Use the addition principle if we can break down the problems into cases , and count how many items or choices we have in each case. The total number is the sum of these individual counts. The idea is, instead of counting a large set, we divide it up into several smaller subsets, and count the size of each of them. The cardinality of the original set is the sum of the cardinalities of the smaller subsets. This divide-and-conquer approach works perfectly only when the sets are pairwise disjoint. To find the number of students present at a lecture, the teacher counts how many students there are in each row, then adds up the numbers to obtain the total count. When the sets are not disjoint, the addition principle does not give us the right answer because the elements belonging to the intersection are counted more than once. We have to compensate the over-counting by subtracting the number of times these elements are over-counted.
