Usually just the final answer.

What if the number I have to add is like 5.6788543465?

anonymous · Answer

Type that all into the calculator?

luffingsails · Answer

That is what I would suggest. Are there anymore specific instructions? If it just says round the answer then that is all that I would round. Everything else would be exact.

anonymous · Answer

It just says "Round your answer to the nearest tenth,hundredth, thousandth.." so on..

Im in a trig class and I always get confused if I should round the number or keep it exact throughout the problem. Then just round the final answer.

anonymous · Answer

You should keep answers in intermediate steps as exact as possible, otherwise you'll get "roundoff" error.  It shouldn't be too significant as long as you keep 4 or 5 decimal places, but it can build up if you're doing a lot of calculations.

Thanks! I usually keep it to 4 or 5 decimal places then round my final answer to what it ask for. 

Just wanted clarification!
