Move the 3, Triple the number (Posted on 2004-03-01) Difficulty: 2 of 5
If you moved the 3 at the end of a certain large number to the beginning, it would be the same as multiplying it by 3. What is the number?

Argh... another correction - minor this time.  The general formula is right the way I left it in my last correction.

It's just that I wrote last time that n=0 produces a solution that satisfies the equation made to model the problem.  That it satifies the equation but is not a valid solution because that would make X=0 and X wouldn't end with 3.  But now I look and realize X=0 DOESN'T satisfy the equation at all.  So we're all the merrier because we don't have to justify eliminating n=0 case with words.  The equation takes care of it.
