It depends upon how you got to the 12, for example: 28.6 - 16.6 = 12.0 Because each of the numbers that was used to get to the 12 had 3 significant figures, you should write the 12 with three significant figures also. However: 29 - 17 = 12 In this case, each of the numbers that was used to get to 12 had only 2 significant figures, so use only 2 significant figures in the 12.
It is: 11+13+17+19+23+29 = 112

If you mean how many significant figures it has, it has 3. As a number, has several interesting properties such as the sum of twin primes. The wikipedia article on 384 may help: http://en.wikipedia.org/wiki/384_%28number%29
Starting at the second digit after the decimal, if it is between 0 and 4, you round the first digit down. If it is between 5 and 9, you round it up. If the third digit is between 0 and 4, you round the second digit down. If it is between 5 and 9, you round the second digit up. Rounded to.......... 1 signifcant figure: .3 2 significant figures: .29 3 significant figures: .294 4 significant figures: .2943 5 significant figures: .29430
It is: 11+13+17+19+23+29 = 112
There is no decimal point in the number in the question so it is not possible to answer the question.
