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 If $A,B\in M(2,\mathbb{F})$ and $AB=I$, then $BA=I$
The downvote was from me. Though what you have written is mathematically correct, it does not answer the OP's question as stated.

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.)

comment functional equation uniqueness $f(x^{2})= f(x)^{2} $ in $\mathbb{C}$ and $f(x)+f''(x) = 0 $ in $\mathbb{C}$
@ccc: the problem statement requires that $f$ be holomorphic.
