Hello, Stew99!
I'll format the problem.
. . Maybe others will be tempted to try it.
I've made some observation . . .Use the digits 0-9 exactly twice.Code:A B C × D E F - - - - - G H I J K L M N P - - - - - Q R S T U
Assuming a number may not begin with zero: .$\displaystyle 0 \:\neq \:\{A, D, G, J, M, Q\}$
Also, neither $\displaystyle C$ nor $\displaystyle F$ can be zero.
. . Otherwise: .$\displaystyle I = U = 0$ ... and we'd have three 0's.
$\displaystyle \text{Moreover, }E \neq 0\;\cdots\;\text{ else }J=K=L=0$
. . Stay tuned . . .
