Math Dude sampleCategory @Allan: Thanks for the comment and for checking out the show! Yes, you're not the first person to take issue with my inclusion of zero in the set of natural numbers -- I talked about this a bit in episode #7. Feedback is always welcome, so please don't hesitate to let me know what you think! http://mathdude.quickanddirtytips.com/what-do-prefixes-mean-in-math-part-1.aspx?commentid=33924#Comments http://mathdude.quickanddirtytips.com/what-do-prefixes-mean-in-math-part-1.aspx?commentid=33924#Comments Wed, 13 Oct 2010 16:13:36 GMT allan sampleCategory As a 35 year high school math teacher, I just heard about your podcasts and started listening from the first show. I like your explanations especially about number lines (I am up to about show 6). I must take just a bit of issue: zero is a whole number not a natural number. You also mentioned negative whole numbers: actually the negative integers are the negative (my students liked "opposite" for negative) of whole numbers. I also heard you mention the farther to the left on a number line would be "larger" (once). I know I am just a picky teacher. Teachers have to always teach!!!
