Quizplus · Accepted Answer

When adding numbers with different numbers of significant figures, the final result should be rounded to the same number of significant figures as the number with the least significant figures. However, in some cases, the result of addition may have more significant figures than any of the numbers added, which occurs when the numbers being added have extra leading or trailing zeros. These zeros are considered significant when they are included in the calculation, resulting in a larger number of significant figures in the final result.
