SUMS is having a MATHS RELAY this week. For those unaware of what a maths relay is, here’s a brief description: - Competitors form teams and compete against other teams to solve maths problems. -Problems are given to teams one at a time (so initially they only have Problem 1). Once a team solves the problem or pass on it, they are given the next problem. - The problems are worth varying points (usually the initial problems are worth low points, and generally increase in value as the problems get harder), and the team with the most points at the end, wins. - Each problem will contain a single answer (usually some number), no proofs will be needed (so guessing the answer may be a strategy, although usually this isn’t recommended). All of the problems will only require high school mathematics to solve, so don’t worry if you haven’t yet taken Advanced Vector Calculus or Lagrangian Dynamics. You won’t need them. However, some rules for this relay (note that these rules may change, in which case I will inform you): * Teams can have a maximum of 3 members (of course you can have less than 3 if you wish). Teams should also have a team name (if not, we will assign a name at the relay). If you form your team prior to the relay, we would prefer it if you notify us of your team and team name beforehand (by emailing us), as we then have less to organise on the actual relay day (which means a better run relay). If you wish to participate in the relay but are not in a team, email us and we shall put you in a team. If you wish to compete but you do not want to be in a team, that’s fine too, just make sure you tell us. Teams or individuals that turn up to the relay without prior notification are allowed as well, but please try to turn up on time. * Once you submit the correct answer for a problem, you are given the next problem. Alternately, if you are stuck on a problem, you may choose to skip it, and get the next problem. Skipped problems are not penalised (as in, no points are deducted), however you cannot return to the problem later. * You may have as many guesses as you wish for each question. Teams will not be penalised for incorrect guesses. * Your submitted guess should be written on the paper with the problem on it. You can only guess one at a time. If you wish to make another guess (after an incorrect one), you must return to your team table and write down your new guess (and cross out the previous guess). Anything else that you have written on the paper should be crossed out. * The relay will be held in New Law 026, this Thursday from 1-2pm (the usual place/time). The relay itself will probably take about 40 minutes. * There will be prizes! If you have any queries or you wish to enter, please email us (usydmaths@gmail.com). The more participants, the better! Hope to see you there! SUMS President
