a=/=0
If I have (a) of anything, number or otherwise.
I multiple (a) by (0)...
a*0 = 0
Why does (a) disappear?
The multiplicative identity property of zero?
Properties are changed all the time in mathematics....see "wheels" and "meadows"....
So why not this property....I have NEVER seen anything disappear. I might not know where it went. Or have seen it leave. But it did not disappear.
