A zero on its own does mean nothing. But a zero has an important place to play in spacing in maths, as in 1,000 for one thousand, or 0.02, and so on.
Zero is nothing which equals nothing :)
Zip = nothing/zero Nix = nothing/zero Nil = nothing/zero
nothing, its a gaming system, nothing sexually involved
We need "0" because we need something to represent "nothing". Without 0 we would have to keep inventing new symbols for larger and larger numbers. Using zero we don't. Hope this helps :)
Moderately means average;ordinary;nothing special.
