# Why I cannot divide by 0

yea then if the numerator is a rational number
since the denominator is approaching zero it'll be positive or negative infintiy depending on the sign of the numerator

The limit, as the number of people I'm dividing cake for approaches zero, the number of slices approaches...
LOL
Blitz has a point, if we are taking the cake example, you can't do limits, this is a real life scenario.

Yeah thats the fastest way to answer it, for more proof and whatnot youtube has some videos for that
but the cake is a lie

cake goes to infinity

I just found to never run out of cakes
Wait, wouldn't you eventually end up with a cake that's untouched? Like, at the limit there won't be any people to give the cake to... (I don't think this is a very good analogy for why you can't divide by 0.)

The old fashioned notion of dividing a whole slice for N people is not going to do us good in this, we need to break the problem down to its core. When you are slicing a cake, you are taking and series of angles of a circles in parts and distributing them one by one. The procedure is the following: You take the whole 360 deg angle and divide it by the number of people you want to give it to, then you trace that much from the starting point around it, and give that much you traced to the first person. Then repeat until you got no cake left. So consider this:

You have 2pi of cake and need to divide it by one person. Ok: (2/pi)/1 = 2/pi, a whole cake. Here you go one person!

What about half a person? (2/pi)/0.5 = 4/pi or 2 wholes. Right? Wrong! You just go around once, and obviously the rest doesn't matter since you traced the whole, but for the sake of math we will trace a full circle again. The whole cake has been traced around anyway and the half person gets the full cake

What about a third of a person? Same you just go around and stop where you went around already, effectively making no difference.

What about Infinity? Same no difference. Whole cake.

Does this work for 2 people, you, a skeptical reader might be now wondering, now concerned about the nonsense I wrote. Well yes, idiot reader, it does work. Here is how: (2/pi)/2 = pi or half of a whole. So you give the traced amount to the first person and continue tracing (2/pi)/2 for the second person. Another half!

And so, quod erat demonstrandum

Edit: What happens if you try dividing by infinity:

my god
why would you have 2pi of a cake tho
Well assuming its a regular cylindrical cake
It should have 2pi*r^2*h of edible volume available.

3D is irrelevant when cutting the cake because of the subsection nature of the cut. If you have a 4D knife and cake on the other hand, then would play a role.

Why not?
This thread is a fathom away from plunging into the abyss of mathematics, I would like to execute a strategical retreat.
how did it get this complicated
I thought the answer was () (you divided the 0 in the middle and it splited into () )
Now that's what I call being tactful

Wow
