this guy just spice tinz up


nice try.

You are turning mathematics on its head. 0/0 is undefined because anything divided by 0 is infinity. Reason being that 0/0 can be equal to anything. For example, 0/0=500/2 which is 250 or 0/0= 64-64/4-4=4. No reason going to all those manipulations.

Well, I give lots of compliment to the op for such a simple but thought provoking analysis.

If you are a mathematician or lover of mathematics, you will know that no valid mathematical proof will make 0/0 to be =2 even without look at any claim of proof. Intact the probability of that happening is zero.
I have to admit though that I went through the op proof a couple of time before I detected the mathematical error.

The numerator evaluation from line 3 to line 4 is the culprit.
-10 x 10 numerator line 3 is not equal to -10^2 numerator line 4.

Intact you can't raise any number to any power to give a negative number.

So, (-10x10)=-100
while (-10^2)=(-10x-10) = +100 ...which are not the same.

Every other mathematical argument in the op proof are correct.


But the incorrect step above invalidates the proof.

its wrong... anything divided by zero is undefined...0/0 is undefined.

RedArrow:
Do you have idea of complex mathematics? Pls do, it will help you to understand that whenever 0 appears @the denominator, the expression is undefined.

I do have an idea cos I'm a graduate of Mathematical sciences. UNDEFINED in terms of zero being denominator signifies that the answer gotten will be betw -infinity to +infinity. The answer could be any number depending on what the person chooses it to be.

In this case, if you say 0/0= 1, u are correct (provided u can prove it) just as he said 0/0= 2. But there will be certain constraint. As for his, you can only use perfect squares. Any other number will not get u 2.

MrOlai:


Your a clown! You know nothing about Mathematics. In fact, you need to be flogged for mentioning BODMAS here. What has BODMAS got to do with this?

Please, stop disgracing yourself!

i wudn't want 2 go into any serious arguement, i'v met some knw-it-all who claim they knw maths. Now, he said he did solve it ''mathematically''. Now if u are not an illiterate how can you solve maths witout the fundamental of maths 'BODMAS'. Bros if you are a student you'd knw that maths answers never change. What can prove him correct is if (10-10)/(10-10) = 1.......... Mr knw-it-all prove it. This will simply mean firstly that 0/0=1......... Bro you are no mathematician you are a dull thinker.

Jesus, I hate maths

logica:
OK sorry. 0/0 is a known paradox (contradiction) that is over at least 2000 years old.

Okay.
Thanks.

(100)-(100) is this correct 2 place this way If it is then.........(10^2)-(10^2) check it very well bro.

wonda26:

10^2 - 10^2 = (10 + 10)(10-10) is very correct.

In mathematics, it is called 'Difference of two squares'


If you doubt, try simplifying the right hand side of the equation

Not possible. You have to use math rule of BODMAS. And when you do that.
Then; (10+10)(10-10) never equals 10^2-10^2.

To show that 0/0 = 2

Proof: let {X:X perfect squares from 0 to infinity}, {Y:Y perfect squares from 0 to infinity}

Proved: Then 0/0 = (X+Y) (X-Y) / X (X-Y) = 2 for all X=Y or UNDEFINED (I.e other values) for X not equal to Y

Its tricky, but I stand by my position.

putting in parenthesis has not cancelled out the (-) sign.

Now this will make sense if you try to work back.
Q. Evaluate -(10^2)

A. -(10^2)= -10^2 =-10x-10 =100 ...You have to open the bracket first, that is the rule of mathematics.

My guy, that's simple quadratic equation na.

(10+10)(10-10)= 10(10+10)-10(10+10)

= 10^2+10^2-10^2-10^2

At this point he took out the two middle terms only (I.e 10^2-10^2) by subtracting them

= 10^2 - 10^2

So it is correct!

0/0 is undefined

If you did quadratic equatiom in school, u will know he doesn't need to do any -10^2 .

a^2 - b^2 = (a+b)(a-b) for all a=b or a not equal to be

So 10^2 - 10^2 = (10+10)(10-10) . Very very correct!

brytandre:

(10+10)(10-10)= 10(10+10)-10(10+10)

= 10^2+10^2-10^2-10^2

At this point he took out the two middle terms only (I.e 10^2-10^2) by subtracting them

= 10^2 - 10^2

.

