Each Friday morning I post a riddle to get you to think outside the box and exercise your brain. If you are stumped, share it with a friend or colleague and see if you can figure out the answer together.
This week’s riddle forces you to think like a kid. I hope you enjoy it and share your guess below as a comment. If you don’t see your comment posted right away, don’t worry, I want to give everyone a chance to guess.
This week’s brain teaser:
If eleven plus two equals one, then what does nine plus five equal? Explain your answer.
