I'm looking forward to your book.<br /><br />I also wanted to let you know that in about 15 minutes there will be a Trinomial Factoring Proof animated video on my site. I was inspired by a Professor jack Rotman's simple explanation of why we multiply AC to fond the factors that should add to B in a trinomial. Good stuff. I hope you like my video! It'll be on my blog (http://zerosumruler.wordpress.com/) right after it finished uploading onto YouTube (http://www.youtube.com/user/ZeroSumRuler)<br /><br />Thank you for the suggestion to make a video proof. I'm excited for people to see it (and comment or complain!)ZeroSum Rulerhttps://www.blogger.com/profile/01294425340189840174noreply@blogger.comtag:blogger.com,1999:blog-5303307482158922565.post-63517785181318724072010-06-21T12:33:01.873-07:002010-06-21T12:33:01.873-07:00Very tempting this is...

Ask volunteer 2 to write down some other integer which has all the digits of the first number rearranged in some order. Ask volunteer 3 to verify that volunteer 2 did his/her job correctly and then give him/her a calculator to compute the difference between the two numbers and write it down. (this difference is a multiple of 9, which can be shown through modular arithmetic)<br /><br />Now you claim that you can tell them the last digit of the difference if they tell you the rest of the digits of the difference. For 8 of 9 cases, this isn't a problem. When the rest of the digits also add up to a multiple of 9, the last digit can be 0 or 9. Under such situations, it is advisable to steal a trick (sorry, illusion) from Gob (of Arrested Development). Hide a playing card with the number 9 in a shirt pocket and guess 0. If it fails, pull out the card as some sort of dramatic apology.Haohttps://www.blogger.com/profile/02348974241652264510noreply@blogger.com
