## Understanding Significant Figures

Significant figures, also known as sig figs, are the digits in a number that hold important meaning when it comes to precision. They provide you with valuable information about the accuracy and reliability of a measurement.

When it comes to significant figures, there are a few important rules to keep in mind for accurate calculations. Non-zero digits and trapped zeros are important in significant figures for accurate calculations.

Additionally, trailing zeros, those at the end of a number without a decimal point, and exact numbers, like counting numbers, have an infinite number of significant figures.
