math geeks

ok so i want to apprentice to be an electrician, but i suck at algebra. I goofed off in class and barely got it done, so can anyone recomend any books learning the type of problems shown here?

just buy yourself a TI89 and learn how to use it.

Most of the Math/Science sections of bookstores--and libraries, for that matter--have workbooks on pretty much all levels of math. Good luck!

in middle school and high school i was hoorrible at math, but in the real world and college it is easy because i can actually use it for something usefull.

im going to calculate the wavelength for a quarter wave dipole and matching network for a yagi beam antenna now

yay for math in the real world

I just had a window repair guy round at my place, and he was musing on how he never thought he'd need to know stuff like Pythagorus' theorem until he got into working on balustrades and things.

Funny how we end up wishing we'd listened to our teachers more!

ahem...that's a yag beam mister. yttrium-arsenic-gallium laser

if u want my opinion, i learn math much better from a teacher than by a book. i mean, if u get stuck in a book, ur fucked w/o a teacher.

i suggest you hookup with a community college algebra course if ur serious about this.

check out http://sparknotes.com as you may find some of the things there useful for you.

Oh yeah...don't hesitate to ask if you have troubles...there's lots of math geeks round here.

mmmmmmm....math. it was always my best subject.

go back in time for a moment and get one of those SAT workbooks not just with practice tests, but the ones that have explanations with the answers. And feel free to ask.

OH NO, i'm such a dork, I just did those sample problems for fun...

ahem, no, since he was talking about a directional antenna it IS a yagi.

okay am i just being really dense, coz i and all those around me reckon question one is 16, but that isn't one of the possible answers...

help.

Looks like you were doing the problem from left-to-right, but the order is:
Parentheses first
then muliplication & division (left-to-right)
then addition & subtraction (left-to-right)

So:
A = 5 + 3 (4 - 2)
A = 5 + 3 (2) {simplifying the parentheses first)
A = 5 + 6 {multiplication}
A = 11 {addition}

cheers

I daresay there's enough interest here to petition for a new group... Lord knows there's enough math geeks here (myself included).

I just wanted to take this opportunity to announce that I'm about to drop $110 on a TI86 for my algebra class. That hurts. I hate algebra. I am not a math geek. Math geeks are hot, but math is not. That is all. Thanks for your time and attention.

I was wondering when you'd show up.

I did. *hides slide rule*

Al said:
Don't. Graphic calculators are a waste of money and actually slow down the learning process. Also, there's no way in hell you could ever even think you needed one in an algebra class.

Thank you and good night.

Too late, Al. My algebra teacher told us we had to have one. We *are* doing graphing, but I'm perfectly comfortable doing it the old-fashioned way. But this teacher wants us to learn to do it on the calculator. Plus, at the campus bookstore they told me the TI86 is being phased out, and the TI89 is the one to get if you plan on going further than introductory algebra (which I am, but just regular college algebra, no calculus please!). So I'm now out $150 instead of $110. Dammit, I could get a good tattoo for that. I appreciate the advice though, Al.
