No winners for January Math Mania
There were just a few entries for the January Math
Mania contest and none of them had all the right answers.
Maybe with more time in Feburary, we'll get more entries
and more winners.
Ms. Math Mania, Ms. Amy Ruzicka, doesn't like
it when we don't get to give any Border's 10 gift certificates
to winners. Let's do better during February.

January Math Mania SOLUTIONS
The rules of "24" are very
simple: Use each of the numbers only once to form an expression
that equals 24. You may use addition, subtraction, multiplication,
division, and parentheses. Don't forget to follow the order
of operations!

check out Math Mania from April
2008.
