Question

Write out all the different ways in which the elements
of the set {a, b, c} can be matched in pairs
with the elements of the set {@, &, %} if the order
in each pair is important. For example, the pair
(a, @) is different from the pair (@, a).

Answer 1

Let's see, this is somehow similar to my discrete mathematics course I'm taking ^_^:

let's let this set ={a,b,c} called set A and set {@,&,%} be called set B

so = {(a,@),(a,&),(a,%),(b,@),(b,&),(b,%),(c,@),(c,&),(c,%)...and the reversed order ^_^, I guess?
