See more If every element of set A is also in B, then A is described as being a subset of B, or contained in B, written A ⊆ B, or B ⊇ A. The latter notation may be read B contains A, B includes A, or B is a superset of A. The relationship between sets established by ⊆ is called … See more WebFirst we specify a common property among "things" (we define this word later) and then we gather up all the "things" that have this common property.
