# Thread: Having trouble multiplying more than two sets together

1. ## Having trouble multiplying more than two sets together

{1, 2} x {3, 4} = {(1, 3), (1, 4), (2, 3), (2, 4)}

but what if there's another set?

A x B x C = ???

if it were:

{1, 2} x {3, 4} x {5, 6}

how do these sets come together to give the cartesian product?

2. Hello,

The cartesian product of n sets gives all the possible n-tuples, formed by 1 element of each.

So :
{1, 2} x {3, 4} x {5, 6} = {(1,3,5) , (1,3,6) , (1,4,5) , (1,4,6) , (2,3,5) , (2,3,6) , (2,4,5) , (2,4,6)}

$\{ 1,2\} \times \{ 3,4\} \times \{ 5,6\}$ $= \left\{ {(1,3,5),(1,3,6),(1,4,5),(1,4,6),(2,3,5),(2,3,6),( 2,4,5),(2,4,6)} \right\}$
