I am (obviously) not a math person but still have been trying to understand how 0 works such as x*0=0. This does not seem to me to be logical. 0 is not a number rather it represents the absence of any value - it is nothing. In physics when something is acted upon by nothing then nothing changes but in math when x is acted upon by nothing (x*0) then x disappears (x*0=0)? How does x become nothing when nothing has acted on it? By logic x+0=x, x/0=x, x*0=x and 0/0=0.
