Rules for Using Significant Figures in Mathematical Operations

If the answer has too many decimal places, round to the number of sig figs it should have. For example, 12 / 3.00 = 4 (4.0 12 has two significant figures and 3.00 has three, so the answer should only have two. For example, 3.20 x 5.04 = 16.128 (16.1 ................
