Math Help - Fun Arithmetic Help - Integer Subtraction - Game Tips:

- To subtract an integer, you can add its opposite.
- That means (-3)-(+7) is the same as (-3)+(-7) = -10.
- Also (6)-(-2) is the same as (+6)+(+2)=8, because removing a $2 loss gives a $2 gain.

- It may take a minute to load the game at dial-up speeds.
- The game can be played using the mouse by itself or using the keyboard by itself.
- If the game doesn't respond to keyboard input, click inside the game area to reset the game's focus.
