Answer:

Because it is 3 units to the left of 4 on a horizontal number line.

Explanation:

On a number line

  • Adding a positive number means moving to the right
  • Adding a negative number means moving to the left

Adding on the number line.

Add 4 + (-3)

Step 1. Find 4 on the number line  

Start at 0 and move 4 units to the right (see Image below).

This takes you to 4.

Step 2. Add (-3)

Start at 4 and move 3 units to the left.

This takes you to -1.

∴ 4 + (-3) = -1
