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
