\(\frac{100-100}{100-100}\) =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. حكيم الفيلسوف الضائع · 3 years ago

why not 100-100/100-100=0/0 Anisha Mohapatra · 1 year, 2 months ago

While cancelling, you are assuming that \(\dfrac{0}{0} = 1\) which is not the case Akhil Bansal · 1 year, 7 months ago

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. Alex Li · 1 year, 8 months ago

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 Nirmalya Basu · 1 year, 8 months ago

@Nirmalya Basu Oh yes you are correct my dear :p Anik Mandal · 1 year, 8 months ago

no.....you cannot divide the numerator and denomenator with zero Satwik Kumar · 1 year, 9 months ago

Is \(\lim _{ x->a }{ f(x) } =\frac { 0 }{ 0 } \) defined? If yes, why so? Manish Dash · 1 year, 11 months ago

10-10=0 in maths /0 is error Hilmi Haniffa · 2 years, 1 month ago

10-10 and 10-10 cannot be cancelled cause 0 and 0 cannot be cancelled Ajay Chandra · 2 years, 1 month ago

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 Rohit Singh · 2 years, 11 months ago

Could anyone give me an exact reason as to why division by 0 is undefined........ Anik Mandal · 3 years ago

Log in to reply

@Anik Mandal 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 Kushagra Sahni · 3 years ago

@Anik Mandal 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 ago

@Anik Mandal 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 Baidehi Chattopadhyay · 3 years ago

NO YOU CANCELLED (10-10) WHICH IS 0 AND DIVISION BY 0 IS NOT DEFINED Kushagra Sahni · 3 years ago

@Kushagra Sahni Hey its wrong i too know it...practically its not possible but theoretically its possible. Shrey Fadia · 3 years ago

@Shrey Fadia How can it be theoretically possible, Shrey????? Anik Mandal · 3 years 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 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 ago

@Shrey Fadia Even theoretically it's impossible since it uses division by zero, which as we all know is undefined. حكيم الفيلسوف الضائع · 3 years ago
