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)

Powerful system for sure but looking at this thing it seems the base unit is a workstation to me. The 7300 GPU is a $99 Gpu so I was surprised they went so low with the base graphics.
I think there are many people who need all the CPU power they can get, and don't need that much graphics power at all.

I am not sure why the increasing erosion of the middle class and income discrepancy between the haves, and have nots, isn't realized as a major security problem in the US. The working middle class and poor can only be pushed around so much until somebody is going to get pissed off. A socialist/populist revolt ala Egypt is not inconceivable.

im pretty sure thats what steevie boy has in mind ;)
I never buy "locked" phones anymore. Yeah, unlocked ones cost more because they're not subsidized by the cell phone companies, but if service sucks or I go overseas (which I frequently do), I can get another company's SIM and put it in my phone. Voila! It works!
I have a Sony/Ericsson W810i with 2GB memory card. Its tiny screen only allows 176x144 video (MPEG-4 or 3GP at 30 frames per second), but that also becomes an advantage. Full-length movies at that screen resolution only take up 150-200MB. I use FFMpegX to compress movies for my phone.
The phone also has a 2 megapixel camera with true autofocus and macro, and plays MP3 and AAC/MP4 audio files with its built-in speaker or outstanding earphones. It has a FM radio with RDS, plays Java games, has Bluetooth and can be used as a Bluetooth controller/mouse or modem on Macs and PCs, it supports EDGE high-speed Internet, it can run the Java version of Opera but it also has a decent built-in browser, and is fully supported by iSync. And it's tiny.
Okay, Apple... that's your yardstick. Come up with somethings significantly better. I know you can do it.

...only if the Macbooks also get a price drop, because the Core Duo chips should get a price drop, if Intel even keeps making them.
What everyone keeps forgetting in this discussion, however, is that the Core2 Duo chips will be considerably more energy efficient, reducing heat production and prolonging battery life. Considering that they will be introduced at the same price as the current Core Duo chips, why not use them in the Macbook, at the 2 GHz speed?
Furthermore, transitioning all Macs to 64 bit chips as quickly as possible would also hasten the transition to a true 64 bit system, as developers would have more reason to develop for a 64 bit environment (assuming that OS X 10.5 is truly 64 bit).I'm with you MacInDoc. Intel is not going to keep selling Yonah for long before they stop making them. Anyone who does the least amount of research should see that Merom is a much better way to go for all the reasons you mention. If Apple is really trying to stay state-of-the-art, they will lose Yonah as soon as Intel's supply can keep up with Apple's production volume. On the MacBook front, this should be able to happen by October-November, I imagine.
If Apple doesn't put Core 2 Duo in MacBooks @ 1.83 & 2GHz by November, the competition on the PC front is going to make Apple look like they are selling outdated products as if they are current. This will not fly among savy buyers and MacBook sales might falter - perhaps even tank without such a switch. :eek:
Almost all mobile computers selling for more than $1k by November will be Core 2 Duo. So for the holiday shopping season, Apple has got to put them inside MacBooks by then.

Vote for "Undecidable because of the rubbish typography".
Exactly.
To avoid the 'implied' multiplication, it should be shown as below.
The answer is then obviously "2".

I don't understand people's expectation for an iPhone 5 in 2011. I bet Apple didn't make as much profit fitting in the retina display, 5MP camera and putting together that design compared to the 3G. Why dump a year old design? It would be uncharacteristic for Apple to kill it. I love the design and I'm sure it will stand the test of time.
Maybe an announcement of a 4S maybe with A5 chip etc on the side as a surprise? That'll cover the iPhone 4 White rumors and give Apple a chance to improve the antenna.

At the very least, Apple is making my summers seem very very slow, and that I can't complain about.

How so?
The current method is "the OS DVD you buy can be used anywhere, as often as you like, forever."
How could it be worse than that?
The licence is only for one computer.
If you want to install it on a different machine you must uninstall the original copy first.
The Mac App Store says:
"You can install apps on every Mac you use and even download them again."
That implies that if I go on a friend's computer for 5 minutes once a year I could install Lion on it for no charge.

Why is everyone freaking out about re-installing the OS? Lion creates a recovery partition as part of the install process. If you need to reinstall, just reboot and hold down option...pick the recovery partition and voila.

We�ve never had a game like this before, so you shouldn�t let this put you off.
if we explore is that our move and then the villain makes his? Or if we pick a door would this be a way to avoid the villain�s traps, since he may have put one in the room we�re in?
There's a few mis-stated rules in Don't panic's rules that I will address shortly.
But one is that a trap activates as soon as you attempt to leave the room. The only way to avoid a trap is to explore the room, which will discover, and disarm, the trap.
With that said, there are currently nothing placed on the map by the villain. He will make his first move after you slow-pokes are done ;)

My 3GS is working just fine -- I'm more than content to wait for a real refresh to the iPhone (not some garbage update that keeps the same flawed form factor re: antenna and use of a shattering glass back).
Most people claiming they'll switch won't -- rebuying your Apps for the Android marketplace represents a non-insubstantial hidden cost to switching for many people.

If I could just have a Mac tablet that I could type and write notes on for class, I'd be in heaven :)
I used this (http://www.samsclub.com/shopping/navigate.do?dest=5&item=143780) in class to write my notes on. Very durable (I dropped it once and was still able to use it!), and I haven't had a problem with it crapping out on me when I needed it. Storage space is limited but I would buy another one in a heartbeat.
