The least number of significant figures in any number of the problem determines the number of significant figures in the answer.
Measurements need to be specific so we use significant digits.
Any measurement may have two significant digits.
When using significant digits, the product has only the number of significant digits as the lowest number in the factors. "20" has two significant digits and "310" has three. Therefore, the product has to have two significant digits. 310 × 20 = 6200 6200 already has 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

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.

The number of significant digits is the length of the numerical string from the first to the last non-zero digits in a number.The number if significant digits in 9807600, or 0.0012021 is 5.
To determine the number of significant digits in the result of the operation ( (40200.0 \times 0.000240) - 2.778 ), we first evaluate the multiplication. The term ( 40200.0 ) has 6 significant digits, and ( 0.000240 ) has 3 significant digits, so the product will have 3 significant digits (the least in the multiplication). When subtracting ( 2.778 ) (which has 4 significant digits), the final result should be reported to the least precise decimal place of the subtraction, which is determined by the number with the least decimal places (in this case, ( 2.778 ) has 3 decimal places). Therefore, the final result will have 3 significant digits.
