Email RE: Grading Natural Numbers

############

11:46 AM (1 hour ago)
to ######, Thomas, ######

Hi,

As I am grading all of the 243 homework for this semester, I noticed 0 is in the set of natural numbers according to this semester's MAT 243 book. I just want to confirm what your definition of a natural number is, since this book apparently uses 0 in this set. I personally don't agree with this, but I want you to let me know what I should do when grading. Some students assume this while others may be confused in the homework. Some students give functions that don't map to 0, but can be onto if 0 wasn't defined and so on. I know the "how to prove it book" did this to me as well... Just let me know how you think that I should grade this. Thank you and have a great day.

************************************

Hi #### (and ####### and #####), I tell them that the definition of the natural numbers is contested, they can assume the book's definition which includes zero, but if they want they use the definition that excludes zero they can as long as they specify precisely the definition they mean.  I expect that few people paid attention--and if they use or seem like they could be using the natural numbers excluding zero without so specifying, please feel free to knock off points.

best,

Tom

webwork question

Hello,
I am trying to do the division problems, and WW says the answer is wrong
for example, when it asks for 23/3, I input 7.6666, but they say the answer
is wrong.

*********************************************************************

Webwork is using the symbol "÷" to mean what the section 4.1 of the text book calls "div",  n÷m does not mean the quotient n/m, it means the number k in the unique expansion n=km+r where the remainder r satisfies 0≤r<m, i.e. n÷m  means the number of times m fits in n.  For example, 40÷3=13.

Homework Due February 28

Webwork section 3.2 and section 4.1

Bookwork sections 3.2 and 4.1.

Test Review Wednesday Night

Hi All, there will be a test review tomorrow night, here is the info:

Hello Professor Taylor,

I am informing you that there is a review session on Wednesday, February 19^th at 7PM for MAT 243. The location of the review is in Hayden L-60. The room is in the basement of Hayden Library; there should be an elevator just to the right of the Hayden Library entrance that should bring them to the bottom floor.  L-60 should be the room directly in front of them when they reach the lower level.  In order to have a productive review session, please tell them to bring their books, notes, and any specific questions they might have. The tutor scheduled for the review is John Jacobson (jrjacob1@asu.edu). Feel free to contact him if you have any suggestions for the review. Thank you and have a great day!

Sincerely,

question RE exam

Hi Professor Taylor

I have a few questions regarding the upcoming test. What all sections will be covered on the test this Friday? Are there any test reviews I can refer as I'm not sure what kind of questions will be there? Can I bring a cheat sheet to the test?

Thanks

******************************************

OK, to answer your questions in order.

1)We've covered seven sections from chapter 1, four sections from chapter 1 and one section from chapter 3, for a total of twelve sections.  Typically each section will have covered multiple topics--I haven't counted, and sometimes it's hard to tell if you've got two different topics or two examples of the same topic, but let's guess a total of 40 topics.  You are responsible for learning all of these topics. It would take much longer than the 50 minutes of the exam you were tested on all of these topics.  The test will instead be comprised of a selection of these topics. Any of the topics we've covered are fair game.

2) Here's a review session from last semester.  Same material.

3) OK. Let's say that you get one 3x5 card for notes, written by your hand. (Copied and 4x6 cards will be confiscated)

homework due Feb 21

Webwork section 2.3 and section 2.4.
Book homework sections 2.3 and 2.4.

OK.....I am told that webwork actually works on the web

Just to recap: this week's webwork is due Monday at 8:00AM, next week's webwork is due Friday at 9:00AM.

The due date...

Since there's still a problem with the webwork, and nobody is telling me that it is fixed, let's push the due date for this week's webwork back to Monday 8:00AM

Homework Due February 14

Webwork section 2.1 & section 2.2
Bookwork sections 1.7, 2.1 & 2.2

Webwork resolution, gradually by degree....

From the server admin:

****************************

Tom:

webwork2 has a new IP# and now things work again.

BUT it takes some time till all name servers flush and pick up the new IP#.

I hope that by tonight that's done.

The new IP# is 129.219.51.87

if you go to 129.219.51.87/webwork2

you can see your class and login as guest. 

But as soon as you login with your asurite id it will bring you back to webwork2 (the name and not the #)

So, we need to wait till the name servers are ready.

********************

Anyway, at the moment you need to know that the webwork is NOT due tomorrow.

webwork due date/time

The webwork due date/time has been extended by 24 hours

webwork problems

Today webwork has been behaving strangely and not well.  The server&network people have been working on the problem, but have not solved it so far.  I will reschedule the due date for your assignment, as soon as webwork will let me.
