I'm sure everyone here has seen one of these things some time or another. Where you're given something like... SEND +MORE ______ MONEY ...and then you have to figure out what each letter represents as a number in order to make the solution make sense, and no two letters can equal the same number, and no number in front can equal zero. This particular gram that I posted I already know the answer for, but is there a specific way to solve these? I was thinking about using a systems of equations somehow, maybe... 1000s + 100e + 10n + d + 1000m + 100o + 10r + e = 10000m + 1000o + 100n + 10e + y. ... however I'm not sure how I'd get enough other equations to substitute! There's got to be an easy, mathematical way to do these. Anyone got some ideas?
