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.

don't take it personal bro. I believe this is just fun.
Haven said that, he will be just to do it that way if we use the absolute value.
-10 = -1*abs(-10)
so 10-10=10+(-10)=10+(-1)(abs(-10))
=10-(abs(-10)).
Now I guess we can square the two values
Note: be lenient enough to permit the square of an absolute number because its just a measure of distance from zero.
But like I said, its all fun. we all know anything divided by zero is undefined.

brytandre:

Sorry, it doesn't make sense

Sorry; sarcasm is not your forte.

As much as I would say the guy is A genius. Why must he represent 0 as 100 - 100. It could be 5 - 5 let him try another number that's not a perfect square to see if he'll arrive at 2. If he doesn't, then he's wrong

brytandre:
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

Does that help? It has to be a perfect square for his premise to hold, otherwise it is null

logica:
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?

lol
Dude, you just murdered the whole thing.
Anyways, I think he deserves some credit for giving the 0/0 thing a 'new' twist and getting some people here mathematically active. The proof may be a form of intellectual 'masturbation' for the poster, but it is a rather stimulating one. (I learnt something here today believe me)

Sorry. Looks like we ve had enough exchanges today. Sarcasm not intended please, just excited at the sight of this thread. Hope u understand

But this has got me seriously reasoning[/quote]

[quote author=brytandre post=33614483]

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

Man why are u complicating things, ok I don't have a degree in maths or applied maths. But I have degrees in common sense. Strong man don't sweat the small stuff

wonda26:


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

where do/did u school ? *Pls No insult intended*

We can also arrive at 1 with his ridiculous solving. But nothing is impossible..its science..but where's that bull and shit..ok bullshit

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!

mayopic vision is your problem (10+10)(10-10) / 10(10-10) = . Maybe we where taught different bodmas, buh mine says remove the brackets b4 dividing and if you do so, u'd get 0/0. Pls go back 2 your elementary mathematics and leave maths 4 sane people till u fully understand and tink like a learned person.

cupid1:
He started failing it from the point where he struck out 10 and -10,the 10 on top is supposed to equate to -1 when divided by -1 which when put into the equation, will give you 19/10.
And secondly, you cant stricke out numbers that way. They are in brackets in their own different equations i.e an equation in an equation.
So my point is, the person who provided this so called 'proof' is a dullard
May vice elementals from the seventh heavens strike the next person that quotes me with madness

sorry, but you seem like the real dullard here.

He struck out the whole (10 - 10) at the numerator nd the (10 - 10) at the denominator, not just 10 nd - 10...

It's a pity you got 122likes. Smh

BODMAS AGAIN?!


See it this way bro: (a+b)(a-b)/a(a-b)....(where a=b)

Do we need BODMAS before we identify a common term on both numerator and denominator to cancel out (a-b)?

Besides:

It is (a+b) x (a-b) / a(a-b) so u can cancel out


Now compare to (10+10)x(10-10) / 10(10-10) .....definitely holds that (10-10) can cancel itself out. Thanks

In mathematics, for an answer to be correct, it has to be logical and unique. The answer follows a logical procedure but it fails the condition for uniqueness of solution because you can get a different answers following that reasoning for different numbers and by other possible orubebe. The problem 0/0 sadly has no unique solution. Thats why its called undefined. I hope this helped you in some way to understand the mathematical jagbajanties that is causing yamyamalysis.

i get you my friend buh that bracket already gives 0 from what he did, is sayin (10-10)/(10-10) = 0/0 = 1 ........ Can u see wer the fault is nw. When u simplify the numerator and denominator by opening brackets, it is supposed to be equal to when you collect any terms and bracket them up. But in this case its not so.

0/0= error, no answer
10-10/10-10 is not one but no unique answer

(10+10/10) ×(10-10/10-10) = no unique slot

follow the rules but I admire your ingenuity

from: prof of mathematics

0/n= 0

n/0 = infinity
0/0= no unique answer can never be equal to 2

I understand u well.

From a BODMAS point of view, that bracket MUST be opened, and it ruins everything

But from an algebraic point of view, leave it as it is (since it has a like term) and cancel out.

That's wat he did. I argued with @logica that BODMAS is negligible in some maths, can u see wat I mean? Would it help in this case? Not at all

I knw say I no sabi maths....but dis is fucking wrong

Guys, there is a reason its called difference of two squares and not difference of same squares.
a^2 - b^2 = (a+b) (a-b)
a^2 - a^2 = (a+a) (a-a) = 0.
a at any given time cannot be equal to b or d rule is void.
The genius simply disobeyed the rules when he figured in that principle to his proof.

brytandre:

I think you are tired and need to take a rest; better yet go and sleep. This is the first time I am mentioning BODMAS on Nairaland; talk less of this thread.

I've been laughing at people's comments here. While some have given valid answers, others still see this little piece as a puzzle. The answer is UNDEFINED! 0/0 can be any number (real or complex), provided you guided by a set of constraints within a feasible solution space.

Or u didn't get the English

Difference is the -

Two squares: a^2 and b^2


Difference of two squares is a^2 - b^2


E.g what's the difference of 4 and 2. Soln: 4-2 = 2.


So there is no ruling disputing whether they could be equal or not. They are just squares. So a can be equal to b. Thanks

@all.

I wonder why some people who claimed to have studied mathematics said the steps are wrong. Common, they are right. The only wrong thing that made everything wrong is that...

He started out with ASSUMPTIONS

Therefore it is a MUST he proves that the CONVERSE is true.

Now, can the person who proved that go ahead to proof that 2 = 0/0?

Mind you, it is not by reversing the steps, it is about using the opposite of the assumption he had used earlier.

Real Analyst in the room should understand this better.
