is about the tasks package.

The rea­son for the cre­ation of the tasks en­vi­ron­ment was an un­writ­ten agree­ment in Ger­man maths text­books (exspe­cially (ju­nior) high school text­books) to or­ga­nize ex­er­cises in columns count­ing hor­i­zon­tally rather than ver­ti­cally. This is what the tasks pack­age helps to achieve.
