For those who forgot Cartesian product
The Cartesian product is a mathematical operation that combines elements from two sets to create a new set. It is represented by the symbol "×".
To find the Cartesian product of two sets, you pair each element from the first set with every element from the second set. The result is a set of all possible ordered pairs.
For example, let's say we have two sets: A = {1, 2} and B = {a, b}. The Cartesian product of A and B is:
A × B = {(1, a), (1, b), (2, a), (2, b)}
Each ordered pair represents a combination of an element from set A with an element from set B. The Cartesian product allows us to explore all possible combinations between two sets.
😊

Thanks a lot
