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
