Circled Division Slash Symbol
⊘ is the circled division slash symbol (U+2298), used to represent a division-with-slash concept in math notation.
U+2298
The symbol ⊘ is known as the circled division slash. It comes from the Unicode “CIRCLED DIVISION SLASH” character (U+2298). You can copy it directly or use its Unicode/HTML code in documents and code.
Circled Division Slash Symbol Meaning
⊘ (Unicode U+2298) is the “CIRCLED DIVISION SLASH” character. Visually, it combines a division slash idea with a surrounding circle, which helps it stand out in typed math. In mathematical contexts, it’s often used to indicate a “division that is altered by a slash” concept—commonly understood as a restricted, undefined, or excluded division-like operation. Depending on the source and notation system, it may also function as a shorthand in specialized symbol sets where a circled slash indicates prohibition or non-applicability in a mathematical expression. It’s most reliable when used consistently with the same intended meaning in a given document or stylesheet.
Common uses
- •Math typesetting to indicate an excluded or modified division operation
- •Editing or annotating technical documents where division is not applicable
- •Labeling UI elements or diagrams that represent an invalid/blocked “divide” action
- •Creating custom mathematical symbol legends and teaching materials
- •Using as a distinct standalone marker for “division not allowed” in worksheets
Examples
