while it is true that for the equation y*0=0 y= all numbers, for the equation y=0/0, y is undefined. there are certain rules for our math system, and one of them is that you can't simply change the original equation to get different answers. when you rearrange the equation in the way you did, you are basically throwing out the fact that a number was divided by zero in the first place. the truth of the matter is, if the equation is given to you as y=0/0, it is undefined and if it is given as y*0=0, it is all numbers. it is the way the equation is presented in the beginning that makes all the difference.
