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 Multiplication and Division games. T means Tables. When the T is pressed, the multiplicand remains fixed for a given skill level. This allows you to create problems similar to multiplication tables.
