Thanks Adam,

Here NinjaDevo gave a wonderful answer for 3-6

 

https://web2.0calc.com/questions/the-answer-to-the-expression-3-6-located-on-a-horizontal-number-line

 

 

I pulled this straight out of our sticky notes under "Great answers to learn from

 

 

So with any addition or subtraction you 

1) start on the number line at the first number.

2) Go left if you are subtracting (just like NinjaDevo did)

3) Go right if you are adding
