    Mike Steere Can't factor out zero

    Maciej Sidorczuk There is mistake at line 5. You cannot divide numerator and denominator by 0!

    Mustafa M. Al Khabbaz the mistake you did is that you crossed out two zeros; one is is numerator, and the other is the denominator which is wrong. (10-10)/(10-10) is not more the the original case (0/0).
    Your proof if not more the following:
    (0/0)*2=2 <Wrong Answer>
    0/0 is a special case

    Omar Salim Your expression of 10(10-10) is wrong, it should be 10.10(10-10)

    David Echeverria the numerator and denominator were not divided by 0. that expression is equal to 1, so (10-10)/(10-10)=1... like 1/1=1, 2/2=1, etc.. but that is wrong because the sustraction should be done first, because there are between parentheses...
    if the right expression were 10.10(10-10) the result is 10.10(0) and that is equal 0 too..

분자 분모를 0으로 나눌 수 없다.
그런 식이면..   0/0=(100*0)/(1*0) = 100 이렇게도 할 수 있다.

자. 여기서.. 실제로 0/0은 얼마일까?
