Note: ^{[1]}^{[2]} 
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 plusorminus sign (±), multiplication sign (×) and obelus (÷), due to them already appearing in the Latin1 Supplement block, although a distinct minus sign (−) is included, differing from the Basic Latin hyphenminus ().

Variation sequences
The Mathematical Operators block has sixteen variation sequences defined for standardized variants.^{[3]}^{[4]} They use U+FE00 VARIATION SELECTOR1 (VS01) to denote variant symbols (depending on the font):
Base character  Base  +VS01  Description 

U+2205 EMPTY SET  ∅  ∅︀  zero with long diagonal stroke overlay form 
U+2229 INTERSECTION  ∩  ∩︀  with serifs
