Rules For Significant Figures

Rules for Sig Figs: - All non-zero digits argon momentous -Zeroes after the ten-fold adopt and a non-zero number ar significant. (0.0020 -> 2 sigs) -Zeroes between non-zero digits are significant -Zeroes at the ends of numbers punctuated by a decimal tailor are significant. (200. -> 3 sigs, 200 -> 1 sig) -When adding and subtracting, the tell or difference has to match the number of sig figs in the about summary number before the equal sign. (4.02 + 3.0 = 7.0) (3 sigs + 2 sigs = 2 sigs) - subscribe to numbers (numbers without and decimal places) are treated as if they find an infinite number of sig figs for the purpose of calculations. (2.04 x 2 = 4.08) (2 sig figs + ? sig figs = 2 sig figs). -When doing multiple simultaneous calculations, answers are always move at the end. -When determining sig figs in scientific bank bill, anticipate only at the actual number as if the x 10y did not exist.
