Thanks again...:-)

There aren't six rules here but these three will do it.

When it comes to determining significant figures, there are generally three rules that you need to follow:

1. Non-zero digits are always significant: Any non-zero digit in a number is always considered significant. For example, in the number 1234, all four digits (1, 2, 3, and 4) are significant.

2. Zeroes between non-zero digits are significant: If there are zeros between non-zero digits, they are also considered significant. For example, in the number 10.05, all four digits (1, 0, 0, and 5) are significant.

3. Leading and trailing zeros may or may not be significant: Leading zeros, which are zeros at the beginning of a number before any non-zero digit, are not significant. For example, in the number 0.005, only the digits 5 are significant. Trailing zeros, which are zeros at the end of a number after any non-zero digit, may or may not be significant depending on how they were obtained. For example, in the number 150, the trailing zero is considered significant since it implies additional precision, but in the number 150.0, the trailing zero is significant because it appears after the decimal point.

These rules are just a general guideline, and there may be additional considerations and exceptions depending on the context or specific calculations being performed. It's always a good idea to consult your textbook, teacher, or trusted resources to ensure you are applying the rules correctly.
