We round off calculated numbers because there are fewer significant figures in the measured numbers, than there are digits that appear in your calculator display: If the first number to be dropped is 5 or greater, what should you do? just add a bunch of zeros and you will be fine it and all following numbers are retained the numbers are dropped and the value of the last retained digit is increased by 1 it and all following numbers are dropped
