math symbolsUse real symbols, not alphabetic characters
If you need math symbols infrequently—some light addition and subtraction, the occasional negative number—you can get by without special symbols. Use the plus sign (+) and equals sign (=) as usual. Use the en dash as a minus sign (–) (see hyphens and dashes).
If you need to do multiplication or beyond, insert real math symbols by hand.
