She missed an operator (Posted on 2019-02-06) Difficulty: 3 of 5
Doing her homework Jane evaluated xy as a concatenation of two 3-digit numbers instead of a product x*y, thus obtaining a result n times bigger than the correct one.

Knowing that n is an integer find all possible solutions fitting the above fact.
