Guest Posted October 11, 2000 Report Share Posted October 11, 2000 This has absolutely nothing to do with Armenians, but what the heck, we need a change of pace once in a while. Here is a way you can multiply any two digit number by 11: Example: 23 x 11 Change the 2 to the hundreds place, leave the 3 where it is and leave a blank space for the tens place 2_3 Now add the two digits 2 + 3=5 And place the sum in the tens column 253 This is your answer to 23 x 11!

Guest Posted October 11, 2000 Report Share Posted October 11, 2000 My first immediate reaction when I saw this was, "Oh No! I've had just about enough of mathematics to last a lifetime! (We have to do lots of it in the course I'm in, you see), No more! But I'll do a bit to humour him" But when I saw it it looked funny and intersting! Let me try it....12 * 11 1-2 1+2=3 123 12*11=123 How'd you find that one out? Quote Link to comment Share on other sites More sharing options...
Guest Posted October 12, 2000 Report Share Posted October 12, 2000 Im a sixth grade teacher, and am constantly trying to find things to spark my students' interest. I learned this at a Math In-service. There is also a neat way you can multiply with any digits using squares that you draw on your paper. I wish I could show how! Also you can multiply any number by 9 by simply adding 0 to the number then subtract the number you want to multiply by 9. Like this 78x 9 780-78702 Of course this takes longer, but its neat to show that there are different ways to solve problems. Quote Link to comment Share on other sites More sharing options...
Guest Posted October 12, 2000 Report Share Posted October 12, 2000 I don't mean to pipe in on every friggin' thread here but....math is my profession. I have a bachelors in math/statistics. I'm an actuary; we are the numbers guys/gals for the insurance industry. Feel free to flame me if your auto rates have gone up lately. Kazza, if you have any specific questions, I love tutoring. Just hope I can answer 'em... [This message has been edited by Pilafhead (edited October 11, 2000).] Quote Link to comment Share on other sites More sharing options...
Guest Posted October 12, 2000 Report Share Posted October 12, 2000 Teachers? (not the whisky) I just love that other problem you did! I shall need to try that, seriously now, because I struggle a LOT woth my multiplication tables ESPECIALLY 9's, and the basics. I am completley apush at it. The advanced theory stuff I'm good at, with a calculator! But I could be better because the not knowing basics slow me down. I didnt vochinch hard enough at baby school. Because I am doing computer science, programming, and natural sciences, inevitably that involves maths. So pilaf head, you have literally saved my life bro Farsi Jan, what is an in-service?

Guest Posted October 12, 2000 Report Share Posted October 12, 2000 My father taught me that trick of yours when I was much younger and I still remember it!! lol...I just wish I retained everything my father taught me and still teaches me, I think I'd be much better off. Steve, I think it's adorable you teach six grade. I work with kids myself (in special ed.) and it's not everyday you come across a teacher who happens to be a man, so the mere mention of a male teacher makes me melt. I don't know if you plan to make a career out of it, I hope you do Gayane Quote Link to comment Share on other sites More sharing options...
Guest Posted October 12, 2000 Report Share Posted October 12, 2000 Gayanne babe, That's a coincidence! I want to work in teahing myself, but teaching special ed. I think that's already his career. At my old school there were plenty of male teachers, but i dont know if times have changed now. Anyway. Keep all the fun posts coming! P.; where is Artur lately? I havent seen him round here. Maybye he's gone on too many feminist marches. Laters Quote Link to comment Share on other sites More sharing options...
Guest Posted October 13, 2000 Report Share Posted October 13, 2000 Kazza, an inservice is a workshop/class offered to teachers to help them develop better professionally. Gayane, wow, thanks! I love teaching and kind of fell into it. I plan on continue teaching for a long time. Quote Link to comment Share on other sites More sharing options...
