The limit of the expression (1+1/n)^n as n becomes infinitely large, and the base of natural logarithms. An irrational number, approximately equal to 2.71828182846. e is also known as Euler's number, for Leonhard Euler.

E
a number that, when raised to the x power, is the derivative and antiderivative of itself.
d(e^x)/dx = e^x, sucka.
?(e^x)dx = e^x + C. Holla at calculus, biotch.
e can be represented by the infinite series 1+1/1!+1/2!+1/3!+1/4!.....
e is the base for natural logarithms.
the e root of e has a higher value than any number in the form of "n root of n." (approximately 1.44467)
e to the square root of negative pi (an imaginary number) amazingly equals -1, a real number.
