0 is a real number

>>10553796

>>10553798
You can have, for example, 1 of something but you can't HAVE 0 of it. It's just a concept, a label, for nothing, like infinity. It's not real.

>>10553796
Correct. Zero is the representation of infinite neutrality.

>>10553806

The Real Numbers are well definied and zero is a part of it.

If you by "real number" mean something else than the field of Real Numbers then you must say so.

0 is a real number, 0 is not a natural number

>>10553862
>>10553859
Explain how zero is a number.

>>10553889
First, define what a number is

>>10553928
A quantity.

>>10553944
Then 0 is a number that represents nil quantity. If I have 1 apple and give one away I have no apples, or you can say I have 0 apples.

>>10553796
0 is the dedekind cut that separates all positive rationals from all negative ones. Thus by definition it is a real number.

Every number is just made up
If you mean that it doesn't make sense to talk about how you can have zero of something, then how do you describe how many brain cells you have?

the word “real” in the term “real number” does not mean mean to mathematicians what it means colloquially. it is just a label for one of several different kinds of numbers. there are also e.g. “imaginary numbers” and that doesn’t mean they are fake or useless in physics and engineering

>>10553976
>Then 0 is a number that represents nil quantity.
Impossible.
>If I have 1 apple and give one away I have no apples
In that context you have -1 apples.
>or you can say I have 0 apples.
You can't have something that doesn't exist.

>>10554031
>0 isn't real because you can't have 0 of something
>you can't have 0 of something because 0 isn't real
Well, I'm convinced.

>>10554031
retarded argument. reminder: 1-1=0. good luck at the grocery store

just wait till this nigga learns about practical applications of imaginary numbers

>>10554031

but -1 exists? lmao

>>10554031
>If I have 1 apple and give one away I have no apples
>In that context you have -1 apples.
hory shet lmao

>>10553976
Wrong, 0 represents the lack of a quantity

>>10554044
>>0 isn't real because you can't have 0 of something
Wrong. 0 isn't a number because you can't have that which does not exist.

It is logically impossible for "nothing" to exist, due to the very fact that "something" exists. You cannot have that which does not exist.

>>10554062
wrong. 0 is a quantity. open a bank account and then take all the money out, it will contain 0 dollars. bankers aren’t doing it wrong

>>10554046
>reminder: 1-1=0
1 - 1 is not a valid calculation.

>>10554055
1 and -1 are the same thing in different contexts.

>>10554068
yes it is. sauce: 1st grade math

>>10554057
And explain why you're laughing.

>>10554066
No, there will be no dollars in the bank account. It's a binary check, there are either dollars or no dollars. The 0 is just a placeholder to say that there are no dollars.

>>10553796
OP just answer this question, how much sex have you had in your life ?

>>10554066
>it will contain 0 dollars
It's containing -however many dolllars there are

why is /sci/ so easy to bait

>>10554064
Women you have had sex with do not exist. You've had sex with 0 women.

>>10554078
then show me the calculation of how much compound interest i would make on “no” dollars. something that a computer could do without verbal arguments. this is an important calculation for a computer to be able to do in practical banking

>>10554072
>sauce: 1st grade math
As if that's supposed to be evidence of its validity...

1 - 1 doesn't equal anything.

>>10554074
>1-1=-1

>>10554085
0=-anything you want is not a valid calculation. otherwise i can go and bankrupt the economy by going to an ATM and withdrawing all my money and declaring it’s -1,000,000,000,000 dollars

>>10554093
1st grade math denier. wow. let’s go back to here: >>10554066
explain how bankers are doing it wrong please

>>10554090
By women, whom do you refer to?

>>10554094
So you believe +1 and -1 are separate numbers?

OP is either severely retarded, or an ingenious troll.

>>10554106
Exactly.

>>10554097
>and declaring it’s -1,000,000,000,000 dollars
But it is.

>>10554113
okay, go crash the global economy then. i’ll wait to see you on the news

>>10554102
>explain how bankers are doing it wrong please
Why would they do it right? It's rigged.

Is zero negative or positive like all other numbers?

>>10554112
Are you referring to a quantity of women?

>>10554120
answer the question please.

>>10554031
>1-1=-1

>>10554064
>repeating exactly the same circular argument
Anon, are you okay? It normally takes a few more posts before you run out of bait.

>>10554119
If you claim to have x amount of dollars, then you are also claiming you have -x amount of dollars.

>>10554131
no, debt is not the same as savings. good luck buying a car

>>10554123
A quantity of women that do not exist is still a quantity. The empty set is still a set. You ate confusing the size of the set with the members of the set.

