3

2 + 1

Show how to find the answer to −3 + 4 − 1 on a number line.

See parts (a) and (b) for help.

Rachel said that −4 −3 ends up being positive because two negatives always give a positive. Draw the problem on a number line, and then explain whether you agree or disagree with Rachel.

−1 + (−2) = −3

−7 + (−4) = −11

Do two negatives always make a positive?
