comment Can I always embed a sequence into a function?
You can always define the function. You can apply L'Hospital's rule if the function satisfies the hypothesis of that rule.

comment Why are $n$-ary function symbols interpreted as $n$-ary operations and not general $n$-ary functions?
What would this accomplish? You can get away with the same thing by interpreting a relation that defines the appropriate subsets, but in general it is cleaner to not have worry about specifying the appropriate subsets.

You can let $A$ be a single element.

comment $t$-adic topology (on $\mathbb F_p(1/t)$)
The $p$-adics and their topology are a special case of ring completions and the Krull topology. I suspect this is as well, simply by choosing the appropriate ideal. en.wikipedia.org/wiki/Completion_%28ring_theory%29

comment Definition of a metric space: why $E\times E\rightarrow\mathbb{R}$?
No, the input is four real numbers $x_1,x_2,y_1,y_2$. The output is a single real number.

comment Definition of a metric space: why $E\times E\rightarrow\mathbb{R}$?
This is in line with my explanation. You take the distance from $(x_1,y_1)$ to $(x_2,y_2)$. These two inputs have a total of $4$ pieces of information, $x_1,x_2,y_1,y_2$, which you can think of as an element of $\mathbb{R}^4$ if you want.
