## Homework Statement

In writing the definition of ##e## i.e. ##e=\displaystyle\lim_{n\rightarrow\infty}(1+\frac{1}{n})^n##, why do we denote the variable by 'n' despite the fact that the formula holds for n∈(-∞,∞)? Is there any specific reason behind this notation i.e. does the variable have anything to do with positive integers (which we normally use 'n' for)?

## Homework Equations

##e=\displaystyle\lim_{n\rightarrow\infty}(1+\frac{1}{n})^n##

## The Attempt at a Solution

I see no clue as to why is this so.
