U+207B "⁻" Superscript Minus Unicode Character
Unicode Version 17.0
⁻
U+207B "⁻" Superscript Minus is a typographic symbol used primarily in mathematical and scientific notation to indicate a negative exponent or a superscripted minus sign, such as in expressions like 10⁻³. It is part of the Superscripts and Subscripts block and is distinct from the regular hyphen-minus or the minus sign, as it is specifically designed to be smaller and positioned above the baseline for clarity in formulas. This character is essential for accurate digital representation of chemical formulas, physics equations, and other contexts where a compact, raised negative sign is required.
