The next edition of the Mathematics B-day will take place on November 13, 2020. 

The Mathematics B-day is a mathematics assignment for teams of three or four students published annually by the Freudenthal Institute of Utrecht University in the Netherlands. The teams work on an assignment - a very open ended problem situation - in which mathematical problem solving and higher order thinking skills must be used to solve the problem. The emphasis is on mathematical problem solving, conjecturing and proving. The result of the assignment is a written report. In the Netherlands, Belgium (Vlaanderen), Germany and Slovakia teams can also participate in a national competition, but this is not mandatory.  

Mathematics B is the mathematics needed for technical studies and studies in science and mathematics at university level; its core component is calculus.
