The rules for identifying significant figures when writing or interpreting numbers are as follows:
All non-zero digits are considered significant. For example, 91 has two significant figures (9 and 1), while 123.45 has five significant figures (1, 2, 3, 4 and 5).
Zeros appearing anywhere between two non-zero digits are significant. Example: 101.1203 has seven significant figures: 1, 0, 1, 1, 2, 0 and 3.
Leading zeros are not significant. For example, 0.00052 has two significant figures: 5 and 2.
Trailing zeros in a number containing a decimal point are significant. For example, 12.2300 has six significant figures: 1, 2, 2, 3, 0 and 0. The number 0.000122300 still has only six significant figures (the zeros before the 1 are not significant). In addition, 120.00 has five significant figures since it has three trailing zeros.

The least number of significant figures in any number of the problem determines the number of significant figures in the answer.
In a numerical sense, 6.3 is equivalent to 6.30 because they both represent the same number, 6.3. The addition of the zero at the end of 6.30 does not change the value of the number. However, in terms of significant figures, 6.3 has two significant figures while 6.30 has three significant figures, which may be important in certain scientific calculations or measurements.
The least number of significant figures in any number of the problem determines the number of significant figures in the answer.
The accuracy of the measurement device determines the number of significant figures that should be retained in recording measurements.
When performing calculations with measurements, it is important to maintain the same level of precision as the least precise measurement to avoid introducing false accuracy. Using more significant figures in the final result than what was present in the original measurements can lead to misleadingly precise results. Therefore, limiting the number of significant figures in the final answer prevents suggesting a level of precision that was not actually present in the original data.
