n. 1. (Mathematics) maths. a. a set the members of which are all members of some given class: A is a subset of B is usually written AâB. b. proper subset one that is strictly contained within a larger class and excludes some of its members.
Number of subsets of 9 distinct things is 29, the number of subsets of 10 distinct things is 210. The number of Proper subsets of a set is one less than the number of subsets because you need to exclude the set itself. So the number of proper subsets is 29 - 1 or 210 - 1 depending on how you define the Natural Numbers. (note that the null set â is a subset of every set).
