Ghrk... no. No, you can't.claymorez said:I can go with that - thou you could always be difficult and argue 0.A* (pretend * is above value A and stands for infinite sign).
0.A* x 10 = A.A*
ergo 10 = A.A* and 1 = 0.A* and therefore you could say 9 = Aso proportional expansion

If you are postulating that you could multiply any real number, raised to the infinite power, by another real number, you're insane. Every number raised the the infinite power is equal to infinity. You cannot multiply infinity by any real number and get any answer other than infinity.
Not to mention that any real number less than one, raised to the infinite power, will be equal to that real number's inverse raised to the negative infinite power, which means that the limit of the number's value is zero. Again, the concept is that you can't multiply zero by any real number and get anything other than zero.
To go back to your original question; in the real world, there is no such thing as zero. When you have zero of any quantifiable object, it means you have none of the object in question. When you are moving at a rate of zero in units of distance over time, it means you are not moving.
Conversely, Mathematics depends on having a quantifiable value relating to the absence of something. You cannot have equations with addition and subtraction without zero: It would be impossible to solve X + 1 = Y - 15 if we were not able to declare that X + 14 - Y = 0. If you had two mathematical statements, and the subtraction of one from the other was not zero, then you could not say that the two statements are equivalent.
It's when you introduce the concept of zero to other arithmetical functions such as multiplication, division, exponents, and so on that the concept of zero needs to change in order to work within these other functions. While we can state with relative certainty that 0*n = 0 and 0/n = 0, just like 0 + n = n, and n - 0 = n; things need to change when we try to do more complex things with zero.
You cannot divide by zero, no matter what. Even with attempting to divide zero by itself, you cannot divide by zero. You cannot divide any real number into enough pieces so that each piece represents the absence of the object. It doesn't work that way.
0/0 and infinity/infinity are indeterminate forms of a function. It is impossible to solve because you have no way of determining the ratio in terms of a real number multiple.
Think of it this way:
Say I have zero ducks, and I want to divide my ducks into groups so that I can give my friends zero ducks each. How many people can I give zero ducks to, out of my zero ducks to begin with?
Conceptually, I can give zero ducks to an infinite number of friends because there are no ducks to divide, and I am giving no ducks to everyone. BUT I cannot tell each of my friends how much of my zero ducks I am giving them, because there is no way to quantify which part of my zero ducks is their zero ducks.
So, zero both exists and does not exist; it is both a core concept of Mathematics, and it doesn't exist in the real world.
