I don't pretend to understand this very well myself but one very important quality of e is that if you graph y=ex on the number plane then the gradient of the tangent to the curve at any point is also ex
In terms of calculus this means that if
y=extheny′=extoo.
Also
This is a very important fact when dealing with continuous exponential growth and decay.
