Some numerical questions have multiple parts that require you to enter estimated or The kind of answer that is expected should Numerical questions that check significant figures require you both to calculate theĬorrect answer and to specify that answer using the correct number of significantĭigits, for example, 2.3e4 to indicate 2 significant digits. Answering Numerical Questions That Check Significant Figures.Many different unit names and abbreviations can be used in numerical questions The kind of answer that is expected should be clear from the question. Numerical questions with units require you to enter both a number and a unit for theĪnswer, for example, 10 inches. Questions, classes, or instructors might require greaterĪccuracy, and will usually inform you if that is the case.
