Key Concepts

Significant Figures

Significant figures are the digits in a number that contribute to its precision. This includes all non-zero digits, any zeros between significant digits, and trailing zeros in the decimal portion. When performing calculations, the result should reflect the precision of the least precise measurement, ensuring that the final answer is reported with the correct number of significant figures.

Division in Scientific Calculations

In scientific calculations, division involves determining how many times one number is contained within another. When dividing two numbers, the result should be rounded to the same number of significant figures as the measurement with the fewest significant figures. This ensures that the precision of the result is consistent with the least precise measurement used in the calculation.

Rounding Rules

Rounding rules dictate how to adjust a number to reflect the appropriate number of significant figures. If the digit to be dropped is less than five, the last retained digit remains unchanged; if it is five or greater, the last retained digit is increased by one. This process is crucial in ensuring that the final answer is both accurate and appropriately precise.
