    1. Coins
      There are 12 coins. One of them is false; it weights differently. It is not known, if the false coin is heavier or lighter than the right coins. How to find the false coin by three weighs on a simple scale?

    This problem was recently published in MAA on line: Crossing a Rickety Bridge at Night By Flashlight.
      A group of four people has to cross a bridge. It is dark, and they have to light the path with a flashlight. No more than two people can cross the bridge simultaneously, and the group has only one flashlight. It takes different time for the people in the group to cross the bridge:
        A nnie crosses the bridge in 1 minute

Math Puzzles #1 Home Art Math Business This section is for math teachers, math students, and lovers
of math puzzles. We hope that these puzzles, which will change
monthly, will keep you and/or your students busy for hours!
The answers to these will be posted when the succeeding set
of problems are posted. Good luck! 1) Find all solutions of this system of equations: x + yz = 6
y + xz = 6
z + xy = 6 2) Find the ordered pair (x,y) that satisfy: sqrt(21/4 + 3 * sqrt(3)) = x + sqrt(y) where sqrt means square root. 3) Find all ordered pairs of real numbers (x,y) that satisfy: 2x^2 - 2xy + y^2 = 2
3x^2 + 2xy - y^2 = 3 4) Factor 5^1995 - 1 (that's five to the 1995th power) into a product
of three integers, such that each factor is greater than 5^100. 5) Find all ordered pairs of real numbers (a,b) for which: 3 * sqrt(x - 2y) + 3 / sqrt(x - 2y) = 10
x = ay + b 6) The points of intersection of the graphs of xy = 20 and x^2 + y^2 = 41 are joined to form a convex quadrilateral. Find the area of that quadrilateral. 7) Find all ordered triples of real numbers (x,y,z) that satisfy:

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.
Having told this story, would it be wise to announce up front what this site is about? Perhaps against a better judgement, I've put together a manifesto that aims to explain the purpose of this site.

    20. Nick's Mathematical Puzzles

    Nick's Mathematical Puzzles
    Welcome to my selection of mathematical puzzles. I aim to add one new puzzle each week, so please stop by again. What's new? See puzzles 116 onwards The math puzzles presented here are selected for the deceptive simplicity of their statement, or the elegance of their solution. They range over geometry, probability, number theory, algebra, calculus, trigonometry, and logic. All require a certain ingenuity, but usually only pre-college math. Some puzzles are original. Explaining how an answer is arrived at is more important than the answer itself. To this end, hints, answers, and fully worked solutions are provided, together with links to related mathematical topics. Further references are provided with many of the solutions. The puzzles are intended to be fun, with an educational element. Each puzzle is assigned a level of difficulty of between one and four stars, with four being the most difficult. Clearly this is to some extent subjective, but it may be useful as a rough guide. The source for each problem is given at the bottom of the solution page. I usually provide only a proximate credit; some math puzzles have been around for so long it can be difficult to trace their provenance. However, if I know the original source, such as when a puzzle is a recognized mathematical theorem, I credit that source.
