What does the expression-3 + (-2) represent

Question

The ship moves (up or down) 3 and then ( up or down) 2

Answer 1

The expression \(-3 + (-2)\) represents a total movement of 3 units down, followed by an additional 2 units down.

In this context:

• The \(-3\) indicates a movement of 3 units down.
• The \(-2\) indicates an additional movement of 2 units down.

So, the overall movement can be understood as starting from a position and moving down 3 units, then moving down another 2 units, for a total movement of: \[ -3 + (-2) = -5 \] This means the ship ends up 5 units down from its starting position.
