I have a Chemistry question which should be very simple but I do not know what significant figures are.

Assuming the following numbers are measurements and using the rules for significant figures, determine the answer for the following calculation.

(15.5/42)*219.5=

1. 81.0059

2. 81.006

3. 81.01

4. 81.0

5. 81

The number obtained from the calculator is 81.00595238 should I just round or are significant figures something else entirely?
