Hello, Stew99!

I'll format the problem.

. . Maybe others will be tempted to try it.

Quote:

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 . . .
