Significant. In maths, we usually call it significant number.

I thought it was significant figure... which would explain what the 'f' stands for.

Depending on what topic in Maths you're doing, it can mean one of two things:
1. Scale Factor
2. Significant Figure

That's what I have learnt/been told.
Hope this helps!

Scale Factor
(e.g. enlarge by scale factor 2. this means that you would double all lenghts!)

it means signifigant figure been learning it recently.. you would get asked what is 1sf of a number.

if you have a number-

56,7456

the answer for 1sf would be 60,0000
the answer for 2sf would be 57,0000

but if the number was-

000678

and you got asked what is 1sf... zero is not a signifigant figure and any number other than one is! So the answer for 1sf would be:
700 you dont need to include the zeros at the front.
Hope this helps

please can someone explain what s.f. stands for? i'm confused :/  This is significant figures, this simply means what it says

1. if your given a number (example) 22.34567788 and your told to write it to 3 significant figures is simply means you are to re write it with only the first 3 figure's or numbers in this case the anser would be
22.3 as they are the first three significant figures

S.F STAND'S FOR SIGNIFICANT FIGURES

HOPE I HELPED

s.f. stands for significant figures which means in a decimal figure (number) for example any number other than zero is a significant figure however zeor can only be a significant figure only if they are in the middle of two numbers which are not zero.

please can someone explain what s.f. stands for? i'm confused :/  s.f. stands for significant figures and they are non zero numbers in a no. or a decimal. The only acception a zero to be a signifcant figure is if the zero is inbetween two non-zero digits or figures.

it means significant figure which is a way of rounding eg. if you had to round 3.56749 too 2 significant figures it would be 3.57 as the 7 after the 6 is over 5 which means you have to round up hope this helps

Significant figures. It is when you round the number before or after the decimal point. But you can't cound zero as a significant figure- only digits from one to nine. But if this is confusing, I'll give you an example.
What is £9854.56 to 2s.f?
£99
Solution:
The first two digits are nine and eight.
They are both between one and nine so that means you round it to those.
What there is a five behind it.
According to 'rounding' that means you have to raise £98 to £99.

An s.f. is a significant figure
so in the number 123
1 would be the first s.f.
2 would be the second s.f.
and 3 would be the third s.f.
in decimals 0 doesn't count unless there is a larger figure before it
so in 0.0123 1 would be the first s.f.
but in 0.1023 the second s.f. would be 0
Hope this helps

S.f can sometimes mean Scale Factor though usually it stands for 'significant figure.' A scale factor is sort of like the ratio, its how much bigger or smaller the shape's side or area has been changed to. A significant figure is simply a number, normally with an exact amount of digits after the decimal place.

Actually, that is more commonly known as 'd.p' standing for 'decimal places'- and these are the numbers that come AFTER the decimal point. :D
