In order to calculate how far is Jim away from his home, we represent the values by positive and negative.
If he ran away from home, the value is +
If he ran towards his home, the value is -
Jim ran 9.8 miles away from his home: +9.8
Jim ran 7.2 miles towards his home.: -7.2
Jim ran 4.6 miles away from his home: +4.6
Add all the values together to determine Jim's distance from home.
Jim's distance from home = 9.8 miles - 7.2 miles + 4.6 miles
Jim's distance from home = 4.6 miles
