[SOLVED] Significant Digits

I know how to do significant digits, but was wondering about answers involving multiple equations. If I find acceleration first, then find net force, should I wait to round the answer until the end?

a=vf-vi/t and then fnet=ma

To reiterate, should I keep acceleration long, or round it to complete the group of equations above?

Thank you very much!

Don't round off till the end!!!

Are you able to store values to letters on your calculator? I would suggest doing that if you can.
