If R is the set of all real numbers, what do the Cartesian products R $ times $ R and R $ times $ R $ times $ R represent?

1 Answer

The Cartesian product R $ \times $ R represents the set R $ \times $ R={(x, y) : x, y $ in $ R} which represents the coordinates of all the points in two dimensional space and the cartesian product R $ \times $ R $ \times $ R represents the set R $ \times $ R $ \times $ R ={(x, y, z) : x, y, z $ \in $ R} which represents the coordinates of all the points in three-dimensional space.
