0 Guest Posted May 21, 2009 Report Share Posted May 21, 2009 what are you supposed to do? you have to move just one matchstick in a way that the mathematical sum is true ( note that the letters given below are roman numericals eg 'I' is used for '1' ) eg. III(3) + I(1) = IIIIII (6) sol---- IIII(4) + I(1) = IIIII(5) I moved one stick from 6 making the no. to 5 and brought it to 3 making it 4 see the attachment for actual puzzle or i have written it below IIII + II = III Quote Link to comment Share on other sites More sharing options...
0 Pickett Posted May 21, 2009 Report Share Posted May 21, 2009 (edited) Since the OP doesn't specify HOW this needs to be done, I'm going to take the super easy way out for now: Simply move any one match from the |||| on the LHS and put it on top of the equals sign to give you: ||| + || ≠ ||| So, 3 + 2 does NOT equal 3...voila, I moved one match stick to make it a completely valid mathematical equation.

0 Guest Posted May 21, 2009 Report Share Posted May 21, 2009 change it so its: 5 - 3 = 2 (in matchstick form) Quote Link to comment Share on other sites More sharing options...
0 Pickett Posted May 21, 2009 Report Share Posted May 21, 2009 change it so its: 5 - 3 = 2 (in matchstick form) Since the original was |||| + || = ||| and you're only allowed moving 1 matchstick...I don't see how you can get ||||| - ||| = || out of that (you'd have to move 2 matchsticks...1 from the plus to make it a minus, and one from the RHS to make it ||)... but you can get ||||| - || = ||| (5 - 2 = 3)...so, you just had your numbers flipped...so good answer!
