I don't pretend to understand this very well myself but one very important quality of e is that if you graph $$y=e^x$$ on the number plane then the gradient of the tangent to the curve at any point is also $$e^x$$

In terms of calculus this means that if

$$\\y=e^x\;\;then\\

y'=e^x\quad too.$$

Also

This is a very important fact when dealing with continuous exponential growth and decay.
