What would announce the appocalypse for you?

x=7x/(1-1)
x=7x/0

OOPS

Ummm, then X is 0 by your first equation. x(1-1)=7x=x(0)=7x=x=0. :/

So technically...

0=(0/0)
How hard was that?

We just went over this today in my math class.
Pretend a does not equal 0. Using this, a/0=c says that a=cx0. We just said that a does not equal 0, so this is utterly false.
Pretend a does equal 0. Using this, 0(formally a)/0=c, which means that 0=cx0. This gives an answer that c=any possible number. This is not good.
Using both examples, 0/0 can't be defined.

If c is of the set that equals any real number, why is that bad?

That just means that either 0/0 is undef. or it equals anything. Actually, I believe it equates to the set of real numbers.

Really?? Mods/Super Mods/WPM can ban each other?!?!

It's bad because variables in an equation are assumed to have a unique answer. Yes, sometimes there are two answers, due to square roots or something, but to have an infidente number of answers is pointless.

Having it equal to anything is what makes it undefined. The problem with your second statement, is that, in my second equation, c can equal anything. It can equal, 1, 2, 3, -1, -2, -3, 0, pi, square root of 7, square root of -7, ect. You can literally shove ANY combination of numbers, symbols, and the like into that c, including things that are undefined, which leads to an obvious messy mess, and an equation that is just silly and useless.

And think about it this way. Numbers are constant and theres always patterns. What kind of constant can there possibly be when 0/0=every number, but 1/0, 2/0=impossible? This gives no reasonable way to use a/0 and find anything of substance. Because of this lack of substance, it's classified as undefined and is probably the single most useless equation anybody can think up. lol.

WAIT NO!

Simple way of putting it

Not so fast, Papi. People once thought that the equation x^2=-1 was the most pointless equation, and now it's used majorly in specific areas of higher mathematics.

Of course you can shove any number in as the solution. That's the whole point of 0/0. Think of it this way: division is the inverse of multiplication. So if you needed the answer to "Zero divided by zero is what?", you subconsciously think "Well, zero times what equals zero?" The answer happens to be anything. Is this point useless? So far, as most mathematicians debate on whether 0/0 is really defined, but I think that it will eventually have some applications.

:/ people have tried to divide by 0 since they recognized 0 as a number, and have tried to explain it.

Division is more then just the inverse of multiplication (which is more then just adding multiple times). Yes, that point is useless because it gives the equation 0/0=1, 2, 3, 4, etc. It also doesn't give x/0 any logical answer. I doubt it.

 

[Zyflair]

0 is unique in its own way. It is neither positive nor negative, and thus different. I really don't see the point of x/0, but I can say that, one day, some random person actually finds a use for 0/0.

Division is more than the inverse for multiplication? Amuse me.

 

[StarlightSearcher]

You can't divide something by 0. But can't you divide 0 by a number instead?

I highly doubt it. Theres nothing "new" to discover about math. There may be new shortcuts to use or applications, but its highly unlikely that something may devolop that can can use division by 0.

Division can be thought of as repeated subtraction, using the partian model, or as a missing factor of a multiplication problem.

 

[StarlightSearcher]

I know something else. The apocalypse is when when can get an even number from prime numbers (without dividing by 1 or the same number)

Sure you can. It's just you'll have fractions, which, let's face it, not even thier mothers love.

 

[StarlightSearcher]

Another one is when people can get every number in Pi (which is infinity)

 

[Zyflair]

We have sent pi to billions of digits. We'll probably find a pattern to pi and be able to predict the rest if its digits about 30 years into the future, when our super computers have improved dramatically.

 

[StarlightSearcher]

Another thing is when people become smarter than supercomputers...

I cannot imagine that.

Doubtful. I once heard that it would take the entire universe to fill up all the digits of pi when written on a chalk board, and I wouldn't doubt it. Of course, I'm not going to sit here and try to calculate pi to find a pattern, but I seriously doubt we'll notice one ever. There may be a pattern repeating eventually, but thats just due to the shear numbers in pi.

division by 0

a=b
a^2=ab
a^2-b^2=ab-b^2
(a+b)(a-b)=b(a-b)
simplify
a+b=b

there ya go, division by 0
