Is 6 the total number of subsets of A B C?

No


Why does a set containing n element have 2n subsets?

I presume you meant 2^n (2 raised to the nth power), not 2*n (2 times n). That's answers.com's character set problem again (I trust, giving you the benefit of the doubt). The answer is that for each of the n elements, it is either in any particular subset or it isn't. Which elements are in and which are not in a subset defines the subset. So for example, if n is 3, say a, b, and c, there are 2 sub-collections of the set of all subsets: those containing a and those not containing a. In each of those sub-collections, there are 2 sub-collections based on whether they contain b, for a total of 4 (2*2) sub-collections. Finally, of each of these 4, there are 2 subsets: those containing c and those not containing c, for a total of 8 (2*2*2 or 2^3) subsets. Got it?


To find biggest of three number?

Let the numbers be A,B and C and assume that A ≠ B ≠ C 1) Subtract B from A. If the result is a positive number then A > B otherwise B > A. 2) Subtract the greater of A and B from C. If the result is a positive number then C is the largest number otherwise the subtrahend (either A or B) is the largest number.


Answer in finding the formula of number of subsets?

i don't know the formula but it is if the formula was for instance a,b,c,d,e,f that could be one subset but f,e,d,c,b,a couldn't be because you have to picture them like floating numbers in a circle they can be in any order so all of the combomatins of a,b,c,d,e,f are just one but theen you have to count b,c,d,e,f as on and so on and so forth there are about....... under100 or over 700 figure it out!


How do you check subtraction?

If any number B is subtracted from a number A to give C, then C+B =A If A - B = C then B+C = A Eg 7 - 2 = 5 Hence 2 + 5 = 7
