Download rules of mathematical abaka

Mathematical abaka is a team game-competition for solving problems. All tasks are issued to solve all commands at once. The main scoring indicator in mathematical abstraction is the total number of points scored (including bonuses). In the case of equality of points for several teams, a higher place is taken by a team that has a larger amount of bonuses. With equality and this indicator, teams are considered to share seats.

 

Solving problems

Each team is offered 6 topics on 6 tasks in each topic. The tasks of each topic are given in order, from the 1st to the 6th (for example, the team will not accept the answer to the 4th task until it has answered the task 1, 2 and 3). Each task is given one approach (one attempt to pass an answer). If a team responds correctly to a task, it receives the task price, and if the answer is incorrect or incomplete, it gets 0 points. In some tasks, at the discretion of the jury, the price of the task can be divided equally between all possible answers, in which case each answer found brings the corresponding part of the price to the team. For each such task, this is indicated in its condition.

The price of the first task of each topic is 10 points, the second – 20, …, the sixth – 60 points. Thus, not counting bonuses, the team can earn maximum points for solving problems.

 

Main bonuses

Each team can earn bonus points:

  • For correctly solving all tasks ("bonus-horizontal") – 50 points
  • For the correct solution of problems with the same number in all topics ("bonus-vertical") – the price of the task with this number

Bonuses for the first solution

The first committees, which received a six-per-sidedbonus-horizontal and each of the six-sided verticals, receive their double size.

End of game

It take 90 minutes to solve the problems. The game for the team ends if it has run out of tasks or all the time allotted for the game has expired.
