a set of subsets that have the following two characteristics: a) the subsets are disjoint and b) the union of the subsets is equivalent to the original set
elementary fraction
A/B with A parts of one or more sets each of which have been partitioned into B equal parts, where A and B are whole numbers and B can't equal 0
a comparison of two sets of the following form: For every A elements in the first set, there are B elements in the second set
If not p, then not q.
