Question

Should 0 be on your number line? Explain.

Answer 1

Yes

Explanation:

That is where you start from. Before 1 is 0, so I would put 0 on your number line. Also, number lines have 0s on them. I don't think I ever saw a number line that doesn't have 0.

Hope I can help.

Answer 2

Yes it should, 0 is still a number even though it’s value is nothing. You can’t get to -1 without 0.
