XXlll/Vll different to l

I couldn't find the simbol Different to, so I just took one match from the result and put it diagonal on the =. The result is a truth.

Yes, but you have to move two matchsticks.

simply take one matchstick from the bottom # making it six and move it to the top making that # 24 then 24 / 6= 2

I got it...how about XXXI = XXXXI! I know I moved a whole bunch of matchsticks...but 31 does equal 41...if you round the right side down by 10! I love this kind of brain teaser...give me more! I am going to use pi = 22/7 or something close to that in all my calculations from now on!

What about XXI + I / VI = II



What's wrong with that solution?

It has more than one answer, however the one posted, I would declare incorrect (though cute), compared with these answers: xxiii/vii > ii <--- OR ---> xxii/vii != ii These are exactly correct answers. 23/7 does NOT equal pi even if it matches the first 2 decimal places. No math teacher in the world would give that a correct answer. I'd give half credit for the try

I think the whole point of that was that the answer was clever. there are other ways to solve it of course, but I'd definitely say that making it equal pi (to 2 decimal places) definitely took the most thought. Of course everyone who didn't get that answer is angry and is just fuming over the fact that they aren't as clever as the person who came up with the problem.

The fact that 21 + 1 / 6 does not equal 2.
