Grandpa’s Magic Square Puzzle

When I was a boy, my grandfather used to give me puzzles for me to solve. The following puzzle is one of them. A magic square is an arrangement of numbers from 1 to n² in an n² matrix in which each number should only occur once. Every row, column, and diagonal of a magic […]

Learn A Basic Number Theorem Through Playing Cards

The following is a simple activity for learning a simple number theory concept. This is based on the procedure described by Martin Gardner in Time Travel and Other Mathematical Bewilderments (1988). All you need for this is a pack of cards. First, remove all the cards of one suit (e.g. all the spades). Afterwards, arrange the […]

Zero Sum And Difference Game

Consider this group of squares: 1237892 + 5619452 + 6428642 – 2428682 – 7619432 – 3237872 = 0 When looking at the calculation above, it seems that it’s not a big deal. Although the six large squares yield zero after the calculation, it is not really that peculiar. But, try to remove the hundred thousands place or the left-most digit of […]

The Curious Collatz Conjecture

Select any whole number greater than zero then perform the following operation: If the number is even, divide it by 2. If the number is odd, multiply it by 3 and add 1. It’s said that if you continue to repeatedly apply the process, you’d always end up at 1. This is the premise of […]

Pun Of The Weak: Math Booths

I went to a math conference, and they had booths set up for several different branches of mathematics so students could learn about them. Unfortunately, the topology booth was closed, the algebra booth was way out in a field, and although I could get arbitrarily close to the analysis booth, I couldn’t touch it. The […]

20 Excuses For Not Doing Your Math Homework

This is a list I made quite some time ago. Might as well publish it here. 1. Even Galileo didn’t know calculus, so why should I? 2. When I tried to reach my textbook, I could only reach half the distance, then when I tried to reach it again, I could only reach half of […]
