Open the Mathletics application. Choose a level, from one to five, according to the player's age group or math level.
Play Mathletics against the computer by answering math questions as fast as you can. Since the ability does not exist within the program to erase an answer by hitting the "backspace" key, there really is no way to cheat the system in order to gain Mathletics credits. Once an incorrect answer is typed into the field, it becomes your final answer for that math question, so thinking ahead before submitting an answer can help you gain credits and points.
Practice Mathletics often. Race other players around the world in real-time within the program to sharpen your current math skill level. Practicing will promote learning and help you retrieve answers faster when playing against the computer. Earn credits in Mathletics by training yourself to be able to give correct answers more quickly. Your total score will be available for you to view, after a round, allowing you to see your progress, points and credits earned.
