3 significant figures.
5 significant figures.
6040 has 3 significant figures.
The simple rule is: no more significant figures than the least accurate of the values in the computation. For multiplication and division, the result should have as many significant figures as the measured number with the smallest number of significant figures. For addition and subtraction, the result should have as many decimal places as the measured number with the smallest number of decimal places. (Rounding off can be tricky, but that would be another thread)
When performing calculations involving significant figures in both multiplication and addition operations, ensure accuracy by following these steps: For multiplication and division, the result should have the same number of significant figures as the measurement with the fewest significant figures. For addition and subtraction, the result should be rounded to the same decimal place as the measurement with the fewest decimal places. By applying these rules, you can maintain the accuracy of your calculations involving significant figures.

When performing a logarithmic calculation involving significant figures, the number of significant figures in the result is determined by the number of decimal places in the original values being used in the calculation. The result should be rounded to match the original value with the fewest decimal places.
When performing mathematical operations with significant figures, the result should be rounded to the least number of decimal places in the original numbers. Addition and subtraction should be rounded to the least number of decimal places, while multiplication and division should be rounded to the least number of significant figures.
When adding or multiplying numbers, the result should have the same number of decimal places as the number with the fewest decimal places. For addition, the result should have the same number of significant figures as the number with the fewest significant figures. For multiplication, the result should have the same number of significant figures as the number with the fewest significant figures.
When performing calculations involving addition, the result should be rounded to the same decimal place as the least precise number being added. For multiplication and division, the result should have the same number of significant figures as the least precise number in the calculation.
The least number of significant figures in any number of the problem determines the number of significant figures in the answer.
The least number of significant figures in any number of the problem determines the number of significant figures in the answer.
The answer depends on what operations were used. There should normally not be more significant figures in the answer than in any of the numbers used in the calculation.
Students often struggle with determining the correct number of significant figures to use when adding or multiplying numbers. This can lead to errors in calculations and incorrect final answers. Additionally, students may find it challenging to properly round their final answers to the correct number of significant figures. Understanding the rules for significant figures and applying them correctly can be a common challenge for students in these types of problems.
To determine the correct number of significant figures in a calculation involving both addition and multiplication, follow these steps: Perform the addition or subtraction operation first, and count the number of decimal places in the result. For multiplication or division, count the number of significant figures in each number being multiplied or divided. The final answer should have the same number of significant figures as the number with the least number of significant figures in the calculation.
