Rules of Engagement • Please turn off all cell phones while Math Bowl is in progress. • The students participating in Rounds 1 & 2 will act as checkers for one another, as will the students participating in Rounds 3 & 4. • There is to be no talking among team members once the round has begun. Any pairs caught talking, even between questions, will be ejected from the competition.
Checkers are more than welcome to take a chance that the answer their teammate gave is also correct, though it doesn’t appear as a possible answer. However, keep in mind that if the answer is in an unacceptable form or otherwise incorrect, points will be deducted from the team score according to how many points would have been received if the answer was correct. (5 points will be deducted for an incorrect first place answer.)
Checkers, please remember that multiplication and addition are commutative. • Correct solutions not placed in the given answer space are not correct answers! • Rationalize all denominators. • Reduce all fractions, unless the question says otherwise. Do not leave fractions as complex fractions. • Use only log base 10 or natural log.
It is only necessary to write an equation when asked for an equation or a function. • Answers of the form are acceptable, unless both answers are rational. • Use interval notation for domains and/or ranges. • When units are given in the problem, units are required in the answer. • Good luck, and most importantly, have fun!
