i noticed that rounding to 2 places vs 3 places can result in quite different answers...i heard that the grader will actually calculate everything based on what's written down in the answer sheet. but however, if i have a number in my calculator, say 1.689848879. i rounded to 1.69. but i still use the unrounded number (1.689848879) for the rest of the calculation. the answer would be different from using 1.69. Wonder how you guys normally do in such situation? do you punch in 1.69 in the calculator for the following calculation?
How many decimal places are you rounding?
