Should I assume that the LH side of the equation is (MOM)squared, or M*0*Msquared??
Come on... it's not that hard. And to clarify once again, that is the letter 'O' which can be any digit, not just zero.
Well, I have the answer. But is there a less tedious solution than working through the multiplication digit by digit?
Obviously if M and O are set, then the other values are decided. The smallest six-digit square with different digits is 323^2. The largest is 989^2. There are also things you can notice like M can't be 5 or 6, so that narrows things down.
