Thedifferences, a b, is obtained as follows:Start at b and move toward a. If you move toward the right, the difference is positive.If you move toward the left, the difference is negative.In other words, a b is the directed distance from b to a.Example 1 8 3 ?5 units right7 6 5 4 3 2 1 0 1 2 3 4 5 6 7 8 9So 8 3 5 (Of course, you already knew that!)Example 2 5 (2) ?7 units right7 6 5 4 3 2 1 0 1 2 3 4 5 6 7 8 9So, 5 (2) 7Example 3 2 5 ?7 units left7 6 5 4 3 2 1 0 1 2 3 4 5 6 7 8 9So, 2 5 732
