stil Oct 07, 2006	more an exercise than tease
javaguru Jan 24, 2009	OK, how does this get a fun rating of 2.42? (The rating before I rated it.) Not only is this boring and tedious, but there's no explanation with the answer. Lame all around, yet apparently really fun...
Jimbo Apr 20, 2009	In the 100's column there will be 100 (300...399) In the tens column there will be 10 (330...339) In the units column there will be 10 (303...393) Total 120. Too easy to be a teaser.
