Notes and Credits

The car can help you learn how to add and subtract with negative numbers, for example a problem like

-5 - -9 + -4.

Try entering a few problems and watch what the car does:

- sign: turns the car around.

a number: makes the car go that far, then point to the right.

That's it! Play around with it and before you know it you'll have no problem doing these types of problems on your own! This project uses single digit numbers only (no double digit numbers like 10, 20, etc.)

Have fun!
