When adding or subtracting numbers with significant figures, the answer should be rounded to the least number of decimal places in the original numbers. This ensures that the final result is accurate and reflects the precision of the original data.
When subtracting numbers with significant figures, the result should be rounded to the same number of decimal places as the number with the fewest decimal places. This ensures that the final answer is accurate and reflects the precision of the original numbers.
When multiplying or dividing numbers with significant figures, the result should have the same number of significant figures as the factor with the fewest significant figures. Round the final answer to match this rule.

When multiplying numbers, the result should have the same number of significant figures as the number with the fewest significant figures.
When multiplying numbers, count the number of significant figures in each number being multiplied. The result should have the same number of significant figures as the number with the fewest significant figures.
When subtracting numbers with significant figures, the result should be rounded to the same number of decimal places as the number with the fewest decimal places. This ensures that the final answer is accurate and reflects the precision of the original numbers.
When dividing numbers, the result should have the same number of significant figures as the number with the fewest significant figures in the calculation. Round the final answer to match the least number of significant figures in the original numbers.
When multiplying or dividing numbers with significant figures, the result should have the same number of significant figures as the factor with the fewest significant figures. Round the final answer to match this rule.
When multiplying numbers with significant figures, count the total number of significant figures in each number being multiplied. The result should have the same number of significant figures as the number with the fewest significant figures. Round the final answer to that number of significant figures.

When multiplying numbers with significant figures, round the final answer to match the number with the least significant figures in the original numbers.
When multiplying numbers, the result should have the same number of significant figures as the number with the fewest significant figures.
When multiplying numbers, count the number of significant figures in each number being multiplied. The result should have the same number of significant figures as the number with the fewest significant figures.
The answer will usually depend on the number of significant figures in the numbers from which there numbers were derived.
Significant figures are important for science, they tell how certain you are of a certain value. The rules for significant figures are as follows: If it is a decimal number, look at the first number on the left. If it is not zero, start counting the amount of numbers, and that's how many significant figures you have. For example, 7.495 has 4 significant figures. If it is zero, keep going until there is digit larger than zero, and start counting the numbers until the end. However many numbers there are, that's how many significant figures you have. For example, 0.000331 has 3 significant figures. If the number does not have a decimal, start from the right and if the number is not zero, start counting numbers and that's how many significant figures you have. For example, 93847 has 5 significant figures. If it is zero, the first significant figure will be the first non-zero digit. For example 3873000 has 4 significant figures. When you add or subtract some numbers, the amount of significant figures the answer should be expressed in depends on the number with the least amount of decimal places. For example, 4.398 + 5.2 = 9.6 You express the answer to the lowest number of decimal places a value you are adding or subtracting has. When you multiply or divide numbers, the answer is expressed to the lowest amount of significant figures that the values have. For example: 55 x 7 = 400 (when expressed with correct significant figures)
The least number of significant figures in any number of the problem determines the number of significant figures in the answer.
