Relational Algebra

Conversation between a friend and I:

Seth: You finished databases?

Me: No, I finished algorithms. I'm working on databases right now. I wonder if the instructor allows variable assignments. Seriously look at this shit. It gets ridiculous.

Seth: ...What symbol is that?

Me: Which symbol?

Seth: ...All of them.

Me: That one's capital Π. It represents the projection operation.

Seth: It looks like Egyptian hieroglyphics to me.
