Recommend this site Interactive Mathematics Miscellany and Puzzles Raymond Smullyan, a Mathematician, Philosopher and author of several outstanding books of logical puzzles, tells, in one of his books, a revealing story. A friend invited him for dinner. He told Smullyan that his teenage son was crazy about Smullyan's books and could not wait to meet him. The friend warned Smullyan not to mention that he is a Mathematician and that Logic is a part of Mathematics because the young fellow hated Mathematics.

Mathematical games and recreations Alphabetical list of History Topics History Topics Index Mathematical puzzles vary from the simple to deep problems which are still unsolved. The whole history of mathematics is interwoven with mathematical games which have led to the study of many areas of mathematics. Number games, geometrical puzzles, network problems and combinatorial problems are among the best known types of puzzles. The Rhind papyrus shows that early Egyptian mathematics was largely based on puzzle type problems. For example the papyrus, written in around 1850 BC, contains a rather familiar type of puzzle. You can see a picture of the Rhind papyrus Seven houses contain seven cats. Each cat kills seven mice. Each mouse had eaten seven ears of grain. Each ear of grain would have produced seven hekats of wheat. What is the total of all of these? Similar problems appear in Fibonacci 's Liber Abaci written in 1202 and the familiar St Ives Riddle of the 18 th Century based on the same idea (and on the number 7). Greek mathematics produced many classic puzzles. Perhaps the most famous are from

The program includes Multiple Choice Warm-up games and Three, Four, and Five Number Puzzle games. The problems are easy enough for a third grader to master, but at higher levels they will challenge even a math wizard. Watch your math scores climb dramatically as your rank advances from Learner all the way up to Math Genius. There are three levels of Warm-up games (Basic, Intermediate, and Advanced). The Basic game lets you select addition, subtraction, multiplication, and division to practice on. The Intermediate game randomly uses any one of the four operations. The Advanced game also uses any one of the four operations of addition, subtraction, multiplication, and division in its problems. However, you must find ALL of the correct answers. For example if the question was 3 ? 6 = ? and your answer choices were 2, 3, 6, 9, and 18, you must click on four numbers (2, 6, 9 and 18). These Multiple Choice Warm-up games prepare you to play the Three, Four, and Five Number Puzzle games by making you familiar with using all of the operations of addition, subtraction, multiplication, and division in problem solving.
