Are E numbers natural?
Many E numbers are naturally occurring substances, such as vitamin B1 (E101) and even oxygen (E948).
What is the history of e?
The number e first comes into mathematics in a very minor way. This was in 1618 when, in an appendix to Napier’s work on logarithms, a table appeared giving the natural logarithms of various numbers.
How is e used in the real world?
Euler’s number, e , has few common real life applications. Instead, it appears often in growth problems, such as population models. It also appears in Physics quite often. As for growth problems, imagine you went to a bank where you have 1 dollar, pound, or whatever type of money you have.
What are E-numbers made of?

Who invented Euler number?
It was that great mathematician Leonhard Euler who discovered the number e and calculated its value to 23 decimal places. It is often called Euler’s number and, like pi, is a transcendental number (this means it is not the root of any algebraic equation with integer coefficients).
