Significant Figures
Significant figures, also known as significant digits, are a crucial concept in mathematics and science. They represent the precision and accuracy of a measured or calculated value. In any numerical value, significant figures are the digits that carry meaning or contribute to its precision. Understanding significant figures is essential for proper measurement and calculation, as they dictate the level of uncertainty in a value. Whether in laboratory experiments, engineering designs, or financial analyses, recognizing and applying significant figures ensures the integrity and reliability of data and results.
