I’m 20 today!
There are 20 matchsticks arranged in the shape of the word TWENTY below. Your goal is to move just 4 matchsticks to make an expression which, when evaluated, equals 20.
Like every year, it’s hard to guarantee uniqueness. I think it likely is unique, but even if it’s not I’d be interested to see what creative solutions you can come up with. If you want to check your answer against mine, the MD5 hash of the expression I have, with no spaces, is f7195be5dde9a77f21175cd8049ed557
