Introduction

When performing calculations in chemistry, it’s important to use significant figures to ensure that your results are accurate and precise. Significant figures reflect the precision of the measurements used in calculations. In addition and subtraction, the way you report significant figures is determined by the number of decimal places in the measured values.
