Matchsticks – A Visual Riddle or Two
The object of this puzzle is to re-arrange 1 matchstick to create a true equation. You can get a box of matchsticks, toothpicks, pencils, etc… and set them up as shown below. You could just as well figure it out in your mind’s eye — but I think you’ll appreciate this mental exercise more with the physical aspect.

OK… how about one more puzzle before ending this post. This is an original creation of Peter Grabarchuk called “Matchstick Checkerboard”:
There are five squares formed with 20 matchsticks, as shown in the illustration below.
Goal: Move three matchstick to get nine squares. The matchsticks’ overlapping or breaking and “loose ends” are not allowed.
