Hi all,
I'm doing OCR AS Physics.
If I do a calculation and get a decimal answer of 14.5485, I'm a bit confused how to round this to, say, 3 SF.
My maths teacher says I should round it down to 14.5, but my Physics teacher rounds from the right, which would make it 14.6 (because the 8 takes the 4 up to 5, which rounds up to 14.6)
Any ideas? Which one's right?
Thanks!
Ryan
