counting significant figures

a.) a nonzero digit
b. A zero between nonzero digits.
c.) a zero at the end of a decimal
1 number is not significant if it is 2. a zero used as a place holder in a large number without a decimal point.

Multiplication and division

the final answer is written so it has the same number of significant figures as the measurement with the fewest significant figures.

addition and subtraction

the answer is written so it has the same number of significant figures as the measurement with the fewest decimal places
