The additive inverse are basically opposite numbers. When u add a number to its additive inverse, it equals 0. Example : -5 and 5.....2 and -2......4 and -4....etc. A hot air balloon ascends 2000 ft from the ground and then descends 2000 ft.........2000 - 2000 = 0 Noa hiked 2 mi up a mountain trail and then hiked 2 mi down the trail....2 - 2 = 0
