Pretend that you have a computer with base 10 with 4 digits in the significand )10. This computer rounds to zero (chopping) after each arithmetic operation. For example, the sum of 4.75 128.4 133.15 becomes 133.1. 7. 1.0 point Calculate the sum Grandom order): 128.4 2.165 32.15 0.3227 a 163.0 b) 162.9 c) 162.5 d) 163.0377 e) 162.8 f 161.7 Answer: 8. (1.0 point a) 163.0 b) 162.9

Solution

a) 128.4 + 2.165 = 130.565, this will become 130.5.
130.5+32.15 = 162.65 which becomes 162.6.
162.6 + 0.3227 = 162.9227 this will be 162.9.

The final answer is 162.9

b) 0.3227 + 2.165 = 2.4877 this becomes 2.4.
2.4+32.15 = 34.55, this becomes 34.5
34.5 + 128.4 = 162.9

The final answer is 162.9

c) 128.4 + 32.15 = 160.55, which becomes 160.5
160.5 + 2.165 = 162.665, which becomes 162.6

162.6+0.3227 = 162.9227, which becomes 162.9

The final answer is 162.9

d) The answer is a.
