Olaf is playing a game with his dad. He scored three times more points than his dad, who scored 7 points. How many points did they score in total?
Olaf scored three times more points than his dad, which means he scored 7 * 3 = <T>multiply(3, 7)=21 points.
So in total, Olaf and his dad scored 21 + 7 = <T>add(21, 7)=28 points.
