A fundamental disregard for sets and their importance in higher mathematics.

cry harder, number boy.

Clever and I get the joke and it made me smile. If I recall my biology from 20 years ago I think the cell makes duplicates of its chromosomes then splits apart. So you have two cells inside one membrane that separates, 2 / 1 = 2. The way I first thought about it was one cell splitting in half, so half goes to one cell, the other half with the other, 1 / .5 = 2.
In short, I think the math works out fine, but the language you use to describe it can lead to comedy gold. You could say cells reproduce by division? I don't know, I'm not a biologist or mathematician. I'm a toilet poster.

No comments about Amitabh Bachchan's use for meme. Well it should have been a long time coming, I'm glad that it's now here.

Bollywood itself is a meme 🤭. Just watch their version of The Matrix. Dude starts singing with "Trinity", like wtf!??
-
Lol it gets wtf long before he starts dancing with trinity.

The sets in [partition] P are called the blocks, parts, or cells, of the partition.
The number of cells in partition is >= 1.

That's the problem whenever math meets physics: the former wins in the theory, but in the real world physics always triumphs:-).

And mathematicians divide by multiplying!
In formal definitions of arithmetics, division can be defined via multiplication: as a simplified example with real numbers, because a ÷ 2 is the same as a × 0.5, this means that if your axioms support multiplication you'll get division out of them for free (and this'll work for integers too, the definition is just a bit more involved.)
Mathematicians also subtract by adding, with the same logic as with division.
this is true... except when it isn't.

Yeah I should maybe just have written
Right. The cells are dividing in half, which would be represented in math form by 1/0.5 = 2. Dividing by one half is the same thing as multiplying by 2, and division in general is really just a visually simplified way to multiply by a fraction of 1.
Any time you divide by some fraction of 1, you will necessarily end up with a larger number because you're doubling that division which reverses it back into multiplication, much in the same way as a negative x negative = positive. If that makes sense.
A mathematician would not be bothered by this. A high schooler taking algebra I might be though, if you phrased it the same way this post did.
a/b is the unique solution x to a = bx, if a solution exists. This definition is used for integers, rationals, real and complex numbers.
Defining a/b as a (1/b) makes sense if you're learning arithmetic, but logically it's more contrived as you then need to define 1/b as the unique solution x to bx = 1, if one exists, which is essentially the first definition.
That's me, a degree-holding full time computer scientist, just learning arithmetic I guess.
Bonus question: what even is subtraction? I'm 99% sure it doesn't exist since I've never used it, I only ever use addition.
The example was just to illustrate the idea not to define division exactly like that
Cells: 🫣🫨😢
