Abstract
An enhancement to a typical four-function calculator. With this enhanced calculator, lottery players may generate psuedo-random integer combinations for their use in selecting numbers on which to place their bets. The enhanced calculator allows users to select the type of lottery game for which the number combinations will be generated by specifying the quantity of numbers generated and the bounds of the range within which the numbers will be generated through two key strokes of dedicated keys. The first key stroke utilizes a key designated by the particular lottery game. The second key stroke utilizes a key designated by a popular range of numbers used by the various lotteries. This invention relieves the user from having to rely on his limited supply of "magical" dates, ages, social security numbers and so forth.
