Significant figures are the digits in a number that contribute to its precision. The rules include: all non-zero digits are significant; zeros between significant digits are significant; leading zeros are not significant; trailing zeros in a decimal number are significant; and in whole numbers without a decimal point, trailing zeros are not considered significant. When performing calculations, the result should be reported with the same number of significant figures as the measurement with the least significant figures involved in the calculation.

The figure 18.03 has a total of four significant numbers
They are 4 significant DIGITS, not numbers! It is only 1 number.
All numbers are significant.
When multiplying or dividing numbers, the result should have the same number of significant figures as the factor with the fewest significant figures. When adding or subtracting numbers, the result should have the same number of decimal places as the number with the fewest decimal places.
0.5 has one significant figure. The zero is simply a place holder to indicate the position of the decimal point. Refer to the related link for rules for significant figures.
3, one of the rules is counting the Zero between none zero numbers
If two numbers have m and n significant digits, respectively, then then product can have at most m+n. However, the normally it is the minimum of m and n.

231.57 has five significant figures/numbers. All the numbers in 231.57 are significant.
When adding or subtracting numbers, the result should have the same number of decimal places as the number with the fewest decimal places. When multiplying or dividing numbers, the result should have the same number of significant figures as the number with the fewest significant figures.
All nonzero numbers are significant.
Three. All nonzero numbers are significant, and any zeros in between significant numbers are significant.
Salient rules means those rules likely to have a significant effect.
When multiplying numbers with significant figures, round the final answer to match the number with the least significant figures in the original numbers.
