Addition and subtraction significant figures

    • How do you add significant figures?

      When adding significant digits, the amount of significant digits that will be in the final answer is determined by the number of significant digits present after the decimal place in the numbers we are adding. The final resultant value will have the same number of decimal place values as the addend with the least amount of decimal places.

    • What are the rules in dividing significant figures?

      The use of significant figures in case of multiplication follows the following rule: In this rule, we count the significant figures in each number, not the number of decimal places and when numbers are multiplied. The answer would have no more significant figures than the least approximated number.

    • What are the rules for SIG figs?

      Summary of The Rules for Sig Figs. Use as many digits as possible in intermediate calculations, but round to the appropriate number of ``sig figs'' for the final answer. When adding or subtracting, perform the operation as usual, but restrict your result by rounding to the smallest number of digits past the decimal in any operand. When...
