This week’s puzzle is another deceptively simple one. But like a lot of apparently simple puzzles, this is a lot more difficult than it first appears. The challenge is to complete the nine sums below using common mathematical symbols. For each of them you need to make a sum that totals six. You have to treat the three numbers as separate numbers; there is no combining them to make two-digit numbers, so no 22 * 2 = 44.
1 1 1 = 6
2 2 2 = 6
3 3 3 = 6
4 4 4 = 6
5 5 5 = 6
6 6 6 = 6
7 7 7 = 6
8 8 8 = 6
9 9 9 = 6
To help you on your way, 2 + 2 + 2 = 6. As an additional puzzle, how many other ways are there of solving the “three twos” sum?
And if you want a real challenge, can you extend the sequence further to solve “three tens”, “three elevens” and so on? We have solutions using slightly more obscure mathematical symbols.
As usual you can post the answers as a comment on this website, reply to the post on Facebook, or retweet or reply on Twitter @quizmastershop.
