🛩️ Altitude Distance — Absolute Value & Distance

−6 m
+4 m
|submarine| = 6
|aircraft| = 4
Distance = 6 + 4 = 10 m
Submarine is farther from 0
📖 Worked Example:
|−6| = 6, because −6 is 6 units from zero on the number line.
Distance between submarine and aircraft crosses zero, so we add their absolute values:
|submarine| + |aircraft| = total distance.
absolute value distance from zero opposite signs
