Significant Figure Rules for Logarithms • Things to remember: significant figures include all certain digits and the first uncertain digit. There is always some uncertainty in the last digit. • Regular sig fig rules are guidelines, and they don’t always predict the correct number of significant figures.

Rules for significant figures in our own measurements: If we are certain that a digit in a number is correct, then it is a significant figure. As we go from left to right in a number, the first digit we come to that has any uncertainty at all is the last significant figure that we report. This first uncertain digit has some value
