Really bone question - sorry!

(1/2) > >>

ivrytwr3:
OK, i'm a back to school adult and after a weeks intense course am about to sit IGCSE Math exams.  But, i have a really simple question i hope somoene can answer:

When the exam paper states "Give the answer to 3 significant figures, or if degrees, to one decimal place" - does this mean:

a.  Each part of your working out is rounded

or

b.  The overall answer is rounded?

Sorry  :-[

T.Q:
only the final answer

Amr Fouad:
NEVER Round your working..if you do you will lose accuracey in your final answer..in your working round to AT LEAST 5 s.f...

than do as T.Q said..
