  ‹ Find solutions to compound inequalities and write those solutions using interval notation. Definition 1. The intersection of two sets is another set altogether, formed by the numbers common to both sets. We use the intersection symbol, \, to denote the intersection of two sets. Example: Suppose A = f10;11;12gand B = f10;20;30g. Then, A\B ...

  in this new subset. This is an example of the intersection of two sets. In particular, for sets A and B, the set A\B = fx : x 2A and x 2Bg is called the intersection of A and B. The intersection of A and B consists of all elements belonging to both A and B. The union of A and B is the set A[B = fx : x 2A or x 2Bg
