mathematical symbols

Leave a space on either side of mathematical symbols used as operation signs.

The solidus (a/b) or division sign is an exception. Do not leave a space between numerals and the symbols for degrees, dollars, and percent (32°, $100, 17%). (However, leave a space between numerals and symbols of measurement such as cm and Å.) Do not leave a space between symbols such as >, <, and ≥ and the numeral unless they are the operation signs in an equation.
