Explain how NOTHING is ZERO, but ZERO is more than NOTHING?

Nothing can be zero, but zero isn't nothing. If someone asks you if you have money and you say "I've got nothing!" when you actually don't have a cent, then you have zero money. However, zero is a number, so it itself is something, therefore more than nothing. So technically, you do have something.

When zero is on a number line, you could classify it as nothing, but it is the number between 1 and -1. Hypothetically speaking, if you took the zero away, wouldn't the number line be the same?

Zero isn't positive or negative. The number zero on a graph, or in a coordinate can tell you where something is. Zero can be a word to describe if something is existent, or non-existent.

Okay, my brain hurts.

nothing means there is nothing around but zero could mean that there are zero of something but still have other stuff around
