U+2A25 "⨥" Plus Sign with Dot Below Unicode Character
Unicode Version 17.0
⨥
U+2A25 "⨥" Plus Sign with Dot Below is a mathematical symbol used primarily in notation to indicate a modified or restricted addition operation, often implying that the addition is performed under a specific condition or within a particular algebraic structure. It belongs to the Supplemental Mathematical Operators block and is designed for use in formal logic, algebra, or set theory where a standard plus sign is insufficient. This character allows authors to distinguish between ordinary addition and a variant operation, such as addition modulo a subgroup, without cluttering an equation with extra annotations.
