Lab 1: Numbers (Significant Figures and Scientific Notation) .. Calculations. Assume all numbers are measurements. If the number of significant figures is ambiguous, assume the smallest number of significant figures. Write entire calculated result (up to at least 5 digits) and final answer with the correct number of significant figures. Remember that addition/subtraction rules differ from multiplication/division rules and to round 5.
