Question

Explain how you could use a number line to determine -5 -(-3)

What is the difference?

Answer 1

-2

Explanation:

Start on -5 on the left side of the number line, jump from -5 three times to the right of the number line since ( - - ) means to add. As you jump draw "bridges" and by the time you have completed the amount of jumps you have to do you'll end up with a difference of -2.
