What is Math League?

Math League is an opportunity for students in any grade to expand their math problem-solving skills. Six contests—the first beginning in October—challenge students to use their creativity, common sense and math skills (and occasionally a calculator) to tackle a variety of atypical math problems.

Do you have what it takes?

Old tests and their answers are available in the Media Center. Stop in, look them over, give them a try. Discover the fun of math! In the meantime, try a couple of sample questions:

1. When the first 1995 positive odd prime numbers are multiplied together, what is the units digit of the product?

2. The School of Hard Knox belongs to a six-school league in which each school plays four games with each of the other schools. No tied games ever occur, and the other five schools finished this season having won, respectively, 20%, 30%, 35%, 60% and 80% of the league games they played. What was The College of Hard Knox winning record in the league this season?

(Answers:

1. Every odd multiple of 5 ends in 5.

2. At season's end, each team, on average, has won 50% of its games; so the sum of all six winning percents is always 6(50%) = 300%. the sum for the five schools whose records were known was 225%, so Hard Knox's winning record was 300% - 225% = 75%.)
