Squared Dot Operator Symbol

⊡ is the Squared Dot Operator (U+22A1), a math symbol used in specialized notation.

U+22A1

The symbol ⊡ is known as the Squared Dot Operator (Unicode U+22A1). It’s primarily used in mathematical and technical contexts where a distinct operator symbol is helpful. This page helps you understand its basic identity and copy it reliably.

Squared Dot Operator Symbol Meaning

⊡ is the Unicode character named “SQUARED DOT OPERATOR” (U+22A1). As a math-category symbol, it’s typically used as an operator in written or typeset notation—often alongside other operators to represent a specific action, transformation, or relationship defined by a particular system (for example, within a document, worksheet, or software display). Because the exact meaning can depend on the author’s convention or the surrounding notation, it’s best treated as a dedicated operator glyph rather than something with a single universal interpretation. When you need a consistent symbol in formulas, ⊡ can be a practical choice.

Common uses

  • •Using as an operator glyph in math notes or formula-like text
  • •Adding a distinct symbol in technical documentation to match a defined notation system
  • •Labeling steps or transformations in educational materials and worksheets
  • •Representing a specialized operator in code documentation or UI math displays
  • •Designing typographic elements or icons for math-themed graphics
