I must say i just found this sight through google and had to join because of this post. I am a math teacher and the correct answer is 2
48/2(9+3) is a different equation than 48/2 * (9+3)
using Pemdas or the correct order of operations in the first problem
we first add whats in the parentheses (9+3)= 12
second step we multiply 2(12) =24
final step 48/24 = 2
the people who are getting 288
are adding (9+3) =12
then they are skipping an order of operations and going straight to division 48/2 =24
24 * 12 = 288
I feel sorry for your students because you are teaching them incorrect things
No matter what you do you have to make an assumption as to what "/" means. Nobody over the age of 10 should be using that notation for this exact reason.
Therefore, assume that author wanted to use "_" but couldn't as this is a forum not suited to equation writing and work from there. I believe the logical conclusion is 288, but that is not the same as saying the answer is 288.
umm what the hell are you talking bout. / means divide plan and simple. No assumption are being made.
In higher level class you go dot see that - with dots above and below it in anything more than maybe text books and even then it is not that common.
Reason for it is the / is much clearer and less likely to be interpreted another operation (subtraction) by mistake. the / is very clear.
honestly I can not think of the last time I used something other than the / for division. I might of been in Jr high so close to 15 years ago. I know I sure as hell never used anything but the / in my upper level math class (cal and beyond)

As relevant as saying Apple sells more phones than Android does . . . oh wait, Android isn't a phone seller/manufacturer.
Well Apple doesn't sell its software for use on any other phones (or computers), so how is it competing with software-installed numbers on all hardware types? If people were shifting from Samsung or Motorola phones with Apple iOS to Samsung or Motorola phones with Android, than Apple would be losing in the software market.
This has always be a case of apples to broccoli (yeah, it's not even a fruit versus fruit comparison).

I can't see them making another architecture transition. The switch to intel was enough...
Why not? They've already done it twice - don't forget the 68K to PPC transition. I went through that too, and all I can say is: no, no, please, not again! I couldn't stand another transition.
CPU architecture transitions waste years of time, cost Apple and their customers huge amounts of money. The only way it's worth it is if the architecture you're going from is dead or dying, and the new one is much better, faster and cheaper. This was true for the 68K and sadly later for the PPC too, but there's no sign of the x86 losing it's edge in the price/performance stakes for laptops and above.
While it's not totally impossible that ARM might one day challenge Intel's x86 in the low-end notebook and el cheapo desktop space I can't see them ever seriously getting near Intel (or AMD) in the real desktop, server and serious MacBook Pro space. Intel's process lead, now a full generation and soon with 3D transistors too, will likely keep them ahead of any alternative architecture (barring perhaps a breakthrough in quantum computing or somesuch) for the foreseeable future. I can't see how Apple would gain anything real from moving away from x86 for the Mac. In fact, by 2013 the Atom may be seriously challenging ARM in the low-power performance stakes for tablets (and even possibly phones), so it might make more sense for iOS to transition to x86 rather than the reverse. Maybe.

It'll take me over 4 days.
Wow! What kind of slow-ass lines do you people in Australia have to suffer with?
Thats ridiculously slow. :(

Am I the only one hoping that Apple adds Firewire use to the iPods again?
I want firewire aswell usb 1 is far toooo slow. How my sposed to transfer films with USB, It will take all day.

Yeah :( all the seismologists had no idea an earthquake this big could be triggered by LiPo batteries.
Then there is the business plan / conspiracy theory that this was caused above the Sichuan epicenter by the Chinese reverse engineering of the American HAARP.

My 2-year contract finishes next month and my 3G is almost inoperative. No way I want to buy into the antenna problems with a 4. Glad you're happy though.Antennagate! Nice blast from the past ;)
Seriously though, I understand your hesitation. I did buy the thing and haven't had issues but plenty have, so its a toss-up. I'd just go for an Android unless you are really heavily invested in iOS apps. Last time I looked I was a few hundred $$ in on the appstore, since xmas 08. That's not so much that it would hurt to jump ship, but not so little that I'd make the decision lightly, either.

