I don't know if that's what you have in mind, but if A and B are sets of elements that can be summed, say real numbers, we define A + B = {a+b | a is in A and b is in B}. Therefore, A +B + C = {a +b +c | a is in A, b is in B, c is in C} and so on.

the addition of sets is not defined. u can find their union, their intersection etc. but u can't add or substract them.
