Difference of the product of sets
Topology
Sets and Functions (XLII)
Functions
Let X and Y be non-empty sets. If A_1 and A_2 are subsets of X, and B_1 and B_2 subsets of Y.
Show that
(A_1×B_1) - (A_2×B_2) = (A_1 - A_2)×(B_1 - B_2)
U(A_1 intersection A_2)×(B_1 - B_2)
U(A_1 - A_2)×(B_1 intersection B_2)

Solution Summary
This solution is comprised of a detailed explanation of the properties of the products of sets.
It contains step-by-step explanation of the following problem:
Let X and Y be non-empty sets. If A_1 and A_2 are subsets of X, and B_1 and B_2 subsets of Y.
Show that
(A_1×B_1) - (A_2×B_2) = (A_1 - A_2)×(B_1 - B_2)
U(A_1 intersection A_2)×(B_1 - B_2)
U(A_1 - A_2)×(B_1 intersection B_2)
