Significant figures are the representative digits that make up the value of an uncertainty, excluding the zeros to the left, indicating the precision of that measurement, where the last represented digit is uncertain. Zeros to the right are significant.
Significant figures are the representative digits that make up the value of an estimate, excluding the zeros to the left, indicating the precision of that measurement, where the last represented digit is uncertain. Zeros to the right are significant.
Significant figures are the representative digits that make up the value of the deviation of a measurement, excluding the zeros to the left, indicating the precision of that measurement, where the last represented digit is uncertain. Zeros to the right are significant.
Significant figures are the representative digits that make up the value of a quantity, excluding the zeros to the left, indicating the precision of that measurement, where the last represented digit is uncertain. Zeros to the right are significant.
Significant figures are the representative digits that make up the value of the error of a measurement, excluding the zeros to the left, indicating the precision of that measurement, where the last represented digit is uncertain. Zeros to the right are significant.

Significant figures, or sig figs, are the representative digits that make up the value of a measurement or calculation. They indicate the precision or certainty of a number. The rules for determining significant figures are as follows: 1. Non-zero digits are always significant. For example, in the number 345, all three digits are significant. 2. Zeros between non-zero digits are also significant. For example, in the number 506, all three digits are significant. 3. Leading zeros (zeros to the left of the first non-zero digit) are not significant. For example, in the number 0.045, only the digits 4 and 5 are significant. 4. Trailing zeros (zeros to the right of the last non-zero digit) are significant if they are after a decimal point. For example, in the number 10.00, all four digits are significant. 5. Trailing zeros that are not after a decimal point may or may not be significant. For example, in the number 200, it is unclear whether the zeros are significant or not. To remove this ambiguity, scientific notation can be used. For example, 2.00 x 10^2 indicates that all three digits are significant. Remember that significant figures are important for maintaining the appropriate level of precision in calculations and measurements.
