Rounding with basic calculator

Since we don't have a scientific calculator for tests and quizzes, should we round to a few decimal points after each calculation since the basic calculator can't store the numbers?

We are allowed to use scientific calculators. We are not allowed to use graphing calculators.

It's always good to leave a couple of decimal points when computing your answer, as it will get as close to the real answer as possible, however, your final answer should include the correct amount of sig figs.

I asked one of the T.A.'s this question and he said that as long as in the steps of your calculation, you use more decimals than the required amount of sig figs, then you should be able to receive the correct answer when rounding at the end.

We are allowed to use scientific calculators. When doing calculations, I usually leave 3 or 4 digits after the decimal and then apply sig figs for my last answer.

One of the TA's I asked about sig figs said that it wasn't too big of a deal as long as all of the numbers in your answer were consistent in the number of sig figs used!

Use the "Ans" key on your calculator whenever possible. We're allowed to use scientific calculators but not graphing calculators, so you should be able to store values. Also, I generally leave at least 5 numbers after each decimal point (for each step) and apply sig figs at the very end.
