0/0=0
0*0=0 0+0=0 00=0 zero or the magic number. the return of zero. with tom hanks, bruce willis, anthony hopkins, matt damon, lucy liu, rocco sifredi, clara morgane and nathalie portman.. yey! what is the probability that this film will exist one day? P=0 the return of zero!

hmm, if the reciprocal of 0 were defined, then you actually could get to this:
Code: +âˆž = + (1/0) = 1/ (+0) = 1 / (0) =  (1/0) = âˆž which doesn't make sense in many fields, but one interesting one might be the one used in SmithDiagramms One good reason why 0/0 is usually considered undefined is the following: Code: 0 * any_number = 0 <=> any_number = 0 / 0 _________________ MCD  the inevitable return of the Mad Computer Doggy __/ .+~ .

Hmm.. 1/+0 is not equal to 1/0; they are pretty much very far away (from 0) both.
Actually, would it make more sense if we said that the function r(x) has two returning values when x=0? (let's say oo and +oo)? (note i don't particularly support this idea). r(x) is undefined at 0 because you do not know which of these two values to take  but the ambiguity can be solved if we use the +0 and 0 notations (they simply mean "take the positive or negative, respectively").

On the projective line they are both the same point  and the line becomes a circle then.

0 cake, divide by a number ~ resulted => 0. no division could perform, because no cake. 0/number = 0 5 slices of cake divided by 0 (person) = 5 slices of cake no division could (perform), because cake consumed by nobody. number/0 = number (according to my logic) 0 slices of cake divided by 0 human to consume = ill logic why we want to divide empty with empty?

if 0 means ZERO
for me, it means, whatever thing/algo that you associated with 0, will not and should not have any effect on the resulted calculation.

3 * 2 * * * * * * 3 cols and 2 rows, so we got 6 dots. since i said, if 6 dots divide by 0, we have 6 dots still. so 6 * 0 = 6, 6 * 1 = 6 6 * 0 = 6 Code: ++  *     *   *   *   *   *  ++ 6 dots exists, but no row been assigned to it, they scattered around like above ascii picture. 6 * 1 = 6 Code: ++      * * * * * *          ++

forgot an essential detail.
0+0=0 then, 6*0 = 0 and in return, 6/0= oo why? simple, zero is nothing, how many nothing in somthing? an infinity. then 6/0=oo and not 6 or at least 6/0= +32767 in 16 and 2^311 in 32bits infinite depends on the resolution of the system, and is always the bigger value you can have. in signed 16bitys, the maximum is 2^151, there are no value above this one.

∞*0 =0 because zero have the priority.
it's more frequent to cross zero than infinite. and zero is sinonym of nothing, then, nothing*infinite = nothing. zero can be interpreted as NO. and NO is the total negation of something. then, NO * infinite = 0

so i think i could introduce a new concept.
numbers exists in 2 form, scattered (S) and unscattered (US) form. maybe we need to draft some rules for them when S vs S, S vs US, US vs US

for me, i think infinity is a concept, it is not a number. u can't perform a number * infinity, because, infinity is a CONCEPT.

sleepsleep, I think you are right.
try for example to picture in your mind an infinite universe, the mind can not comprehend something infinite, paradoxically you can not picture a finite universe, because you will think "what's beyond that"

Isn't a gift to always be thinking about what is beyond?

it's both a gift, and a torture.
gift cause we have the power to think we are moer than skin, muscles and bones. a torture cause we see we are only skin, muscles and bones. you have the choise. don't know, and be happy, but a bit stupid. try to know, then, don't see any magic in the world, all have a logic explanation, then, no fantastic, just facts. i'm in the second case, but more in the middle, try to know the maximum, don't know anything, be sad of my human condition, but feel happy to know there are billions light years to explore, and we cannot. no space ships to see the limit of our universe, and see that there is something different beyond the limits. something so different that it cannot be part of our universe. our universe is composed of vaccum, atoms, planets, suns, galaxies, galaxies clouds, etc... waht can be the others things? that are not in our universe? is it possible that imagination, in our brains, creats universe somewhere, in other dimensions.

I noted just another thing: while infinity is not an element of the real numbers, there are several uses of the set of the real numberes unified with positive and negative infinity, denoted as Code: ;tex \R \cup \{\infty, +\infty \}

I think this thread turned interesting to be kept in the unsafe Test Area, I'm moving it to Heap.

I give a small prize to the first person that can explain a simple method to convert 0.012345679(012345679) {parentheses meaning the nine digits are recurring} into 1/81, and can also generalise the method for any number, in any base, with any arbitrary recurring sequence after the decimal/binary/hex/whateverbase point.
The prize will be one star so don't be disappointed, okay
