While college life is great and way better than high school, there will still be some problems you can't avoid. Sorry. But we've got a few tried-and-true mathematical solutions to help you out.

When can I dump my orientation friends?
Most college kids handle making friends during orientation like they would a turn on Supermarket Sweep, grabbing as many as possible in a short amount of time. Thanks to this smash-and-grab mentality, you may find yourself with a crew of friends you don't really like. Don't worry, orientation friends can be swiftly tossed aside once you meet real friends in the weeks to come.

How many pizzas should we order?
The food in the dining hall is gross. It just is. But with these four words you can rise above the foolish masses and become a beacon of hope for all within earshot: "Let's just order pizza." Now you've got to figure out how many pizzas to order. Here's how:
1. Tell everyone to hold up fingers for how many slices they want.
2. Add up all the fingers, and figure at least two more for some guy who is going to show up and want in. Now round up to the nearest multiple of eight (those are numbers like sixteen, twenty-four, thirty-two for you comm majors). That's how many slices you need.
3. DON'T GET AHEAD OF US.
4. Divide by eight. This is your "base" number of pies.
5. Add one "safety pie" for good measure.

Should I put myself into a situation in which I need to do real math in college?
