The problems in this competition comes from Náboj. This is a competition designed for teams of students that represent their schools. The whole competition takes 30 minutes during which the teams are trying to solve as many given problems as possible.


COMPETITION

At the beginning of the competition each team receives four problems. As soon as the team correctly solves all of the problems, it receives a new one. The solutions of the problems are usually numerical. The team that solves most problems correctly in the given time limit wins.


Participation in the competition is free of charge.


ABOUT THE PROBLEMS

Difficulty of the problems is appropriate both for students inexperienced in mathematical contests and for students who have already finished high school. This is achieved by arranging the problems in order of their perceived difficulty. The problems differ considerably from the routine school exercises which usually require only direct application of a given method: the problems require certain amount of inventiveness and ingenuity. Success in the competition does not depend on the individual abilities of the team members only but also on their efficient cooperation. Apart from enhancing imagination and logical reasoning our goal is to attract people to the endless beauty hidden in mathematics.
