Answer:
|7| + |-2| | +|5| + |-8|=
Explanation:
We want to find the total number of spaces traveled, it doesn't matter whether they are forward or backward.
We moved 7 spaces right then 2 spaces left then 5 spaces right then 8 spaces left. The total spaces are just the number of spaces, not whether they were left or right so we take the absolute value
|7| + |-2| +|5| + |-8|=
