\(\frac{100-100}{100-100}\) =2

Suppose a problem be given that \(\frac{100-100}{100-100}\) =?

Couldn't we solve it in this manner?

\(\frac{100-100}{100-100}\)

= \(\frac{10^2-10^2}{10(10-10)}\)

= \(\frac{(10+10)(10-10)}{10(10-10)}\)

Cancelling 10-10 from the numerator and the denominator we get,

\(\frac{10+10}{10}\)

= \(\frac{20}{10}\)

=2

You divided by 0 by canceling 10-10, but division by zero is undefined.

why not 100-100/100-100=0/0

Anisha Mohapatra - 2 years, 1 month ago

While cancelling, you are assuming that \(\dfrac{0}{0} = 1\) which is not the case

Well, 100-100=0, so from the very start you're kinda messing yourself over :P

To the point where no step doesn't divide by zero until (10+10)/10

It took me a while to notice though.

no can't do so my dear , because 0 (= 10-10) can't be cancelled from the numerator & denominator , and if we do so then we will get the answer which we ourselves can't explain

Oh yes you are correct my dear :p

no.....you cannot divide the numerator and denomenator with zero

Is \(\lim _{ x->a }{ f(x) } =\frac { 0 }{ 0 } \) defined? If yes, why so?

10-10=0 in maths /0 is error

Hilmi Haniffa - 3 years ago

Log in to reply

10-10 and 10-10 cannot be cancelled cause 0 and 0 cannot be cancelled

Dear friends why u getting problem in this is because u underestimated or forgot one thing that is

10^2=100. And -10^2 is also 100 so u must take. Both under consideration

Dividing zero by zero is not defined...Π™

Could anyone give me an exact reason as to why division by 0 is undefined........

Anik Mandal - 3 years, 11 months ago

Log in to reply

Dividing by 0 is not defined because if you divide 0/0 you can get any value from negative infinity to positive infinity because any number into 0 is 0. and if the numerator is non-zero then no number can satisfy the satisfy the equation

try to divide a cake made of air. it is like you cannot divide that does not a value or just "nothing".. :)

Edjoy Rodelas - 3 years, 11 months ago

If you divide by zero then all numbers become equal and this is thus meaningless, so division by zero is defined to be undefined!! If division by zero was defined then almost entire mathematics would crumble down

NO YOU CANCELLED (10-10) WHICH IS 0 AND DIVISION BY 0 IS NOT DEFINED

Hey its wrong i too know it...practically its not possible but theoretically its possible.

@Shrey Fadia How can it be theoretically possible, Shrey?????

Anik Mandal - 3 years, 11 months ago

Log in to reply

@Shrey Fadia NO NOT EVEN THEOROTICALLY. THE STEPS HE PERFORMED ARE ABSOLUTELY WRONG. HE DIVIDE BY 0

Kushagra Sahni - 3 years, 11 months ago

Log in to reply

@Shrey Fadia Theoretically possible? IT's using division by zero. the main step is not possible even! how can it be theoretically possible,,lol

Baidehi Chattopadhyay - 3 years, 11 months ago

Log in to reply

@Shrey Fadia Even theoretically it's impossible since it uses division by zero, which as we all know is undefined.
