# How did difficult math like algebra come about

Written by Alex Birrer (Canton School Obwalden Sarnen), Werner Hartmann (former Canton School Baden)

The Munterbunt collection of exercises offers pupils and teachers access to a collection of mathematics exercises at upper secondary level (e.g. grammar schools or vocational schools). The tasks arose as part of the former web-based platform Munterbunt (Remo Meier, Sam Zürcher, Raimond Reichert, Alex Birrer, Werner Hartmann, from 2001). The tasks and the associated solutions do not claim completeness or didactic balance, but rather serve pupils and teachers as a source of ideas and an opportunity to practice. The tasks are available free of charge for non-commercial use.
