Question
Chapter 1, Problem 1.49P
Interpretation Introduction
Interpretation:
An exact number is to be defined and how they are treated differently from other numbers in a calculation is to be determined.
Concept introduction:
Significant figures of a number are the digits which carry meaningful contribution to its measurement resolution. The rightmost digit of the quantity is the most uncertain digit. The number of certain and uncertain digit in a quantity is considered as significant figures. The digit with a higher number of significant figures has a higher certainty of measurement.
