There are five rules for identifying significant figures. 1) Non-zero digits and zeros between non-zero digits are ALWAYS significant. 2) Leading zeros (zeros at the beginning of numbers) are NOT significant. 3) Zeros to the right of all non-zero digits are only significant if the decimal point is shown. If the decimal is ABSENT start counting significant digits from the first non-zero on the ATLANTIC …

We convey our uncertainty in measured quantities by abiding by the rules of significant figures. Significant figures in a measurement include all of the digits that are known precisely plus one last digit that is estimated. Non-zero digits are always significant. 103.230002. Zeros between two other significant digits are always significant.

The starting values only have three significant figures each, so round the answer to three significant figures, 16.1. When adding and subtracting values, find the smallest decimal place that all values have in common and are significant and that is the last significant decimal place in your answer.
