How fast do Father Christmas and Knecht Ruprecht have to travel in their sleigh to deliver all the presents in time? How much water will fit into the two buckets that are ready to extinguish the Christmas tree? And when will the snowman be finished if the children continue at their current pace?
This unique Advent calendar shortens the waiting time for the big celebration day by day with two original and tricky maths problems - sometimes purely logical, sometimes strictly mathematical, but always to be solved without expert knowledge. Sometimes it's about the Holy Couple on their way to Bethlehem, sometimes about Father Christmas, a priest who likes to drink, the Christmas tree or Grandma Blümel and her famous cinnamon stars.
When Christmas Eve finally arrives, you can not only look forward to beautiful presents and a merry Christmas, but also to having become a little fitter again in maths.
An exceptional Advent gift for clever students aged 16 and over and adult maths fans.
