Yo dawg, we heard you liked math

You cannot divide by zero.

[Night]

Aww I thought it was going to be an intellectual joke.

I actually really like math.

Also if you're interested, here is why you can't divide by 0.

Well division is pretty much subtracted, just multiplication is like addition.
For example 10 divided by 2 really looks like this:
10 - 2 = 8
8 - 2 = 6
6 - 2 = 4
4 - 2 = 2
2 - 2 = 0
See we did that 5 times. 10 ÷ 2 = 5

Now lets say we divide 10 by 0
10 - 0 = 10
10 - 0 = 10
10 - 0 = 10
And so on and so on and you get it. It goes on for infinity.

So why isn't 10 ÷ 0 = ∞

Well first of all Infinity isn't a number. It's an idea.
And then we have this.
Ok, lets break the rules
1 ÷ 0 = ∞
well then
2 ÷ 0 = ∞
So then you get this
1 ÷ 0 = ∞ = 0 ÷ 2

And 1 ≠ 2

therefore, you can't divide by 0.

Actually makes more sense coming from infinity. I had trouble with dividing by zeros (division in general when it came to small decimals) until a teacher of mine gave a visual, which was kinda common sense...

[тωιѕтє∂]

Here's a more simple explanation:

So 10 / 2 = 5, because 10 split up equally into groups of 2 is 5 for each one.

But for 10 / 0, you have no groups to split it up into. 10 has nowhere to go. It cannot be stuffed in nothing, it cannot be split up in nothing. It is impossible.

I think the answer would be -10, not infinity, if that makes any sense.

[Miab419]

Why negative 10?

[тωιѕтє∂]

I dunno. Something have to be done with the 10, or the world explodes. This is my best guess.

[Miab419]

The answer is 42

khan academy has a few videos on this topic https://www.khanacademy.org/math/trigono...eterminate

if you divide any number by smaller and smaller positive numbers (x/1, x/0.1, x/0.001...etc) the amount represented by the fractions becomes larger and larger, so if you follow that pattern, x/0 should be positive infinity. but if you divide x by larger and larger negative numbers (x/-1, x/-0.1, x/-0.001...etc) the pattern suggests that x/0 should become negative infinity, so that seems like a contradiction

another contradiction is this: assume that (x/y)y=x example:(2/3)3=2. then assume (x)0=0 example: (3)0=0.

given: x =/= 0.
set (x/0)=(k)
multiply both sides by 0: (x/0)0=(k)0 <-- (x/0)0 should be equal to x according to "(x/y)y=x", and (k)0 should be equal to 0 according to "(x)0=0"
simplify: x=0
^x can't equal and not equal 0 at the same time, so either one of the two assumptions made earlier were wrong, or you can't divide x by 0 when x =/= 0.

you can divide 0 by 0 though.

set 0/0=k
multiply both sides by 0: (0/0)0=0(k)
simplify: 0=0k, 0=0

so k, or 0/0, could be any number and the math would still be correct. so 0/0 is indeterminate.

Quote:I think the answer would be -10, not infinity, if that makes any sense.

10/-1 is -10. (there are negative ten "negative ones" in ten.) 10/0=? is asking- if 10 were to be divided into a number of pieces with each piece equaling 0, how many pieces would there be? so infinity makes more sense, because you can break off an infinite number of 0's from 10. (but then 10 would never be broken up, so dividing by 0 doesn't make any sense)

[тωιѕтє∂]

Makes sense.

If you have to learn this shit in high school I'm screwed.

[Thade_Chan]

You don't have to, it's just interesting to contemplate. But, I've tried and the calculator just said error. The world didn't explode. I assure you.

[Miab419]

Maybe it already has and you wouldn't be able to perceive it... 0_o

It really depends on what high school you go to. Some schools will have better math programs than others, which may more likely go into stuff like this

[brainiac3397]

I shall spend my lifetime to prove that you CAN divide by zero. Sure, the proof will probably require a few volumes and perhaps a intelligence capability of infinite level...

yo dog i heard u like meth emaphemtme dog youdo you want to shoot meth in ur fucking harm hahhaha jesus

I had to know it in my Trig class, and if I recall correctly my Alg II class as well. It's a pretty simple rule to remember. Don't sweat it. Just remember that if you try to divide anything by 0 in your calculator then it shits a brick and tears a wormhole in to the fabric of space at a random location so be careful.

You cannot divide something into nothing.

[brainiac3397]

0 doesn't have to be nothing.

[тωιѕтє∂]

That's what zero is.

[Miab419]

You mean unless it's been rounded?

[brainiac3397]

10 isn't nothing. The 0 after the 1 converts it into a value of what we know as TEN(10).

So zero isn't necessarily nothing, because if it was nothing, it would have no meaning placed before or after another value as nothing would be non-existent(thus a blank).

That's how I see zero.

Quote:10 isn't nothing. The 0 after the 1 converts it into a value of what we know as TEN(10).

the 0 in 10 just means that there is nothing in the ones place. you don't even need zero to write numbers in roman numeral.

And this is where i got my reason for why you can't divide by zero.

Yet we don't use such systems like roman numerals because they're too large a hassle as the numbers grow larger. Surely nobody would like to do their mathematics with roman numerals.

The zero means there is nothing, thus zero isn't nothing because it has meaning. Nothing wouldn't have a meaning except for being nothing.

[тωιѕтє∂]

Zero places no value.

[brainiac3397]

But does no value make it nothing?

[тωιѕтє∂]

10 + 0 = 10, meaning 0 adds no value, adds nothing. It's nothing.

[Miab419]

It's the difference between 1 and 10, or 100, or 1000
