Evens and Odds in the Multiplication TableDate: 09/11/2005 at 09:24:44 From: Lala Subject: multiplication tables Dear Dr. Math - in the multiplication table, is there the same number of even numbers as odd numbers, or is there more of one kind than the other? Can you explain why? Date: 09/11/2005 at 10:44:25 From: Doctor Ian Subject: Re: multiplication tables Hi Lala, Let's make a small multiplication table, but instead of using actual numbers, we'll just use "e" for even numbers and "o" for odd: x o e o e o oo oe oo oe e eo ee eo ee o oo oe oo oe e eo ee eo ee In this table, "ee" means "an even times an even", and so on. By looking at the table, can you see how to answer your question? Note that the product of an even number and any other number will always be even. - Doctor Ian, The Math Forum http://mathforum.org/dr.math/ |
