Math Speed Racing Subtraction

See how many miles you can rack up by keeping your race car fueled up and avoiding other cars.  Fuel up by matching your race car's answer to the correct "subtraction problem" fuel tank.  Game over if you run out of fuel or run into another racer.

Your race car will have a number beside it which will answer at least one of the subtraction problems by each fuel tank.  Run into the correct fuel tank to get extra fuel.  Hit the wrong tank and you'll lose fuel.  See how far you can go before you run out of fuel or crash!  Collecting coins add to your score.
