Question

What is f×e where e={1,2,13} and f={44,8,2}?

Answer 1

`f* e=\{(1,44),(1,8),(1,2),(2,44),(2,8),(2,2),(13,44),(13,8),(13,2)\}`

Explanation:

The Cartesian Product of two sets is all pairs in which the first element of each pair comes from the first set, and the second element comes from the second set.

`f* e=\{(1,44),(1,8),(1,2),(2,44),(2,8),(2,2),(13,44),(13,8),(13,2)\}`

This was built using 1 from the first set paired with each number in the second set, then using 2 from the first set paired with each number in the second set, then 13 from the first set paired with each number in the second set.
