non-zero digits are always non-zero digits are always significantsignificant
404= 3(because the zero counts here)404= 3(because the zero counts here)
RULES for SIG FIGSRULES for SIG FIGS1.1. Non-zero digits and zeroes between Non-zero digits and zeroes between
non-zero digits are always non-zero digits are always significantsignificant
404= 3(because the zero counts here 404= 3(because the zero counts here think of a sandwich) think of a sandwich)
686 = 3 (because all regular numbers 686 = 3 (because all regular numbers except zero…..always count)except zero…..always count)
