1. Annie has been asked to calculate 1.7 + 6/2. She claims the answer is 3.85. Do you agree? Explain why or why not.
Answer: I don't agree because 6/2 = 3, 1.7+3 = 4.7
2. Put brackets in the following expression to get the largest value possible. What problem solving strategy did you use? 3* 2.8 +6.4 /4.
Answer: (3*2.8) + 6.4 /4= 10
3*2.8 + (6.4 /4) = 10
3* (2.8 + 6.4) /4 = 6.9