>>10554126
Can I give you zero dollars?

>>10554139
you just did.

>>10554128
According to you it could take 0 posts.

>>10554136
>debt is not the same as savings
Your savings are everyone else's debt.

>>10554144
so my gold bars are made up for by everyone else’s antimatter bars of anti-gold?

>>10553796
0 is irrational since 0 =! a/ b , with a =! 0

>>10554149
0 is allowed to be in the numerator of rational numbers, thus since 0=0/69, 0 is rational

>>10554137
>A quantity of women that do not exist is still a quantity.
Read that again. Do you not see the contradiction here?
>The empty set is still a set.
"Empty set" cannot exist.
>You ate confusing the size of the set with the members of the set.
What's the size of the empty set?

>>10554141
How?

>>10554155
AOC’s horny pornstar twin is 1 woman who does not exist. refute this

>>10554155
Arguing that the empty set doesn't exist is like arguing that a box ceases to exist when it's empty.

>>10554157
how many shits did i just give about you?

this whole thread is fucking retarded

the real question here is “why do zero deniers exist still?” i know that back in ancient/medieval history there was some sort of controversy about the concept of 0, but why do people do this today? is there any contemporary identifiable group or school of thought who deny 0? i’d like to know who or what is responsible for these brainlets. must be some newage hippy shit right?

>>10554155
>Read that again. Do you not see the contradiction here?
Read it again, do you not see that it's the women that don't exist, not the quantity?

>"Empty set" cannot exist.
The empty set is just an empty container, of course it exists.

>What's the size of the empty set?
0

>>10554191
>why do zero deniers exist still
They don't exist. You are being trolled epic style. Stop bumping.

>>10554191
>why do zero deniers exist still
They don't exist. You are being trolled epic style. Stop bumping this.

>>10553796
>In mathematics, a real number is a value of a continuous quantity that can represent a distance along a line
>Someone could measure zero distance along a line (i.e. not moving from a starting point)
>Therefore zero is a real number by definition

>>10553806
Numbers are just labels, they aren't real.
Beat that

>>10554128
Well, it took 2. Not far off.

You can't have 0 of something but you can have 1 of something.

You can show me 1 apple, but if you try to show me 0 apples you can't. You could point to an empty space but that's nothing, I could just ask how would I know that's 0 apples and not 0 pies or 0 unicorns?

Brainlets came up with 0 because they can't understand the difference between concept and reality.

>>10555566
again, can a bank account have zero dollars in it? i hope you do better than the other anon who says if you take all your money out of your bank account it actually has negative one trillion dollars

>>10555592
it has nothing in it. not 'zero dollars', it has nothing. 'zero dollars' is just a label you give when you have NO MONEY to help you distinguish the thing that you no longer have.

>>10555906
how is an account with "zero dollars" in it not absolutely equivalent to "no dollars"?

if i have no dollars in any of my pockets, then i have zero dollars on my person. no? do i have negative a trillion dollars instead or something?

>>10555906
>>10555912
will you fags shut up, this argument is fucking retarded

0 has no imaginary component, therefore it is a real number

>>10555973
no, the argument that bakers use the concept of 0 very successfully in practice debunks the “0 isn’t real” retardation

>>10555977
*bankers not bakers
but probably bakers too, come to think of it

>>10555980
I'm not disagreeing with you there, but let me just remind you of what's happened in this thread: someone made a bait post saying that 0 is an imaginary number, and then you 2 fuckwits went off ranting about cereal boxes and bank accounts

>>10555996
concrete examples are what is needed in the case of philosotards trying to debunk common sense

>>10553806
I HAVE 0 reasons to live

>>10553806
Nothing is just as real as something.
There's none of something everywhere that something isn't.

>>10554078
You just defined a real number which we call 0. Next time you think in your little retard brain “0 isn’t real”

Just read this definition YOU fucking wrote and use it as 0

>>10554090
No -3.5b women

>>10557842
-3.5b women = 3.5b men

>>10557839
In this case it's just a placeholder. We need a numerical representation to stand in for the binary check. 0 is not real since any operation with it past addition or subtraction is not well defined.

>>10557897
can you please explain why you hold these silly anti-math views? is this some sort of philosophy or newage shit or some weird religion?

>>10557897
everything is a placeholder, you fucking idiot

>>10553806
Name something you can just have one of. "Things" are just concepts and categories we've invented and evolved to understand the world. They don't exist as discrete entities.
