Even though I’m not hugely interested in math, I enjoy hearing things about numbers and mathematical problems if they don’t make my brain hurt.
If you’re like me, here’s a web page to check out: What’s Special About This Number?
It lists the numbers from 0 to 500 and gives interesting facts about each number.
For example, about the number 4:
“Pick any whole number… If the number is even, divide it by 2; if it is odd, multiply it by 3, then add 1. By repeating this procedure, sooner or later you’ll arrive at the number 4, which will give you 2, which in turn gives you 1, and then get a 4 again! No matter what number you choose, you’ll always arrive at the 4-2-1 cycle.”
Not all of the information is strictly math-based facts, either. For example, the site says “During any police lineup the suspects wear nos. 2 through 9 because it is considered too suggestive to make anyone display the no. 1!”
There are also links to puzzles, tricks, optical illusions, and much more information on numbers.
