Question

Find the cross product of and B:

A = {0, 2, 4, 6, 8}
B = {1, 3, 5, 7, 9}


Is there an easy way to do this?

Answer 1

A x B = {the set of all ordered pairs (a,b) where 'a' comes from set A and 'b' comes from set B}

Answer 2

If

A = {0, 2}
B = {1, 3}

then

A x B = { (0,1), (0,3), (2,1), (2,3) }

Answer 3

I know that way, but are there any simpler ways?

Answer 4

You can make a table

If A = {0, 2} and B = {1, 3}

then

Answer 5

Okay thanks.
