Question

Thor is at the lowest point of Asgard whichis 280 feet below sea level (-280 ft.). He flies tothe highest point 520 feet above sea level(520 ft.). How far did he fly? Answer in acomplete sentence.

Answer 1

Addition of negative numbers

We have that:

We want to find how far did he fly. This means, we want to find the distance between -280 ft and 520 ft. (Which is 520 ft + 280 ft = 800 ft)

In order to find it out we substract them (we substract the first measure from the second):

520 - (-280)

Since - (-280) = +280, then

520 - (-280) = 520 + 280

= 800

Answer: he flied 800 ft
