Question

A. 3 + (-6)
B. -3 + (-6)
C. 3 + 6
D. -3 + 6

Answer 1

D. -3 + 6

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

`- 3 + 6`

The correct choice is D.

Note that moving to the left is considered to be negative while moving to the right is considered positive.
