequences
The Mathematical Operators block has sixteen variation sequences defined for standardized variants. They use (VS01) to denote variant symbols (depending on the font):
