Recreational mathematics From Wikipedia, the free encyclopedia Jump to: navigation search This article does not cite any references or sources Please help improve this article by adding citations to reliable sources . Unsourced material may be challenged and removed (July 2008) Recreational mathematics is an umbrella term, referring to mathematical puzzles and mathematical games Not all problems in this field require a knowledge of advanced mathematics, and thus, recreational mathematics often attracts the curiosity of non-mathematicians, and inspires their further study of mathematics. Contents Topics Mathematical games Mathematical puzzles Others ... edit Topics This genre of mathematics includes logic puzzles and other puzzles that require deductive reasoning, the aesthetics of mathematics, and peculiar or amusing stories and coincidences about mathematics and mathematicians. Some of the more well-known topics in recreational mathematics are magic squares and fractals edit Mathematical games Mathematical games are multiplayer games whose rules, strategies, and outcomes can be studied and explained by mathematics . The players of the game may not need to use mathematics in order to play mathematical games. For example

4. Recreational Math The preoccupation of stating and resolving recreational math problems is centuries old and it has most likely evolved along with math theory from its early beginnings. http://integralsnet.com/recreational_math.htm

1232 * 3 = ? y = x + 4 ln x = 1 sin2x = 2 * sinx * cosx f(x) o g(x) = h(x)  Recreational Math The preoccupation of stating and resolving recreational math problems is centuries old and it has most likely evolved along with math theory from its early beginnings. The word problems have an increased degree of difficulty if one tries to solve them arithmetically only, and avoid using algebra, but a great sense of spiritual accomplishment comes with mastering these techniques. So, are you ready to take the challenge? Get the pencil and a piece of paper and set to work! 1. 2 skiers are set for a race. One of them start early and gets down the slope with an average speed of 2.6 m/sec. The second one starts 10 seconds later with an average speed of 2.8 m/sec. They both reach the bottom of the slope at exactly the same time. What is the slope length and the corresponding times for the two skiers. 2. A group of children go sledging, but not every kid has his own sled. If 2 kids share a sled there are 8 children left with no sled. If 3 kids share a sled there are 3 unused sleds left. What are the total number of children and the total number of sleds? 3. What is the largest number 5^200 or 3^300?l The same question for 22^33 or 33^22?

David Eppstein About Contact Research Students ... Math Fun Like many, I was inspired early on by Martin Gardner's Mathematical Games column, which included a mixture of puzzles, silliness, curious/useless math, and quite serious (but not overly technical) math. In that spirit, I've collected many pages and links of recreational math web sites. My recreational math publications Number Theory . Implementations of some simple number-theoretic algorithms along with pointers to other number theory web pages. Combinatorial Game Theory . Mathematical strategies for games like chess, go, and nim. The Geometry Junkyard . Many links to recreational geometry web pages, open problem lists, lecture notes, usenet postings, and brief blurbs from my own papers. For more serious geometry links, see my Geometry in Action pages.

13. Recreational Math: Introduction Introduction to topics in recreational mathematics by Lionel Deimel. I was doing mathematics—arithmetic, at any rate—for recreation as early as age 6 http://www.deimel.org/rec_math/rec_math.htm

Previous Home Next I was doing mathematics—arithmetic, at any rate—for recreation as early as age 6, although it was not until I got to junior high school that I encountered what is generally known as recreational mathematics. It was in junior high that I encountered a charismatic teacher, Mrs. Eunice Williams, who gathered around her, Pythagoras-like, a group of talented math students and infected them with her excitement and love for mathematics. At least two students in my class eventually became professional mathematicians, and I studied computer science in graduate school and minored in math. In fact, when I had a rare opportunity to take a free elective in college, I chose a linear algebra course. In graduate school, one of my favorite courses was modern algebra. My dissertation was in automata theory, which comes perilously close to being a topic of recreational mathematics, which is how I viewed it while I was still an undergraduate. I enjoy mathematical puzzles and problems of all kinds, although I don’t spend a lot of time working on them. Every so often, however, a problem really engages me—particularly if it can be generalized—and the topic becomes consuming. Working on such a project helps me keep my mathematical skills sharp and gives me an excuse to do things that I wouldn’t normally do in the course of my work.
