What is e?
e is a mathematical constant and “natural number”.
Approximately equal to 2.71828, it has no end to the number of decimals (similar to the number pi).
e is calculated as 1 + 1/1 + 1/(1 x 2) + 1/(1 x 2 x 3) + 1/(1 x 2 x 3 x 4)…, with the pattern repeating (of adding an additional fraction of 1 divided by all the previous numbers multiplied together) until infinity.
e is often also known as Euler’s number of Napier’s constant.
How is e to the exponent calculated?
e to the exponent is calculated by multiplying e together the number of times of the exponent.
e to the exponent 3 is simply e x e x e, while e to the exponent 12 would be e x e x e… with a total of 12 e’s being multiplied together.
