What number is $111$?

comment Weird Calculus problem
What do you mean by $f^2(x)$? And when you say "$g$ is a differential of $f$", do you mean $f'=g$?

By endomorphism, do you just mean "permutation"?

This is a perfectly legitimate question about the process of mathematical research.

comment A closed form for $\sum_{i=1}^{n} \prod_{k=1}^{i+2} (3k+2)$
The last term in this sum has $n+1$ factors each greater than or equal to $2$, so $Z(n)>2^n$ and therefore cannot be expressed as a rational function in $n$ (it cannot be written using only $+$, $-$, $\cdot$ and $/$).

comment Where do the topics covered in Lewis Carroll's 1896 book “Symbolic logic” fit in the modern mathematical curriculum?
I can't understand why this has 3 downvotes and a close vote in $20$ minutes, but it is true that your question is unclear. You have the book right there - you know what's in it. So what do you mean by the curriculum?

comment The nature of infinities
I don't think this is what the OP meant. It's clear from their preamble that by "infinite numbers" the OP meant infinite cardinals, not just large real numbers.

comment invert the triangular coin setting in minimum no of steps
I tried to format your formula, could you check I got it right? If so, the formula appears to be badly written, since it seems you're taking the minimum of a single number.

comment Refining my knowledge of the imaginary number
@JohnFernley The OP's confusion is in large part coming from not knowing that there's more to construction an algebraic structure than the simplistic approach that his teachers gave him. I know I spent a long time in the dark because I didn't realize that.

comment Refining my knowledge of the imaginary number
@JohnFernley Sometimes vagueness is okay, because it's obvious how to fill in the gaps. Here though, it really isn't, which is why it took so long for complex numbers to be accepted. It's not clear that you can just make up a new number until you really sit down and think through what that means.

@user72694 That doesn't make the question any more answerable, though.

comment The nature of infinities
This seems more like poetry than philosophy. Your question to me seems like "is this is a nice metaphor for infinity".
