Mathematical Operators
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, differing from the Basic Latin hyphen-minus.

Variation sequences
The Mathematical Operators block has sixteen variation sequences defined for standardized variants. They use to denote variant symbols :| Base character | Base | +VS01 | Description |
| 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 | ||
| U+2272 LESS-THAN OR EQUIVALENT TO | following the slant of the lower leg | ||
| U+2273 GREATER-THAN OR EQUIVALENT TO | following the slant of the lower leg | ||
| U+228A SUBSET OF WITH NOT EQUAL TO | with stroke through bottom members | ||
| U+228B SUPERSET OF WITH NOT EQUAL TO | with stroke through bottom members | ||
| U+2293 SQUARE CAP | with serifs | ||
| U+2294 SQUARE CUP | with serifs | ||
| U+2295 CIRCLED PLUS | with white rim | ||
| U+2297 CIRCLED TIMES | with white rim | ||
