I have problems understanding why e is such an important number in the world of mathematics. The number pi ,for instance, equals the area of the unit circle and is the ratio circumference/diameter. Why exactly is e that important?(adsbygoogle = window.adsbygoogle || []).push({});

I know that e is the base of the natural logarithm, but is this just by chance and definition? Could it just have been any other number?
