PEMDAS... First time ever that I hear of it.
I did no go to school in the US.
So.. if the priorities are Parenthesis, then Exponents, Multiplication, Division, Addition and lastly Substraction, using your rule:
48/2(9+3)
First whatever is inside the Parenthesis: 9+3=12
48/2(12)
Then Exponent: none
Then Multiplication: 2(12) = 24
Then Division: 48/24 = 2
There you go...PEMDAS fans.
No. That's not how it works. Once you get to multiplication/division, you go left to right. It's 288. And for those of you who get 2 by using calculators, any math teacher will tell you that calculators always get the rules of operations wrong. That's why we teach kids pemdas so they know what math to do first and they can use the calculators to help them do the parts of the equation they need help with.
Precisely
The answer is 2, not 288 (it can't be that)
Following PEMDAS (Parenthesis, Exponents, Multiplication, Division, Addition, Subtraction):
9+3=12
12*2=24
48/24=2
2 is the final answer.
As I stated above, you are missing an Important rule of pemdas. When you get to multiplication/division or addition/subtraction, you go left to right. So: 48/2 is 24. And 24 *12 is 288. If u don't believe me, just google pemdas and u get the rules:
http://www.mathsisfun.com/operation-order-pemdas.html
Mac'nCheese: I think that in elementary school you first learn to multiply and then to divide. So first you multiply and then you divide.
That left to right rule is not following the order of the letters.
So for this case it is not PEMDAS but PEDMAS...
The Arabs give us the numbers that we use nowadays, and they do write from right to left.
So your math teacher is telling us that Mac OS X is giving us a wrong answer...You might need to watch waiting for Superman.
MacnCheese is correct
PEMDAS is more like this. PEMDAS isn't really an accurate name, but it helps remember the basic order.
1) Parenthesis
2) Exponents
3) Multiplication or division ... going from left to right
4) addition or subtraction ... going from left to right.
48/2(9+3)
=48/2(12) or 48/2 * 12
(by parenthesis)
No exponents
No addition or subtraction
=24(12)
(by multiplication or division from left to right)
=288
(by multiplication or division from left to right ... again)
288 is the answer. There is no way you can get 2 by following the order of operations.
And people should know better than putting a whole equation into a calculator and depending on that answer ... (spotlight, google, calculator)

Come on - there will be an iPhone 5 in July. That's the customer expectation and if they did NOT release it then, their stock price would suffer and they would certainly lose market share to the newer phones. They are already somewhat behind newer phones that have much larger screens, faster processors, better cameras, etc - no way they wait until next year or even winter 2011. They will find component supplies and keep on track.

Why can't you just download it and back it up on a USB key, or a thousand USB keys?
Give me one good reason why you can't do that. If you're posting on Macrumors you have enough bandwidth to get it, just may have to wait a few minutes.

I'm not impressed if this is where the iMac display is potentially going , the current GPUs can barely drive the resolutions they have now in anything other than simple desktop apps . , can you imagine what video card you would need to drive a game (say portal 2 which has low to modest requirements) at 30fps + on a screen with 3200 or higher resloution ? Well whatever that GPU is , apple will ship with the one released 2 years ago and half the RAM it shipped with on the PC .
I love the mac OS , I love the mac design , I hate the "last years tech with a shiney shell" we seem to have to put up with , super high res screens and faster I/O ports are all well and good , but put a decent GPU in now the mac is becoming a contender as a home gaming platform .
Think I ranted a bit then , sorry :rolleyes:
Nightarchaon, youre my hero. All the conjecture about future hi res displays aside...the current iMac is almost crippled with its current GPU options. At 2560x1440...it should have something equivalent to an HD 6950/GTX 570. Given that those cards would blow past any thermal limits Apple has set...iMac owners are in a bit of a graphical quandary. It's an utterly gorgeous machine, superb display, great CPU, decent RAM, sufficient HDD options. But those graphics? :eek: SP cores and clock rates aside...it should have 2GB of VRAM(frame buffer) at that res.

Wish Apple did something towards resolution independence and not make images bigger and bigger. :confused:
Resolution independence will not stop images from getting bigger. Unless you are dealing with vector art, scaling an image up will decrease quality. Resolution independence will be a function of taking the biggest image that might be used and scaling it down.
Even with vector art, you lose some image quality with scaling. You can't create new detail.

You think you've got it bad? In Britain we have
milk and beer by the pint
coke by the litre
roads by the mile
tablecloths/fabric etc by the metre
petrol/diesel by the litre
fuel efficiency is measured in miles per gallon but carbon emissions are measured in grams per kilometer.
weight of people in stones and pounds
sugar/flour etc in kilograms
fruit by the pound
cheese by grams
bread loaves are labelled in grams, bread rolls sold by the dozen.
height in feet and inches.
and so on. It's a real mess. Basically we started to change, then stopped because people didn't like it. Then the EU decided certain things must be measured imperial, so now we have a have way house where nothing makes sense.
We switched from pricing petrol in gallons to litres when petrol got to 99.9 pence per gallon, and it was easier to change the signs to litres than add another digit. :rolleyes:
I grew up in Greece using only SI so it was very strange for me to measure weight in stones as I haven't heard it before. Luckily everyone in Scotland also knew their weight in kilos too.
My biggest problem was that distances where in miles and therefore everything was way further that I though. It's just an inconvenience but after a while you get used to it.

OK. So we all agree 100% that the USA should switch to the metric system. Now the question is how? Cold turkey, change everything at once, all new signs on roads, all new packaging on goods, etc. Little by little, make new signs have both miles and kms and keep that for a generation? What would be easier?

