Problem 9Q

How do we determine significant figures in calculations involving both addition/subtraction and multiplication/ division?

Solution: Here, we are going to explain the rule for determining significant figures in calculations involving both addition/subtraction and multiplication/ division?

Step1:

If a calculation involves a number of steps, the result should contain the same number of significant figures as that of the least precise number involved, other than the exact numbers.

Step2:

For example, for the calculation 943 x 0.00345 +101, the first two numbers are to be multiplied initially as follows:

943 x 0.00345 = 3.25335 = 3.25.

According to the rules of multiplication of significant figures, the answer has to be reported up to three significant figures. So, the correct answer is 3.25 for the above multiplication. Upon further addition, the final answer may be calculated as:

3.25

+    101.

104.25

Since, the number having the least decimal place is 101., therefore, the final result after adding should also have digits up to zero decimal place. Thus the final result will be 104.
