Answer:

Significant figures are an indicator of the certainty in measurements

Significant figures communicate the level of precision in measurements

Explanation:

As the number of significant figures increases the precision of measurement increases hence a number with 3 significant figures is more precise than a number with 2 significant figures. Also the certainty of measurement increases with the increase in the number of significant figures. A number with 4 significant figures is more certain than a number with 2 significant figures.
