Understanding the Concept of Significant Figures

Significant figures is a fancy name for the representation of meaningful digits in a number. This concept also goes by the name sig figs or significant digits. It is used to indicate the degree of accuracy or precision in computation or measurement by counting numbers and decoding their meaning. Therefore, all the digits that add to a value’s accuracy, like beginning with the first non-zero digit and continuing through all subsequent digits, including trailing zeros, are included in significant figures.

For example, every digit in the number ‘3.14159’ has a purpose according to the definition of significant figures. The ‘3’ is significant because it establishes the scale of the value. The ‘1,’ ‘4,’ ‘5,’ and ‘9’ further fine-tune the measurement. Therefore, these digits add more detail to the number. The following ‘9’ is also significant because it indicates a degree of assurance in the value.

Rules Essential for the Calculations of Significant Figures

Calculation of significant figures begins with understanding the essential principles. The following points offer a quick peek at those principles: Determine all the significant digits in a number, including all non-zero digits and any zeros between them. For instance, in the number 6041, the digits ‘6,’ ‘0,’ ‘4,’ and ‘1’ are all significant.

Be mindful that all trailing zeros after a decimal point or to the right of the last non-zero digit are significant. For instance, all zeros in the number ‘8.00’ are important.

To ensure accuracy in computations of significant numbers containing mathematical operations, use the ‘addition-subtraction’ and ‘multiplication-division’ rules. For instance, in the case of ‘addition-subtraction,’ the outcome should be rounded to the same number of decimal places as the calculation’s least precise value. But for ‘multiplication-division,’ the result should have the same number of significant figures as the calculation’s least exact value.

Sig Figs Calculation Examples Involving ‘Addition-Subtraction’ and ‘Multiplication-Division’ Operations

To better understand the computation principles of significant figures, consider the following examples:

Addition-Subtraction

Calculate 15.76 + 2.3 and give explanations according to the rules of significant figures. By adding ’15.76’ and ‘2.3,’ we’ll get ’18.06.’ However, since ‘2.3’ has only one decimal place, it is essential to round off the result to one decimal place according to the principles of significant figures. Hence, the result of this problem will be ‘18.1.’

Multiplication-Division

Compute 4.2 × 3.00 and give interpretations according to the rules of significant figures. By multiplying ’4.2’ and ‘3.00,’ we’ll get ‘12.6.’ But since ‘3.00’ is the least precise number, it has three digits. Hence, according to the rules of significance, the result will be rounded to three significant figures. The final output of this problem will be ‘12.6.’
