From 2, you can go to either 8 or 5, so 8 is better (maximize you result by 3) so you calculate the first sum 8 + 2 = 10, From 4, you can go to either 5 or 9, so 9 is better (maximize you result by 4) so you calculate the second sum 9 + 4 = 13, From 6, you can go to either 9 or 3, so 9 is better again (maximize you result by 6) so you calculate the third sum 9 + 6 = 15. For each node there can be four ways that the max path goes through the node: Node only Max path through Left Child + Node Max path through Right Child + Node Sound like when you played the cassette tape with programs on it min value of 0'th.
