numbers: significant figures
Significant Figures is a way of rounding.
POSITIVE
EG1: 4602 to 1,3 sf
We look at the highest value of the number
4602 to count the significant figure you need to do.
1 sf= 5000 as you would round it like normal numbers.
3 sf= 4600.
NEGATIVE
0.008434 to 2 sf
EG2: You round with the highest place value.
0.008434
You would start with the 8 because it is the highest place value except zero.
Then, calculate the significant figure.
0.008434
=0.0084
