    Thanks for the video, great explanation! More clear why we need an definition of a infinite cartesian product!

    isn't it (-2,2,3) a cartesian product of q×z×n ?
    Because -2 element of q ,2 element of z and 3 element of n

      We can say (-2, 2, 3) belongs to QxZxN. It also belongs to QxQxQ, ZxZxZ, QxZxZ, etc.

    Question
    Explain why the Cartesian product of 2 sets is an inefficient operation to perform.. Be very specific and use numbers.
    - This is a question giving to me in a assignment that i have to submit in 2 days from now. Could you help me with this challenge?
    Thanks

      It’s been a bit more than 2 days, but I have an answer.
      The function definition of an ordered pair relies on the first definition of an ordered pair, so by the time you use the function definition for ordered pair, you’ve already used another definition of an ordered pair, making the function definition unnecessary in this case.
