September puzzle answers

8 kids answered all Math Mania puzzles

The 2007-08 Math Mania got off to a good start in September as eight kids answered all the six puzzles correctly.

All of the kids who got all the answers correct were from St. Louis.

They are (in alphabetical order):

Jenny Berghoff, Kate Evold, Paul Denham Kieffer, Joshua Lee, Addison Leong, Shun Tomatsu, Veit Ulrich and Marie Warchol.

Congratulations to all those who got all answers correct.

The kids who did best with these unusual puzzles probably made use of a calendar, more than a calculator to figure out the answers.

With so many winners, Young Saint Louis.com upped the number of $10 Border gift certificates from three to four. Then, YSL.com put the winning names in a hat and selected the four at random.

Certificates winners: Kate Evold, Addison Leong, Viet Ulrich and Marie Warchol.
