The Cartesian product A x B is the set of ordered pairs where the first term is in A and the second term is in B.

For part a, (1,c) is one of the elements in AxB

It wants you to list all of the elements.

[drifting hare]

thank you

its asking if its a bijection or not

99% sure its no bc the cardinality is different but also idk what it wants me to do

[drifting hare]

how do i know the cardinality of order pairs

also no clue what A/B means

[magic knoll]

Try writing out AxB and count how many elements are in it.

[drifting hare]

1 order pair is 1 element?

[magic knoll]

A\B means the elements of A minus whatever elements are in B

[drifting hare]

are the first two right
