In many countries, in order to celebrate Christmas, shops sell Advent Calendars. These are 'calendars' with something special for every day of December up to Christmas; this is usually a chocolate treat for example.

As this will be my first December on Brilliant, I have decided to create an advent calendar with math problems instead! The problems will be of varying difficulty. I will try to post the problems on the previous day to account for the time zone difference.

Have fun and enjoy solving the problems.
