Use the arrow keys to move. When you hit a math problem, answer it correctly or else you will have to start over. If you hit a math problem and the problem does NOT ask you a question don't panic. All you have to do is press the stuck button. You will start over EXCEPT, all the problems you completed will stay completed. Don't touch the black lines or you will start over. READY, SET, SOLVE!!!!
You can use paper to solve the last problem. Pheep helped me.
