Kokaine:

But at the point you circled, you are not mearnt to know that 10-10 is zero. It could have been (x-y) at that point. The point is that the factors as a whole (in a bracket) are divisible and exactly cancle out.


The method is interestingly correct.

I'm sorry kokaine but in maths it becomes a constant/known factor once you input actual figures.

x-y/x-y could be anything. But when X = 10 and y = 10, both variables have accepted a fixed value. Hence 10-10/10-10 is a constant and not a variable.

The result is 0/0.

That's simply mathematics.

Cheers.

Sorry this section here in the pic below is mathematically incorrect.

You have divided zero by zero (0/0) and
and that cannot happen in mathematics.

Doing that leads to a situation called 'undefined' in mathematics. Meaning that you would get an unknown result and hence you are not allowed to do it within the ambience of mathematical laws of the universe.


That has nullified the quest for your solution. The result is mathematically unacceptable.

Cheers.


if you say, let (10 - 10)² = a, and proceed with the division it becomes acceptable.

coolJust about anything canbe concocted with figures. The fallacy is in the DIFFERENCE OF SQUARES. The operation for the denominator is unknown to algebra. Simply put, wot u do to the numerator, do also to d denominator. Afterall they are mirror images. I.e (10+10)(10-10)/(10-10)(10+10)=0/0=0

Re: Where Did This Mathematics Go Wrong? by Unleemeeted(m): 8:55am On Sep 24, 2021
I feel the problem started from that factorisation part below the division.. when u factorised, u did not check both side properly and something is still common to both side...

U wrote 10(10-10) instead of 100(1-1)...

I don't know maybe u get the angle I am coming from shockedshocked...

That Place you wrote (10+10)(10-10)/10(10-10)
It should be equals to Zero
Re: Where Did This Mathematics Go Wrong? by Nobody: 8:56am On Sep 24, 2021
Simran94:

No, it's correct actually. During factorization process, we don't see it as 0/0, (10-10)/(10-10) cancels out because they are the same equation, that's how factorization works. So the equation is correct

Unfortunately you are working with constants here and not variables in factorisation.

x-y/x-y will cancel out as long as X is not equal to Y

Everything op did is VERY correct.
However, no one can determine 0/0 exactly

It can be any other number than 2. Infact 0/0 can be any value!

He used 100, you may use another perfect square.

0/0 can't be determined PERIOD!

0/0 could be any number.

Let's do a reverse calculation.

0/0 = 2

0 = 2 x 0

0 = 0

you can only prove this if there is an unknown variables, but with the zeros meant the variables are undefined.. So no solution. But u free to assume Ur variables sha, but need to rep and notify, thanks

that is true pow(10,2) - pow(10,2) is zero 0. Lol. I agree ☝️ with you on this.
Re: Where Did This Mathematics Go Wrong? by Gabrinas(m): 9:02am On Sep 24, 2021
The calculations went wrong from here:

= (10^2 - 10^2) / (10^2 - 10^2)

= [(10-10)(10+10) ] / [10(10-10)]

The denominator 10(10-10) is right applying mere knowledge, BUT Mathematically, it is wrong.

Mathematically, factorizing 10^2 - 10^2 will never give 10(10-10) because 10 is not the only factor common rather 10*10 is the factor common leaving nothing than 0 in both term to remain which eventually gives: 100(0-0) = 0

(10+10)(10 –10) = 10 (10 - 10) + 10 (10 - 10)
. = 100 - 100 + 100 - 100
. = 100 - 100

How will you cancel (10-10) from 10(10-10) 10 is a factor of (10-10) and they are not independent variable. Hence you can't eliminate (10-10) and leave out 10

The difference of two squares formula states a^2-b^2=(a+b)(a-b) where a does not equal b. so it went wrong at 10^2-10^2

This is the only person that prove the solution to be wrong. Every other suggestion are still near miss
