U+2A2A
⨪ is a Unicode math character known as the minus sign with dot below. It’s mainly used in technical and mathematical contexts where a standard minus sign isn’t specific enough.
Minus Sign With Dot Below Symbol Meaning
⨪ (Unicode U+2A2A) is the “minus sign with dot below.” In mathematics and related technical writing, it can be used to distinguish a specific kind of subtraction or a modified minus operator from a plain minus sign. Because this character is part of the Math category, you’ll most often see it in formulae, typeset documents, or notation systems where the dot-below carries meaning (for example, indicating a variant operator or emphasizing a different operation). When you need a symbol that looks like a subtraction sign but with extra punctuation, ⨪ provides that precise glyph.
Common uses
- •Writing math notations that require a minus sign variant with a distinguishing dot below.
- •Typesetting technical documents where plain “−” is insufficient to match a specific convention.
- •Labeling or annotating formula components in educational materials and worksheets.
- •Creating consistent symbol sets for math-aware design systems and UI typography.
- •Using the exact Unicode character in digital publishing to avoid fallback glyph differences.
