How do you add number using significant digits? - Answers

Adding numbers using only the significant digits can introduce inaccuracies, for example if you are adding pi ten times using 4 decimal places of pi the answer is 31.416 but the right answer is 31.4159 . . Subtracting can give quite bad errors especially when two nearly equal numbers are subtracted. So for subtraction it's best to use more significant figures and round the answer to the required number of digits afterwards.
