Title: MATH COMPETENCY TEST
Post by: [REDACTED] on November 01, 2008, 07:27:16 PM
There are two different positive three-digit integers that are exactly forty-eight times the sum of their digits.  Find both three-digit positive integers that satisfy this condition.
Solve for possible luts.

Honestly, it isn't that bad. You just have to use the first and second derivative tests. baddood;
Also, use sign graphs if you are srs confuzzled.

That's why you'd be a terrible math tutor. You'd keep teaching him interesting stuff that was completely irrelevant to what he was actually supposed to be learning.

This is why my sister no longer asks me for math help.

I appreciate your honesty. I'd problably try to re-establish the link between i and the roots of unity, and then start exploring the Euler Identity. I DID tutor a kid once, but we just swore and I showed him how to do a few problems since he had a home tutor anyway.

I was mostly joking, but I do find that people who are actually interested in math tend not to work well with people who just want to pass the course. It's true for other subjects as well.

do my problem set for me wariodood;

How many numbers are there between 400 and 730 where each digit is 1,3,4,5,8, or 9 under each of the following conditions:

1) No futher restrictions
2) The number must be odd
3) No digit is repeated
4) Both 2 and 3

But isn't a teacher who loves a subject the best candidate to put that love in his or her students?

Yet, tutors are both peers and they contain less formality as instructors than teachers, so you're less likely to gain something amazing from them. Then again, they can express ideas in ways that a teacher can't which may appeal more to a student, thus making them start to love math.

Permutations, yum. Let's mess with this.

For someone who's actually interested in learning, a teacher or tutor who loves the subject is great. In my experience, though, a lot of the people who need tutoring are the ones who really don't care about the knowledge they're gaining and just want to get their course credit and get out. If you manage to make them to enjoy the subject then that's great, but often they've decided long before that they're never going to like math or be good at it and its pretty much impossible to change their minds.
