An ordered pair is of the form (x, y) where x is the first term and y is the second or terminal term of a set of elements A and B
Ex: write the order pairs from the sets
A = {x:x is even number less than 10} B = {x:x is a factor of Y}
Solution:
A = {0, 2, 4, 6, 8} B = {1, 3, 9}
Ordered pairs (0,1), (2, 3), (2, 1), etc…
