As you can probably tell, I’ve been on a bit of a logic kick this week. And why not? Logic is one of the most useful forms of mathematics there is!
Wilfred heard that there is only one whole number between 2 and 200,000,000,000,000 which is a perfect square, a perfect cube, and a fifth power, and has decided to look for it.
So far he has checked out every whole number up to 100,000 and is beginning to…
An Unusual Number Problem

This was our challenge:
Use the numbers 7, 7, 7, 7 and 1 to create an expression that equals 100.
For this exercises you may use the addition, subtraction, multiplication and division operators along with…
Since the last number puzzle was enjoyed so much, I thought I’d pose another to give you a second opportunity to conquer one. This puzzle is similar in concept to the last one (except parentheses are allowed this time), so give it a shot!
How’d it go? Did you solve it?
You are given the numbers 8, 8, 3 and 3. With only the operations of addition, subtraction, multiplication and division use the above numbers to yield 24
I love this number puzzle because it is simple enough for the beginner and tricky enough to stump a mathlete. All you need to know is basic arithmetic!
So how about it? Ready to give it a try?
Ever so often I’m asked: why do you love math so much? And every time for a split second, I ponder a love that has become second nature to me. It’s not the equations, formulas, proofs or theorems. It’s something intangible. It’s in the process.
