Sophia: Adding and Subtracting Using Significant Figures

In this significant digits learning exercise, students review the rules of working with significant digits and then give the number of significant digits in the given measurements. This learning exercise has 30 problems to solve.

Selecting the proper measurement requires thought; for example, an odometer shouldn't be used to measure millimeters due to a lack of preciseness. An informative video from a Socratica playlist explains the importance of significant...

Are your lab results both accurate and precise? An interesting video lesson explains the difference between the two descriptions. Using error and percent error measurements, these descriptions become concrete and in turn leads to a...

This lesson will demonstrate how to add/subtract measurements and report the result to the correct number of significant digits. It is 2 of 3 in the series titled "Adding and Subtracting Using Significant Figures."
