Time for a pop quiz.

Professor Bob Mignone, the chair of the Department of Mathematics, has been a professor at the College of Charleston since 1981.

During every class period, he uses two pieces of chalk.  There are 12 sticks of chalk in each box and 25 boxes in a case.

Assume he teaches at least one class per day during a semester. Not counting summer school, how many cases of chalk has he used during his College of Charleston career?

Time’s up!  Please put down your pencils.

Now class, please pay attention to the video above as Mignone explains why he wears his love of chalk on his sleeves — sometimes, literally.
