comment How to calculate $\lim \limits_{n \to \infty}(1 +\frac{a}{n})^n$?
What definition do you know for $e$? Do you know the value of $\lim (1+\frac{1}{n})^n$?

comment Find members of this field.
To find -1 in $\mathbb{Z}_5$, recall that the symbol "-1" stands for the (unique) element which, when added to 1, yields zero. You only have five possibilities to check. (The problem of finding 1/3 in $\mathbb{Z}_7$ is similar.)
