How much pizza is there in my pizza?

Hey guys!  Here is my submission for today’s daily create.  I was super excited about this one today, and then things got hectic and I almost ended up forgetting about it!  As a disclaimer: I did not invent this, I just drew it.  I actually have a shirt with something similar on it.  I have always liked silly math expressions, and this is one of my absolute favorites.  Hope you all enjoy!

The actual creation process for this was super duper simple.  My phone died right when I was about to snap the picture, so I had to use the Photo Booth app on my Mac.  The only editing I had to do then was to use Gimp (which I already had open for something else) to flip the picture horizontally.  The motivation for this was even simpler: for some reason I have been thinking about pizza all day.
