Hi, everyone. I'm practicing Cartesian products and wanted to see if I was doing this correctly. Here's the problem
Let A = {x, y, z}, B = {a, b}, C = {1, 3},
Find B x (C x A) (the x denotes multiplication)
Now wouldn't B x (C x A) = B x C x A?
Then we would have:
B x (C x A) = B x C x A = {(a, 1, x), (a, 1, y), (a, 1, z), (a, 2, x), (a, 2, y), (a, 2, z),
(b, 1, x), (b, 1, y), (b, 1, z), (b, 2, x), (b, 2, y), (b, 2, z)}
Is this right?