One of the main bonuses of a paid service is that it limits the number of users so they can get an email such as joe.blogs@me.com. When services become free, more people sign up until people have to settle for Joe.M.blogs5739@me.com, and then the service looses its upper-market feel.

i thought the merom chips have the same pricing as the yonah 5 or 6 month ago. that would mean apple could switch to all merom (MB, mini, MBP). especially since they are compared to dell & co. in the windows world you are almost forced to use the better chip (merom) because the competition is fierce.Merom is launching with Yonah's original pricing. Yonah is going to get another price drop later this year.

Thanks for the links.
I don�t see why a 20% increase in speed is going to rock the boat. Especially if it�s in the MBP. So if it is ready for shipment I don�t see any advantage in waiting for the MBP line to upgrade.
I guess I�ll have to do some research about the battery performance.
Noone knows what Steve Jobs will do, but I think he had been roper-doping long enough with the G3 and G4. What 6 years with the same G4? He needs to come out swinging while Apple still has a strong brand name from the iPod.
I hope to see some changes. The last 5 years have been so slow that it hasn�t been worth keeping up with.
At the same clock rates, the battery life for Yonah and Merom are the same, just a boost in computational performance (and slightly less heat, I think?).

What makes a product "Best" in its category is defined by different people differently. For some people "best" is a free phone because they can't afford anything else. Some people pour over the specs and select the "best".
For me, "best" is the phone that operates the most intuitively to my way of thinking. I want something that I don't need to refer back to the manual to use its features. My Android Incredible came with a 8" x 11", 73 page manual that I need to use to operate the phone... that fact speaks volumes to what separates the Android from the "best."
did you need to use that manual to help operate the phone?
honestly I think android is just as intuitive and easy to use as ios. I can't believe people actually say they don't understand how to use android. for god sakes my 8 year old nephew figured out his dad's android phone after a 30 minutes of playing with it.
I prefer ios for it's elegance but android isn't tough to use at all...

If mac users don't use av software, there's little motivation for anyone to supply it. If NO ONE is working on av software, then in the eventuality that we do need it, we're all starting from scratch. That's just never a good place to be if you can with minimal effort prevent it.
It's kind of like getting your flu shot in a year when the flu isn't supposed to be particularly bad. I seldom get the flu, but I go ahead and get the shot every year anyway because if no one does, there's little motivation for pharma companies to develop future flu shots. Which means in the really bad flu years, there's a shortage because only one company is making the shot.
Flu vaccines are very much like AV software for Mac. They both rely on fear, uncertainty, and doubt. H1N1 killed fewer people per year than the more typical strain of flu but the marketing hype made big business a lot of money.

That issue could have been largely solved if they had just faced a standard high end GPU with the intake facing towards the back and the exhaust on the side. But Apple is too vain to put a vent on the rear of the iMac to accomodate the intake of a high quality GPU, let alone a slim exhaust vent on the side.
If they had simply used a standard GPU like that it would have opened up quality gaming on the Mac and made it simple to upgrade to newer cards so that people didn't have to chuck the entire computer every time they wanted a new video card.
I'm sure you are right.
Given a bit of good design work on Apples part, when I say good design I mean, technically good as opposed to artistically good.
And in conjunction with Nvidea/ATI (personally I still like Nvidea as they seem more on the ball with Tessalation and Cuda programming for offloading CPU work onto the GPU)
A "Spread out" design, given the large rear metal surface are of an iMac and a few very neat vents to pull in cool air using a slow well designed fan, from the side or bottom and exhausting the warm air on the other side/top could be well within technical possibilities. And would address the weak spot Apple have had for a decade or two.
But, as has been said, Apple seem to fear this market as they seem to think they can't compete, and if you know you can't compete it's best not to enter the race. They want to go for poorer quality graphics, or we can use the term that sounds better than that.
The casual gamer.
Quite why this Apple created concept to cover their weak point should be happy with less quality/detail is unsure to me.
It's like saying people what watch films all the time and enjoy them should have the best picture quality we can deliver.
However, those who just watch the occasional movie should be happier with a lower quality image.
Kind of a strange concept when you think about it. and really we should all accept it's just a created excuse to excuse away a weak area as I said.
But, as you quite rightly said. Apple are too vein to spoil, in their mind the cosmetic look of an iMac by adding in cooling slits to allow for higher end graphics cards.
A shame really as if they had taken graphics a lot more seriously 15 or 20 years ago, they could be kings of this sector now.

No.. They make mobile processors. Low power usage.
If you read the article again, it ays the rumor is for laptops. Very doubtful apple will move the desktop line to an ARM processor as there is nothing that competes with the current tech.
For laptops (specifically the air), the move may make sense. I don't see apple moving the whole macbook pro line to ARM. maybe the airs and the regular macbooks.
It still wouldn't be worth the software fragmentation that would take place. Plus, Intel has continued to make their possessors more power efficient.

No, they come out with new phones every WEEK, and you actually mean "cheaper and ********". This is not coming from a fanboy, I own and use daily an android device.
I would very highly doubt if they actually delayed the release. Techcrunch doesn't have an amazing track record, if I remember right.
True, they got tons of them comming out.
They might be cheaper but some of them do have better hardware specs but when it comes to the OS and the way it runs everything they sure are crappy and cant compete with the iOS.
I'm going to laugh at all those who say iOS 5 wont be delayed when it actually will be :rolleyes:
I give it by July there will be a new ios out and a new iphone.
Just my guess judging by the last 4 years but we will see how it goes.
Nobody really knows.

iCal has been visually overhauled to look like the iPad version
Just clarifying, iCal for iPad looks like paper sitting on top of a cardboard/cork texture. This is a leather book... so maybe we'll see an iPad UI update as well?
