What you need to know about e

e is a mathematical constant approximately equal to 2.71828.

It is the base of the natural logarithm and is used in many mathematical formulas.

e is an irrational number, which means it cannot be expressed as a simple fraction.

Its decimal representation goes on forever without repeating.

History of e

e was first discovered by the Swiss mathematician Leonhard Euler in the 18th century.

Euler was studying the growth of populations and realized that the rate of growth was proportional to the size of the population.
