    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.

    It's not "acted upon", it means the value zero times, which is why the answer is always 0.
    2 x 2 means 2 twice (4), 2 x 1 means 2 once (2),and 2 x 0 means 2 0 times, which is 0.

    Does that make more sense?
