Algebra 12 - Binary Relations

The lecture introduces the concept of binary relations, explaining how ordered pairs can represent relationships between elements of two sets. It uses examples with sets A and B, comparing binary relations to Cartesian products. The lecture also discusses binary relations within a single set and visual representations in the XY plane, highlighting that binary relations are subsets of Cartesian products.
