Question

How much higher is 500 than -400 m

Answer 1

900m

Explanation:

All you have to do is find the difference between the two measurements

500 - (-400)

Then, two negatives create a positive:

500 + 400

= 900

Answer 2

900 m

Explanation:

500m is above zero

-400 m is below zero

500 steps to 0 and then 400 steps to -400

500+400 = 900

500 - (-400) = 900 m
