Measurements need to be specific so we use significant digits.
Any measurement may have two significant digits.
Out of all the measurements used in the calculation, find the one with the least number of significant digits. This will be the limiting factor of how many significant digits the answer should have.
the precision of the answer must have the same number of significant digits as the measurement with the least significant digits- the site explains the rules and how to identify significant digits
Significant figures represent the precision of a measurement or calculation, indicating which digits are reliable and meaningful. They include all non-zero digits, any zeros between significant digits, and trailing zeros in the decimal portion. The use of significant figures helps convey the uncertainty in measurements and ensures that calculations reflect the precision of the data used. Properly applying significant figures is essential in scientific communication and reporting results accurately.
The least number of significant figures in any number of the problem determines the number of significant figures in the answer.

No, counting numbers you can ignore or say they have an infinate number of significant digits. By counting numbers I mean things you count, or non measurements, or numbers you wouldn't round to significant digits anyway . Measurements always have significant digits.
Significant figures and significant digits are terms used in numerical calculations to indicate the precision of a number. Significant figures refer to all the digits in a number that are known with certainty, including both non-zero digits and zeros that are between non-zero digits or at the end of a decimal. Significant digits, on the other hand, refer to all the non-zero digits in a number, excluding any leading or trailing zeros. In essence, significant figures provide a more accurate representation of the precision of a number compared to significant digits.

their both based on units of measure
The least number of significant figures in any number of the problem determines the number of significant figures in the answer.
