Question

Why is it incorrect to think that the more digits you represent in your answer, the more accurate it is?

Answer 1

it infact is

if you say 300m then it has one significant figure
if you say 312m then there are 3 significant figures in it!

Answer 2

I think he/she means that the more digits the less accurate, something like that

Answer 3

If you're measuring the length of a one meter long stick, 1.01 meters is considerably more accurate than 5.483722839403 meters. It's less *precise*, but more *accurate*.

Answer 4

Yeah, did mean the more digits the less accurate. Thanks Sam ('she' btw).
Thanks Jemurray, that makes sense.
