What number is 1 position to the left of the orange dot? The distance between adjacent tick marks is 1.
−4 1 0

We know where −4 is on this number line because it is labeled.

Numbers to the left of −4 are smaller, while numbers to the right of −4 are bigger.

We need to find the number represented by the blue dot, which is 1 position to the left of the orange dot.

Starting from −4 , we move 4 to the right to reach the blue dot.

Thus, the blue dot represents the number 0 .
