Matchstick puzzles are always a fun challenge for observation skills and flexible thinking. In the image above, the equation 9 + 9 = 11 is formed from matchsticks, and of course, according to conventional mathematics, this is completely incorrect.
However, the rules are very simple: You can only move one matchstick, without breaking or adding any, to turn the incorrect calculation into a correct one.
It sounds easy, but not everyone can figure it out on the first try. Are you quick and sharp-eyed enough to solve this riddle? Try thinking for a few seconds before looking at the solution!
By moving just one matchstick, can the equation 9 + 9 = 11 be correct?
