## Ciphering

A school may enter as many students into ciphering as it wishes, but no students from the same school may sit next to each other. After three rounds, the top four teams will participate in the math bowl competition.

Each individual is given a booklet with one problem per page. In addition to the problem, each page will have space for scratch work, a block for answers, and a space for the individual's code. Improper code or lack of code will disqualify an answer.

All answers must be in **exact, simplified** form unless otherwise requested. All fractions must be reduced and all radicals must be simplified. Remember that 1 / √3 is acceptable, but 6 / √3 is not because it can be reduced to 2v3. Units are not necessary unless specifically requested, but if units are included, they must be correct.

Two minutes are allotted for each question. When students answer the question, they will raise their sheets above their heads for runners to collect. Four points are awarded for answering the question correctly within one minute, while two are awarded for answering correctly within two minutes.

An individual will receive an overall score, while the team totals will be used to determine who advances to math bowl. Each school's cipherers will be ranked by score and set in teams of four from the top downward; the four teams with the highest totals will compete in math bowl.

The individual from each division with the highest total score after three rounds will receive a trophy, but no points will be added to sweepstakes.
