How do I know when to give the correct decimal places or significant figures for my answers?(physics)
Thank you!
Eric :)

Ok , here's how it goes...
when times and dividing ,
follow the significant figures of the smallest decimal
IE.
9.001 x .01 = 0.09001 would be
0.090 (2 significant numbers according to 0.01)

When plus or minus,
follow the least decimal places of the numbers
1.0001 + 0.001 = 1.0011 would be
1.001 (3 decimal places as in 0.001)

So hope this help =_=
