Significant Figures |
1. Any nonzero digit is significant 2. Zeros between nonzero digits are significant 3. Zeros to the left of the first nonzero digit are not significant 4. Zeros to the right of the last nonzero digit are significant if a decimal is present. 5. Zeros to the right of the last nonzero digit in a number that does not contain a decimal point may or may not be significant. |

|
Significant Figures Addition and Subtraction |
the answer cannot have more digits to the right of the decimal point than any of the original numbers. |
|
|
Significant Figures Multiplication and division |
The number of significant figures in the final product is determined by the original number that has the smallest number of significant figures. |
