How can you explain Euler's number to a layman?

Answer 1

Greetings! Lets clarify this some, shall we?

I believe Euler's number was create by Leonard Euler because he was the first one to notice that the natural logarithmic function possessed an inverse, which then created y = e^x.

The letter 'e' was created after his last name Euler, but lower case.

I hoped this helped a bit!
