A x B =
B x C =
A x C =
B X A =
A x A =
C x C =

Answer 1

$A * B = \{(3,-2),(3,4),(5,-2),(5,4)\}\\B * C = \{(-2,0),(-2,1),(-2,3),(4,0),(4,1),(4,3)\}\\A * C = \{(3,0),(3,1),)(3,3),(5,0),(5,1),(5,3)\}\\B * A = \{(-2,3),(-2,5),(4,3),(4,5)\}\\A * A = \{(3,3),(3,5),(5,3),(5,5)\}\\C * C = \{(0,0),(0,1),(0,3),(1,0),(1,1),(1,3),(3,0),(3,1),(3,3)\}$
