Example 4

easy
A submarine is at −35-35 meters. It rises 1212 meters and then sinks 77 meters. What is its final position?

Solution

  1. 1
    Start at −35-35 and rise 12 meters: −35+12=−23-35 + 12 = -23.
  2. 2
    Then sink 7 meters: −23−7=−30-23 - 7 = -30.

Answer

−30 meters-30\text{ meters}
Negative numbers model positions below a reference level. Moving up adds, and moving down subtracts, even when the starting point is already negative.
