The Skill Level Slider varies from levels 1 - 20. The complexity of each game card increases with higher level numbers. The < and > symbols operate in a similar manner as in the Addition and Subtraction games. The T symbol is new in the Division and Multiplication games. T means Tables. When the T is pressed, the divisor remains fixed for a given skill level. This allows you to create problems similar to division tables. To check your score of right and wrong, press SCORE. To play the Division game, press PLAY. To quit, press QUIT. In the PLAY screen you type your answer and press Enter. If you make a mistake you may TRY AGAIN. If you want to clear your answer press CLR. To learn the answer, press ANS.
