Question
Chapter 1, Problem 1.42P
Interpretation Introduction
Interpretation:Exact number should be defined. Also, different treatment of these numbers from other numbers in calculation should be explained.
Concept introduction:Numbers in any calculation can be either exact or inexact. Exact numbers are numbers with high certainty while inexact numbers are calculated with some level of uncertainty.
