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 (-).

Variation sequences

[edit | edit source]

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):

Variation sequences

U+2205 EMPTY SET ∅ ∅︀ zero with long diagonal stroke overlay form
U+2229 INTERSECTION ∩ ∩︀ with serifs
U+222A UNION ∪ ∪︀ with serifs
U+2268 LESS-THAN BUT NOT EQUAL TO ≨ ≨︀ with vertical stroke
U+2269 GREATER-THAN BUT NOT EQUAL TO ≩ ≩︀ with vertical stroke
