Challenge 24 for January Math Mania

The January Math Mania puzzles return to a familiar format as we start the 2009 year. You'll arrange the four numbers with appropriate math functions to achieve the common answer of 24.

Ms. Math Mania is Ms. Amy Ruzicka, who's been creating the Math Mania contest for the last few years. If you've entered previously, you know she likes to use a variety of puzzle formats to entertain you.

For January, she has six questions with sets of four numbers in each one.

Your job is to use symbols for addition, subtraction, multiplication, division and parentheses between the numbers to make the answers that each total 24.

The rules for entry into Math Mania remain the same. Competition is open to St. Louis area kids 8 through 13.

If you get all the answers correct, you are eligible to win a $10 Border's gift certificate.
