Jerry's equation 

Jerry's equation is based upon the concept of a type 2 error in statistical analysis. A type 2 error is thinking that a relationship is not failing when it really is. This is also known as a false negative or negative error.

He drove all the way to Charlotte to just have her tell him she was cleaning the house and he is still with her. Homeboy better wake up to Jerry's equation.

Richard’s Inverse Equation 

States that the confidence in one’s Penis size relative to its physical size is inversely proportional to “big dick energy” levels

“Yeah his dick was on the smaller side but that didn’t stop him from rocking my world, it amazing how confident he was in himself.
Yeah that’s that “Richards Inverse Equation”

Albert Einstein's Ejaculate Equation

In 1945 Einstein came up with the idea to start jerking off before a presentation to clear his mind. It can also be used for students when they are taking a test to help figure out the answer

Dude I just used the Albert Einstein's Ejaculate Equation on that test and made a 100

Equation Sheet 

An entire engineering textbook miniaturized to an 8.5 x 11 sheet of paper.

I need stereoscopic glasses to differentiate between the red and blue layers of notes on my equation sheet.

Sylvester Equation

An equation that tells you exactly how many beers you would need to drink to make a conscious decision to sleep with a girl. Person using the equation must be sober.

10 - X = # of beers

where '10' is the maximum 'hotness' score a girl can recieve, 'X' is the score given to the girl (1-10). The subtraction yields the number of beers one needs to consume.

*note: a beer can also be replaced by a 1oz. shot or mixed drink equivalent to one ounce of alcohol (40% or greater)

(taking place at local bar/club/party)

GUY1: Hey man what do you think of that girl over by the bar?

GUY2: Man, I'd give her a 4 outta 10

GUY1: Yea she does look pretty beat. Well according to the Sylvester Equation I'm gunna need 6 beers before I try to get any.

simultaneous equation 

equations involving two or more unknowns that are to have the same values in each equation.

If an equation has two unknowns, such as 2y + x = 20, it cannot have unique solutions. Two unknowns require two equations which are solved at the same time (simultaneously) − but even then two equations involving two unknowns do not always give unique solutions.
This gives us a 'simultaneous equation'
