--The method of calculating on your fingers the possible number of hours you can sleep after being up later than you wanted.--
Sleep Math is usually only done when you know you have to get up early, wished you could just sleep in, and are stressing because you're afraid you might not get enough sleep.
With a normal, not exhausted brain, you could probably do this math in your head. However, since you are tired you have to go back to how you did math as a child, counting on fingers.

(Couple intended to go to bed 'early' this particular night, and instead, stayed up way late talking & watching old episodes of The Sopranos.)
After finally brushing teeth and getting ready for bed, girl notices guy using his fingers to count something, like this 30+ man is all of sudden a 5 year old--
Girl to Guy--"You must be doing Sleep Math"

When the teacher asked little Timmy how he got his homework done so fast, Timmy replied,
"I went home and did some crystal math."

A form of applied math usually learned in college (but outside of the classroom) that involves figuring out just how many beers from a case are rightfully yours. When splitting a case (commonly a 30 beer case of Keystone Light or Busch Light) with friends, one will usually perform a quick mental equation of the portion of the case that belongs to them.
It's been theorized that Case Math is the only form of math that's actually worth two fucks.

Ed: Just picked up a 30 rack! You, Alex, and I are splitting it.
*you and Alex quickly perform some mental case math and both deduce quickly that each guy gets 10 beers*
OR
*Ed is trying to give a girl a beer out of the shared case, in hopes of getting her drunk and hooking up with her.*
Ed: Hey, I'm gonna give this girl a beer from our case, cool?
You: Sure, but that comes out of your beers, me and Alex are still drinking our 10. And you'd better close, too.
