>so a series is simply a number where the approach to summation is the defining quality?
yes

https://en.wikipedia.org/wiki/Series_(mathematics)
>For any sequence { a n } {\displaystyle \{a_{n}\}} \{a_{n}\} of rational numbers, real numbers, complex numbers, functions thereof, etc., the associated series is defined as the ordered formal sum...

> and a function is simply an algebraic transformation that can take any value?
no a function from sets [math] X [/math] to [math] Y[/math] is a set of ordered pairs [math] S=\{(a,b) \mid a\in X, b\in Y\} [/math] where [math] (a,b)\in S [/math] and [math] (a,c)\in S[/math] implies [math] b=c [/math] (one output for every input)

there doesn't have to be any obvious algebraic transformation to it, something like [math] \{(0,1), (\pi, 10)\}[/math] is a function too

>if you look at it like you do the whole discussion is kinda pointless since then no numbers "exist"
that's why i said physically exist, which is the claim i was replying to

>The square of 2 is used, in the A series of paper to give an example. Therefore, it exists.
this is not clear at all, please elaborate

why conflate anti-(fake climate science) with anti-science? they're two different things

i don't see the trump administration denying gravity or anything like that
