An object moves from position X = -1.88 m to X = -4.27 m. What was its displacement? (Unit=m)

The answer should be -2.39 m.

Explanation:

The object starts at -1.88 m and ends up at -4.27 m. Using simple math, we can add -4.27 m and 1.88 m by making -1.88 m a positive position. If you do the math correctly, you will get -2.39 m. Now to test this, you can simply add -1.88 m and -2.39 m and your answer will be -4.27 m.
