Whatever color they land on when they spin, this is the color of card they will draw.
If they answer the math problem correctly, they will move forward the number of spaces indicated.
If they get the answer wrong, they will move backwards that many spaces, or back to START if there are not enough spaces back to go.
If you get the math problem right, you keep the card.
If you get the math problem wrong it goes back at the bottom of the stack.
