Microsoft Word offers a pre-defined shortcut key for some symbols such as plus-minus sign and minus-plus sign:
Type 00b1 or 00B1 (does not matter, uppercase or lowercase) and immediately press Alt+X to insert the plus-minus symbol: ±
Type 2213 and press Alt+X to insert the minus-plus symbol: ∓
Why do we use +-?
To indicate that we want both the positive and the negative square root of a radicand we put the symbol ± (read as plus minus) in front of the root. Zero has one square root which is 0. Negative numbers doesn’t have real square roots since a square is either positive or 0.
