1 An excursion through mathematics and its history (In no particular order)(and some trivia) MATH DAY 2017 TEAM COMPETITION Made possible by
2 A quick review of the rules History (or trivia) questions alternate with math questions Math questions are numbered by MQ1, MQ2, etc. History questions by HQ1, HQ2, etc. Math answers should be written on the appropriate sheet of the math answers booklet. The answer to every math question will be either an integer (mostly positive) or the square root of a positive integer. Square roots of positive integers MUST be entered in the form m n where m, n are positive integers and n is square free. Examples: 12 should be entered as 2 3, 50 should be entered as 5 2, 3 98 as History questions are multiple choice, answered using the clicker. Math questions are worth the number of points shown on the screen when the runner gets your answer sheet. That equals the number of minutes left to answer the question. Have one team member control the clicker, another one the math answers booklet
3 Rules--Continued All history/trivia questions are worth 1 point. The team with the highest math score is considered first. Next comes the team with the highest overall score, from a school different from the school of the winning math team. Finally, the team with the highest history score from the remaining schools.

8 Demonstrating the points system For math questions there will be a number in the lower right corner. It will change every minute. Here I am illustrating with numbers changing every 10 seconds. Try to imagine 10 seconds is a minute. The first number tells you the maximum number of points you can get for the question. Assume a question is on the screen.
