Express the result of the following calculations to the appropriate number of siginficant figures:
0·58 + 325·65 = 324·23 (Actual result)
While carrying out addition of a number of terms, the result should be reported to the same number of decimal places as that of the term with the least number of decimal places. In the present case, both the given numbers have two decimal places, therefore, the reported sum should be only two decimal places after rounding off.
∴ Correct sum = 325·23
