So, I would say
5 elephants ≠ 5 cats
But context matters.
I would also say
5 mammals = 5 mammals
I will courageously assert: it depends.
"If 1/oo = 0, what if you add oo/oo = 1?"
What you got there is
extensionality and intensionality,
that extensionally X mammals is X mammals,
while, intensionally, it depends:
on the individuals.
Nice thing about language:
it's built into the words.
"In-di-vidual."

Nice thing about the English language:
There are separate grammatical categories for
what exists as distinct entities (count nouns)
and what doesn't (mass nouns).
Is the continuum a count noun or a mass noun?
(Not the best question. English ≠ math)
It seems to me that it crosses back and forth.
Points are definitely a count noun.
But the idea of a continuum seems
inescapably not.individuals.
Perhaps that count/mass dimorphism is
why the occasional poster rejects uncountability.
Well good sir,
mostly it's that firstly there's that
the "infinite limit" must concede that
it's actually infinite
and that
the limit is not only "close enough"
yet actually that
it achieves the limit, the sum,
because deduction arrives at that
otherwise it's no more than half,
and, not close enough.
Then there's
for division and divisibility,
the "infinite-divisibility" and
for this sort of "actually complete infinite limits"
the "infinitely-divided".
Then it's pretty much exactly
most people's usual notion of that
an infinitude of integers,
regular both in increment and in dispersion,
so equi-distributed and equi-partitioning
the space of integers, is
the same kind of thing when shrunk to [0,1],
the space of [0,1]
as by the same members, that it fulfills
extent, density, completeness, measure,
thusly that
the Intermediate Value Theorem holds,
then thusly
any relevant standard analysis about calculus
holds, or has forms that hold.
What it is is that at one point
I wrote non-standard field axioms for [-1, 1],
so, now the usual
"the complete ordered field being unique
up to isomorphism"
is a distinctness result
instead of a uniqueness result.
Then, another thing is about
a deconstructive account of complex analysis about
the very definition of complex numbers a + bi and
the definition of the operations upon them.
The thing is that division, for complex numbers,
the definition of division, can be de-constructed,
left and right,
so that now there are non-principal branches of
division, in complex numbers.
