Concept explainers
To Explain:The way, the significant figures are determined in addition and multiplication.
Explanation of Solution
Introduction:
The number of digits in a certain value which hold importance in determining the level of accuracy of that value is known as significant figures.
To determine the significant figures in addition of measured values, the resultmust have the exact precision like the least most precise value used in the calculation.
Therefore, in the given sum of measures, the least precise value is a unit.
To determine the significant figure in multiplication, the resultmust have the exact number of significant figures like the measured value with the least mostnumber of significant figures.
As the least number of significant values is 2, the product is written with two significant figures:
