A very rare form of math only used on a Friday and/or Saturday night when all of your friends who dont have a job want to party, sadly, without out the money to carry out such goals. It will only come into play when your plans are 'have a chill night with a twelve-pack with yourself or one other person' any other plans that you might have are exempt from ever having to use beer math.

HOW TO USE BEER MATH

One: you take the number of people that are going to show up adding possible no-shows or the classic 'unexpected's'.

Two: you roughly determine how much each person will have depending on serval factors, such as the time of day, the persons mood, the persons girlfriend (whether or she approves of drinking) the night before, (whether or not a possible hangover is still very much effective) so on and so forth.

Three: you then compare that to the number of beers you have total assuming of course you have no money to buy more. By calculating this equation you can then figure out roughly how many beers you will ultimately have drank by the end of the night.

Example;

~6 people
two will only drink 2-3
the rest will have 6 or more

Divided into 30 beers

= a shitty Friday night.
