Step 1: Start typing your math equation
Step 2: Type the + symbol
Step 3: Then type the - symbol, with no space after the +.
Instantly, the plus/minus symbol will appear like this:
Step 4: Finish typing your equation. When you finish press "shift-enter" to skip solving. (If you hit "enter" an error code will appear after the equals sign. FastFig does not currently solve for plus/minus, sorry.)
Minus/Plus is also possible, just switch the order of typing. Type - first, then type the + sign.