So it is correct!

And 10^2 - 10^2 equals 0

I weep for you. Plz expand the expression you just wrote.

fio:

And 10^2 - 10^2 equals 0

That's where he is coming from remember? It's a mathematical proof ok. He is saying 0=10^2-10^2 = (10+10)(10-10)
That's the idea

Great to know that. I also have MSc in Applied Mathematics, the rule applied to the numerator is kool {diff of 2 squares). But the fact that the person is working on the REAL PLANE makes the whole prove absurd. The REAL PLANE does not accept zero as denominator. The graph will form an asymptote. For example, take a limit of a fraction as the denominator tends to zero, you will either have -ve infinity or +ve infinity which confirms what you said that the answer will be btw infinity to +infinity meaning undefined.

The proved utter rubbish. 101% wrong! 10^2-10^2 is 0 till tomorrow not 20.

Thanks a lot bro. I understand u well....it's gonna be graphically difficult to represent, hence the frustration of the early Mathematician to simply say UNDEFINED. To be sincere, I'm seeing something like this for the first time and I'm really happy to know someone is willing to THINK!

Note; 0.0000000000000092 can also be termed 0....... this can be represented graphically can't it?

u are wrong my frnd BODMAS says solve d bracket first. That shud give -(10^2) = -(100) = -100

THE PROOF is limited but correct!
0/0 can be equal to anything, that's why mathematicians say that it is 'undefined'. 'undefined', could be taken to mean any number within the range (-infinity to +infinity)

wonda26:

He applied the rule: 'Difference of two squares'

(a^2 - b^2) = (a + b) (a - b)

and did you see that what he expanded (10^2-10^2) are constants, they are not variable.
so, he's totally wrong.

Graph of 0.0000000000000092 does exist. After all it's a real number (as in, the number 0.0000000000000092 can be found on the real line)

It isn't even a proof really (in the strictest of terms).

If you are going to do this:

(10 - 10) / (10 - 10) = 1 (the premise on which his "proof" stood)

then there was no need for the whole rigmarole. You might as well do this:

0 / 0 = 1

Even at this point:

(10 + 10) * (10 - 10)
------------------------
10 * (10 - 10)

where he cancelled out the (10 - 10), why not do this:

0    (10 + 10)      0
- = ----------   *  -
0        10         0

Obviously now, the equation is not even making any sense. But let us further make more nonsense out of nonsense:

If you cancelled out the 0/0 on both sides:

1 = (10 +10) / 10 or 1 = 2

That makes a lot of sense doesn't it?

jstriker442:
my FRIEND this is very mathematically wrong buh i can say its logically correct. Maths tells us to use BODMAS in all we do under maths. Do u knw y i love maths ?? Becos it never lies. Follow the rules and any question must give thesame answer. Pls use BODMAS

Your are talking trash! In your statement, you wrote. " Maths tells us to use BODMAS..." I wrote "What has BODMAS got to do with this?" What I mean here is, what has the guy not done as far as BODMAS is concerned? He has done the right thing and yet you kept shouting BODMAS.

You later wrote " What can prove him correct is if (10-10)/(10-10) = 1". Why didn't you mention this before you started shouting BODMAS, BODMAS... when there is no error of BODMAS in the proof? That shows how mentally retarded you are!

Besides, who told you you cannot introduce or remove (10-10)/(10-10) in Mathematical provings? This is why 0/0 is considered undefined in Mathematics. It could be proved to give several numbers.

You now went back to meet your lecturers like I advised before you can make any sane contribution! It's really pathetic! When next any issue is raised on Mathematics, you better go and meet your lecturers first before shouting BODMAS, BODMAS, bla, bla, bla!

Then his premise could stand

0/0 = 0.00000000001/0.00000000001 = 2

Don't u think?

This could be applied to science and tech if looked into critically. Okay lemme stop before I take it too far. Lol

If he presented it the way u just did, maybe I'll form ignorance and be screaming "BODMAS" too. Sorry, it doesn't make sense

But people dull sha....... Nigeria is gone

adewaletb3:
So_fucking wrong. Why would you prove like a goat

ABSOLUTELY WRONG

Good thinking but the basic rule of BODMAS is not obeyed, 100-100 needs no reverse as subtraction is the last operation to be carried out according to the rule aforementioned.
