When we add a positive value, we move to the right on the number line. When we add a negative value, we move to the left.

Arrows to the left equivalently mean adding a negative number and subtracting a positive number of the same magnitude. Arrows to the right equivalently mean adding a positive number and subtracting a negative number of the same magnitude.
