Dividing by zero
#24
RE: Dividing by zero
(September 30, 2013 at 8:12 am)Rational AKD Wrote: rather than using limits, you can use simple algebra to show why you can't divide by zero.
first, take expression like 1/0 and make it into an equation.
1/0=x
this equation would be equivalent to 1=0x
0x equals zero according to the multiplicative property of zero
so you get 1=0 which is simply not the case.

but what about 0/0?
this would be equivalent to 0=0x
which then gets you 0=0
so in the equation it works, so can it be done? well, not really. the problem is we have to solve for x, so then we have to answer what is x? well, x can literally be anything because anything times zero equals zero. so you pretty much get 0/0= all real numbers, which simply can't be the case for a division operation which is why it is instead expressed as undefined.

That's what I just said about 2 posts ago.
