Supplemental Mathematical Operators is a Unicode block containing various mathematical symbols, including N-ary operators, summations and integrals, intersections and unions, logical and relational operators, and subset/superset relations.

Block

Variation sequences

The Supplemental Mathematical Operators block has eight 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
Base character Base +VS01 Description
U+2A3C INTERIOR PRODUCT ⨼ ⨼︀ tall variant with narrow foot
U+2A3D RIGHTHAND INTERIOR PRODUCT ⨽ ⨽︀ tall variant with narrow foot
U+2A9D SIMILAR OR LESS-THAN ⪝ ⪝︀ with similar following the slant of the upper leg
U+2A9E SIMILAR OR GREATER-THAN ⪞ ⪞︀ with similar following the slant of the upper leg
U+2AAC SMALLER THAN OR EQUAL TO ⪬ ⪬︀ with slanted equal
U+2AAD LARGER THAN OR EQUAL TO ⪭ ⪭︀ with slanted equal
U+2ACB SUBSET OF ABOVE NOT EQUAL TO ⫋ ⫋︀ with stroke through bottom members
U+2ACC SUPERSET OF ABOVE NOT EQUAL TO ⫌ ⫌︀ with stroke through bottom members
