Answer:
D. -3 + 6
Step-by-step explanation:
Starting from zero, we move 3 units to the left. This gives -3.
We now change direction and move to the right 6 units. This gives +6.
Putting the two movements together gives
[tex] - 3 + 6[/tex]
The correct choice is D.
Note that moving to the left is considered to be negative while moving to the right is considered positive.
