Sig figs with subtraction and division
Web(2) In multiplication and division, the result should be rounded off so as to have the same number of significant figures as in the component with the least number of significant figures. For example, 3.0 (2 significant figures ) 12.60 (4 significant figures) = 37.8000 which should be rounded off to 38 (2 significant figures). WebNo, because with addition (and subtraction) it isn't the significant figures that matter. In fact, this video isn't at all about significant figures. It's about decimal places (d.p). 1.26 went to 2 d.p. Whereas 102.3 only went to 1 d.p. As 1 d.p is less than 2 d.p. The answer can only go to 1 d.p. As you can see, significant figures don't come ...
