U+2A0A "⨊" Modulo Two Sum Unicode Character
Unicode Version 17.0
⨊
U+2A0A "⨊" Modulo Two Sum is a mathematical symbol used to denote the exclusive or (XOR) operation in logic and binary algebra, where the result is true only when an odd number of inputs are true. It appears as a plus sign enclosed within an elongated circle, resembling a modified summation symbol, and is typically employed in algebraic structures over the field with two elements or in expressing parity functions. This character belongs to the Supplemental Mathematical Operators block and serves as a compact notation for addition modulo 2, distinct from the regular plus sign to avoid ambiguity with ordinary addition.
