Question

Can someone please help me with this problem? Use the number line to model the sum 2 + (-6). Here is my answer:
<---6---5---4---3---2--1--0--1--2--3--4--5--> Start at 2 and count backwards 6 points. Is this correct?

Answer 1

Yes, although I hope in the real number line you make a clear distinction between positive and negative.

Answer 2

Is there a way to make the clear distinction between positive and negative? Thanks.