I guess I am the only one that remembers that it started out as a free service. Before it was .Mac it was called iTools and it was free. It was a benefit of being a part of the Mac community. It certainly was much more basic back then, but I have been using it since. The remote wipe for iPhone and other added features keep it worth the family pac price for this household even if it doesn't go back to being a free service.

Jeez, why do people think Apple will make the movie store/movie management part of iTunes? That would be the worst decision ever, the two mediums and two markets are so vastly different they need two seperate apps!
If Apple can just release an iTunes-like app combining Delicious Library style management with playback and the movie store, they've got a winner.
Bungle it in with the music store like they do with TV shows and keep the horrific video management in iTunes to manage them and a lot of people will be sick of it before long.
It could be simple as having two tabs..one for the music store and the other for the movie store.

I 3rd this.
Why not update them too? I understand that the MBP is PRO but still. What would the MB's be getting then as far as an update at some point?
If they continue to use Yonah, it differentiates the lines better and either allows Apple to reap a bigger profit as Yonah prices drop or they can pass that savings along to the consumer. (Or they can use the money saved on Yonah chips to up the standard RAM configuration to 1 GB...)

Wow, what a great job to completely and unfairly judge people.
I consider myself OCD level organized. One of the reasons why I am so organized (more so than ever now) is because much of my media and software have transitioned to digital.
You have a very negative spin on Apple's approach. Instead of "dumbing down", I'll call it "simplifying", and I absolutely welcome the change.
I to have OCD, but I also realize that's its not hard providing an option for people to burn a copy of their digital download to a cd or disk. So far, as we know, they wont be allowing that.
It doesn't make things harder, complicated or confusing providing such an option.

I think we will see the upgrade the Tuesday after they have enough supply to meet the demand. These laptops are selling great and they don't want to have to interrupt the supply. I think this is especially true at the stores.
Are they really selling that great??
Is there anyway to know??
I wonder how much people is waiting for the Merom MBP's.
I mean, in general like a couple o guys said here the ones available today are great. But I use Final Cut Pro ALOT, and I'm sure the 64bit will be VERY useful on that. So for me is worth the wait... as for alot of other Final Cut, Logic Pro, Aperture users...
I'm quite curious about those MBP sales... :rolleyes:

Well, in the supposed leaked 10.5 screenshots a month or two ago, people noticed that iCal and Address Book appeared to be merged into a single application.
Those were admittedly fake by the artist. They were never meant to be mistaken as real to begin with. People took it too far. (go figure)
umm....that magazine add looks rather real to me. WTF?:eek:
Except it uses the font that Apple stopped using like 4 years ago.
Anyway...It will be GSM... No Verizon or Sprint at all... the rest of the world uses GSM, and eventually Sprint and Verizon will give in... as the phone market (mostly made overseas where the networks are GSM) eventually stop bothering with those stupid CDMA companies that are disabling their sync capability anyway. I tried to buy a Sony Ericsson from Sprint a few years ago when all the GSM networks had them... Sprint didn't have a single bluetooth phone then. I dropped them for Cingular and the Sony Ericsson T637 so I don't know if Sprint does now or not.
I got on the ship less likely to eventually sink.

You have it easy. When I was a kid, in order to download a movie, we had to push two wheelbarrows full of blank paper six miles through the snow to the movie company's headquarters where we had to type the binary codes for the movie file out on a broken typewriter, cart it all home and retype it into the computer which would take 6-8 weeks during which we were allowed no sleep and no bathrooms breaks and only a plate of crusty, stale bread and a glass of filthy water. And when we were done, our dad would beat us around the head and the neck with a rusty railspike... if we were lucky.
(Sorry, couldn't resist carrying on with the Monty Python reference I saw starting up. :D )

If apple is looking for a way to fend off android then this may be part of the strategy. Mac.com is what makes my iThings work. If it was not for the sync OTA, then I very well may have been on another phone by now. Can't tell you how many times that it has saved me ass.
