Counting the Number of Part Sets

Basic Mathematics Formulas, SD, SMP, SMA, and Umum

To count the number of subsets there are two ways we can use:

1. Manual way

Manual way is by registering one by one its members. This method is suitable if the members of the set are small, if the members of the set are many then we will have difficulty to register all members of the subsets.

2. Quick Way

To master this fast way you have to master the factorial concept and the concept of combination (this concept will you get when you sit in high school).
