Example 1
Let A={John,Jim,Dave} and B={Mary,Lucy}. Determine A×B and B×A.
- Answer:
-
We find A×B={(John,Mary),(John,Lucy),(Jim,Mary),(Jim,Lucy),(Dave,Mary),(Dave,Lucy)},B×A={(Mary,John),(Mary,Jim),(Mary,Dave),(Lucy,John),(Lucy,Jim),(Lucy,Dave)}. In general, A×B≠B×A.
Solution
We find A×B={(John,Mary),(John,Lucy),(Jim,Mary),(Jim,Lucy),(Dave,Mary),(Dave,Lucy)},B×A={(Mary,John),(Mary,Jim),(Mary,Dave),(Lucy,John),(Lucy,Jim),(Lucy,Dave)}. In general, A×B≠B×A.
