## We Got A Problem #7: Drawin’ on the Multiplication Table

August 31, 2012 2 Comments

Draw a rectangle on top of the multiplication table. The numbers in opposite corners of the rectangle form pairs.

What can you say about the products of the two numbers in each pair? Explain.

What can you say about the *sums* of the two numbers in each pair? Explain. Ooh, that’s a good one.

See if you can find anything similar in the addition table. Or, drop a comment with your favorite pattern from either table.
