Without you (Posted on 2014-04-30) Difficulty: 4 of 5
1. N1=*u*
2. N2 =*u*
3. N1 not equal to N2
4. N1 x N2=u***u*
5. The letter u represents a certain digit.
6. All other digits are replaced by an asterisk (*).
7. No u in the partial products.
8. "x" in statement 4 is a multiplication sign.

Please restore the original numbers N1 and N2.

Bonus question : Eliminating the 7th condition, do we get additional solutions?
