On Friday I set this puzzle…
Imagine that the following equation (5 – 2 x 501=802) has been made from matchsticks….
What is the smallest number of matchsticks that can be moved to make it correct? Oh, and you are not allowed to move one to the equation sign to create a ‘not equals to’ sign.
If you have not tried to solve it, have a go now. For everyone else the answer is after the break.
In fact, you don’t have to move any matches. Just hold the equation up to a mirror…..
Did you solve it? Any other answers?
I have produced an ebook containing 101 of the previous Friday Puzzles! It is called PUZZLED and is available for the Kindle (UKhere and USA here) and on the iBookstore (UK here in the USA here). You can try 101 of the puzzles for free here.
