A number which all mathematicians can agree does not exist in math, but one which we put into equations just for the sake of argument and because it is so much fun.
"The solution to this equation is an imaginary number."
"So there is no solution?"
"Well, no, but I found it anyway."
An imaginary number is used in pointless math equations that do nothing but find another number. They are the reason for bad grades in math classes. Imaginary numbers have no real significant value except that you get a grade for something that is fake. Imaginary numbers come in letter form just to piss everyone off. They are the drunk girl at the party in the number world.
Aaron: I love imaginary numbers because I'm delusional.
Justin: Shut the fuck up. they are fake and you are high!!!
A number that can be written in the form a+bi, where a is zero and i is the square root of negative one
Examples: 3i, -2.8i, 5000i, etc.
