U+2A01 "⨁" N-Ary Circled Plus Operator Unicode Character
Unicode Version 17.0
⨁
U+2A01 "⨁" N-Ary Circled Plus Operator is a mathematical symbol that represents a binary or n-ary operation, often used in algebra, logic, and computer science to denote the direct sum, exclusive or (XOR), or the addition of elements in a vector space or group. It resembles a plus sign enclosed within a circle, and its large, n-ary variant indicates that the operation can be applied to a sequence of multiple terms, similar to how a capital Sigma is used for summation. This operator is commonly employed in contexts such as set theory, linear algebra, and digital circuit design to combine structures or values in a modular or symmetric manner.
