**September, 1999**

BACK TO CONTENTSDate: Fri, 22 Oct 1999 09:19:00 -0400 (EDT) From: Stacey Bearden stacey@mathforum.org To: All Dr. Math Doctors Subject: Dr. Math in September =-=-=-=-=-=-=-=-=-=-=-=-=-= Ask Dr. Math Newsletter September, 1999 =-=-=-=-=-=-=-=-=-=-=-=-=-= Greetings, docs! Usually here is where I welcome you to the new month, but since we're already pretty far along, I think I'll skip that. But where I live, all the trees are turning beautiful colors, so I welcome you to that, if you live in an area where that happens. We apologize for the server problems we've been having. Unfortunately, they caused me some difficulty in getting into triage, which is why the newsletter is late. But when I _did_ get through, imagine what I found... *************************** 8847 -- incoming questions 2223 -- answered questions 25.1 -- percent answered *************************** Wow! At the end of last school year, I was excited to report that we'd received 6000 questions in one month. But now we're up to just about 9000. That's a huge increase - can anyone do the math :-) ? If you count all the bad-address questions we have to delete, we're way over 9000 incoming questions per month now. Now seems a good time to welcome our new docs for September; maybe they can help with this tremendous load! Say hello to... Dr. Shelly Dr. Sandi Dr. Lk Dr. Aileen Also, congratulations to our newly tenured doc: Dr. Lilla And I must apologize; I forgot to include an August tenure in last month's newsletter. A big congratulations to Dr. Jesse AND NOW, THE ARCHIVE NEWS: ===============+++++=========+=========+++++=============== NEW FAQ: How do you round a number to the nearest tenth (10th), hundredth (100th), thousandth (1000th), etc.? See "Rounding Numbers" in the Dr. Math FAQ: http://mathforum.org/dr.math/faq/faq.rounding.html +++++====+====+++++ And the ARCHIVING STATS: More than 125 new question-and-answer entries were added to the tables of contents during September of 1999. ===============+++++=========+=========+++++=============== NOW THE NEWS NEWS: Some of you may recall a blurb from a past newsletter about a journalist wanting to speak with some math docs. Well, some docs spoke with her, as did I, and she wrote a lovely article. Dr. Math is one of two services featured in this article for The Guide to Math & Science Reform, and she details us quite well. Take a look - you'll find some great quotes from your fellow docs. In addition, a journalist from the San Francisco Chronicle interviewed me about our service for an article about online homework help. Dr. Math certainly isn't featured quite as much, but we do come off quite well. ===============+++++=========+=========+++++=============== And now... Tip of the Month! ================================= September's Tip: Be careful not to do the students' homework for them! It can be tempting to answer the question the student asks, but be sure not to detail the steps and answer of the student's problem. You can be creative in your techniques, but here are a few suggestions: you could do a similar example, give some hints, help them set up the problems, point them to an archive category or URL, etc. Stay tuned for more on this topic. ================================= And now THE THANK YOU SECTION: Every month there are a couple of notes that I can't identify. This month there were several, perhaps due to server problems, so I've decided to include them here. I've included the subject, date, and email address, so maybe you can identify it as yours. ===============+++++=========+=========+++++=============== base5 Thank you - now I understand base 5. ================================= THANKS Just to say thanks for all the help. Junior - Simpson College, IA. ================================= Quadratic Equations Thanks for your help! Now I can finish my math homework. ================================= JUST THANKING YOU I just want to thank you. I was having problems at work and I forgot how to subtract mixed fractions and you really helped me. This was my problem: 10 11/16 - 8 3/4 = 1 15/16. I work in the printing office and it is important that I measure materials accurately or else the job can come out awful. I can't have that. Thanks again! ================================= Fibinotchy Thanks for your response! Yes I believe that's what she is looking for. Would have helped if my daughter had the right spelling. - Cathy ================================= thanx! Thanx for helping me through this time of exams! I really got good marks, and I feel that I have improved, in all my subjects not just maths. Thanx a lot! PEACE OUT, ROBYNN [CAPE TOWN, SOUTH AFRICA] ================================= Converting an angle to radians.... Thank you very much. Precisly what I needed :) - Jason ================================= Thanks for the Specialized Math Help Thanks for the Help. ================================= Word Problem Thank you very much for answering my question. The solution I got was 30 note cards and 5 greeting cards, but my approach was quite different (and probably more exasperating) than yours. I appreciate the lesson! Sincerely, Karen ================================= Solving Exponential Equations Hi, sorry for the confusion in the symbol, what I meant for it to be was a division sign, and somehow I made it a percent sign. Anyway, thanks for your help. ===============+++++=========+=========+++++=============== For all those that I _could_ identify, I'll be sending them along to each recipient soon. Watch your inboxes! Until next time, Dr. Stacey Doctor Math Administrator The Math Forum
