I have discovered this problem and would love to solve it but can't get into it. I have been told there are at least three different solutions to it. Each letter represents a number between 1 and 26.
N x N = M
I + C = W
Q + J = E
S x S = A
D + F = R + T
B + U = K
O x S = V + O
G x G = Z
P x N = H
Q x Q = X + L
C + L = Y
D + R = Z + P
F + T = (X*2) - A
B is lower than U
