Division by zero is undefined or infinity, right?
But we can multiply numbers with zero.
So, say... 2*0 = 0
This must mean that
2 = 0/0
2 = undefined or infinity?
How to work around this problem?
Why must it mean that 0/0 is 2?

Because,
(Take another example)
2*3 = 6
2 = 6/3
no, your logic is flawed... but to prove that, however, it will take many many pages of calculations

Thanks for pointing out that thread to me.
However, the answer I am trying to get from this thread is a work-around a problem which suggests that :
any real number = infinity, zero, 1, or not defined
If you look at the thread that bloodrider highlighted, you will see that your initial explanation is incorrect. 0/0 does not equal infinity, it is simply undefined.
This therefore means that you cannot equate 0/0 to 2 (even though all the rules of mathematics have been followed). Doing this, you are saying that 0/0 only equals 2, and nothing else. But 0/0 can equal 3, or 4, or 5 million and 2 (etc.). Therefore, the equation 0/0 = 2, must be written as 0/0 = undefined.
This hopefully explains your problem.

Okay, so does that mean :
0/0 = not defined
0 = not defined*0 ?
(Silly question, I know, since 'not defined' is not a value at all
)
In essence yes. What you basically have there is the rule when mutliplying by 0. Any number (an undefined number) multiplied by 0 equals 0.
Does that help.
So, basically,
Any natural number * 0 = 0,
but following basic rearranging, you can not write
natural number = 0/0
That makes sense...thanks. 
yaah I too agree this kind of topic already exist and I too posted my post in that, anyway for the present query I guess you are a bit confused with mathematic laws, how can you say 2=0/0 by saying that 2*0=0, I am simply not getting any idea...
You can't divide by zero but you can multiply by zero. =P Simple as that o_o
it's simply undefined because you can't have zero piles of something, but you can have five piles of nothing.
Wow, that was a hard problem. I bet I can not solve it all by myself. Anyhow, can you cut a round cake in 8 parts only with 3 cuts? Think about it.
