Hello.

As many of us know, computers have trouble with division by zero. However I have discovered a way.

We simply add one to what we are dividing, add one to the divisor, and subtract one from this:

((+1/+1)-1)

The answers show division is without difference from adding, subtracting, or multiplication. When using zero in mathematics, there is nothing to operate with so the answer remains as it was.

For example:

(((1+1)/(0+1))-1)=1
(((2+1)/(0+1))-1)=2
...etc.

The interesting work comes from dividing zero...

Not true for the IEEE754 standard implemented in most modern day computers. It just results in +INF or -INF (positive infinity or negative infinity), and this is perfectly well defined in the standard. No trouble whatsoever.

So you're not dividing by zero (an ill-defined operation), but subtracting to zero (a well-defined operation). This has nothing to do with dividing by zero anymore.

I'm unclear as to what you mean exactly, but dividing is a separate operation from adding or subtracting; they are not (directly) related. In other words, they are very different. It is the inverse of multiplication, and thus different from that as well, although it's very related to it.

Might I suggest you look up what "vector spaces" are? The best way of understanding how these operations are defined is by looking into how they are defined for vector spaces.

You seem to be confusing the mathematical concept of zero with the concept of void or nothingness. They are not directly related, and should not be equivocated.

Again, you are not dividing by zero anymore.

And, reversing that "equation", this would mean that
1 x 1 = 0
2 x 2 = 0
etc.
Fail.
Sheer crap.
(If I recall correctly - and I know I do - you have tried exactly this elsewhere: and been shown that (and how) you are wrong).

(I just noticed: Counter, why is the topic title "The power of the human"?)

Also, the procedure gives the wrong answer for "sensible" divisions

For example, consider 6/3 = 2

Using Counter's method we have
$\frac{6}{3}=\frac{6+1}{3+1}-1=\frac{3}{4}$
which is clearly wrong.

You are dividing six by three, not six by zero.

Yes, and you:

are dividing by one, not zero.

7 of the last 8 cesspools have been from counter. Is that some sort of record?

Could be, could be...☺

I'm dividing by zero. That happens to be the process dividing by zero. ☺

Looks like James forgot to lock this when he moved it... Let's fix that, shall we?

I thought people couldn't post to the cesspool. Maybe I ought to look into that...

It isn't possible to create a new topic here - however, if a thread is moved without being locked, it can be replied to.

Ok. Food for thought.
