What are signiflicant figures?

Answer 1

Significant figures are the digits in a number that contribute to its precision, including all non-zero digits, any zeros between significant digits, and trailing zeros in decimal numbers. They help convey the accuracy of measurements and calculations in scientific and mathematical contexts. For example, in the number 0.00452, there are three significant figures: 4, 5, and 2. Proper use of significant figures ensures that results reflect the precision of the data used in calculations.
