For example, there are 3 sig figs in 3500. The last zero (in the ones place) is not significant. When multiplying or dividing, the answer will have the same amount of sig figs as the value with the least number of sig figs. 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
