There are many ways to calculate the value of e. One way is to calculate the answer to the equation (1 + 1/n)n . As n gets larger and larger, the answer more closely approximates e to more and more decimal places. No repeating pattern of numbers has been found when calculating e.
e, like pi, is a mathematical constant that pops up in math expressions used in many different fields. e is used in calculations of logarithms, compound interest, probabilities, the behavior of quantum particles, and in many other applications.
e is named in honor of the great Swiss mathematician and physicist, Leonhard Euler (1707-1783).
