Minus Sign Symbol

There is no legacy Windows Alt code for Minus Sign because it is not in either the OEM code page 437 or Windows-1252 tables. The Unicode codepoint is U+2212, which you can use as − in HTML, \2212 in CSS, or type with Alt+8722 on Windows (BMP only). If your keyboard has no numeric keypad, use the Character Viewer, the HTML entity, or copy the character directly. Minus Sign is outside both legacy code pages, which is why U+2212 is the identifier that works across Word, HTML, CSS, Python and JavaScript. HTML also defines the named entity − for Minus Sign, but the numeric form − is safer when compatibility is uncertain.
