rules of operation sign of numbers
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.
5 significant figures.
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.
rules of operation sign of numbers
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.
In general, the rules for significant figures are: Non-zero digits are always significant. Zeros between non-zero digits are significant. Leading zeros (zeros to the left of the first non-zero digit) are not significant. Trailing zeros in a number with a decimal point are significant; without a decimal point, they may or may not be significant.

Answer: There are six. Answer: There is no such thing as "significant numbers". I assume you mean "significant digits". All digits are significant in this case - a zero (or more than one zero) between other digits is always significant.
