Two ways of answering: Nearest ten to 16 = 20, nearest ten to 13 = 10 so sum of neaest tens = 20 + 10 = 30 Alternative: 16 + 13 = 29. Nearest ten to 29 = 30. In this case the two answers agree, but they need not. eg 14 + 13. Nearest at first step gives 10 + 10 = 20 Nearest at last step gives 14 + 13 = 27 which goes to 30.
