The document describes a math game called MathDate that uses a calendar and empty medicine bottles. Players take turns blindly picking bottles from a bag and placing them on numbers on the calendar, with green bottles adding and blue bottles subtracting those numbers. The player whose total is closest to the date wins. The document provides an example game where player 1 got a total of 16 and player 2 got 12, so player 2 won. It concludes that learning math can be fun this way and the loser does dishes.
