Amazing mathematical "magic" square. A spectator names any two digit number between 22-99 and after you fill in the 16 boxes there will be 28 possible combinations where the boxes will add up to the spectators number.

http://tomscott.com - @tomscott - No, seriously. Here's how to read text when all you can see is a bunch of 0s and 1s. It's easier than it seems. I... I think I might have gone off the deep end a bit here.
A puzzle to try on your friends and family, using something called an Euler's Trail http://en.wikipedia.org/wiki/Euler_trail Puzzle sent to me by Obivandamme http://www.youtube.com/user/obivandamme All mistakes in the solution are my own.
Get the full course at: http://www.MathTutorDVD.com In this lesson, the student will learn how to find the prime factors of a number and how to write the prime factorization down. The easiest way to do this is to write down the factors in a "factor tree". The prime factors are the numbers at the "bottom" of the factor tree. Finding factors of a number (number factors) isn't hard. In fact, math factoring is very easy once this simple technique of using a factor tree is understood.
