The answer is 1
why are people saying its 41? I dont even get that?
Once you his the x0 it all goes to 0, then add the 1
so its 1Comment

It's obvious that you're an intelligent guy and have been very successful. I've personally paid a lot of attention to many of your posts over the years. That being said, I think you're simply mistaken in this case, most probably a slip of the memory due to the time involved.
The order of operations were the same 25 years ago as they are today. They applied when I learned them in grade school 25 years ago, and when I studied Computer Sciences in college 15 years ago. It's a fundamental principle essential to keep Mathematical equations from being ambigious.

41, some people must be dumb.
By the way do you remember similar thread with different equation months ago? At least there were some thought into it (because of the implied brackets). While this equation even do not raise any question..Comment

I'm not suggesting that the order of operations didn't exist 30 years ago. As new engineers we were all made aware of it. What I am saying is that it wasn't accepted in engineering school. Many trigonometric solutions were pages of calculations. We were required to do these without computers, which weren't available or hand held calculators. The precise nature of the work I chose doesn't allow for potentials. Only absolutes.It's obvious that you're an intelligent guy and have been very successful.

The fact that the basic laws of mathematics exist doesn't mean they are relevant today. I would wager,that of everyone that posted in this thread there might be one or two who even know what the sine of an angle is. Calculating seconds of a degree was a process that would take time. Today,with 3 mouse clicks we can measure angles.You might not be as anonymous as you think you are.Comment

7 pages? WTF?Comment

So why are you being so stubborn on this? This isn't an advanced Trig question. This is a middle school level equation. You wouldn't see this in any university level course. It's fundamental math.
Of course the order of operations is still relevant today. If it weren't, how would you know that the brackets come first? How would you know you have to calculate exponents first? Are you suggesting that exponents must also be wrapped in brackets or we couldn't know if they're to be calculated first or not?
As an Engineer it really makes sense to you that at some point somebody decided to make the rules of math MORE complicated by requiring brackets where they haven't been needed for hundreds of years? Should we expect that soon you'll need to write 3^3 in an equation as (3*3*3) so as not to be ambigious when it's well understood already what it means?
You're really maintaining that MOST of the rules of of the order of operations still apply (brackets, exponents, left to right) but somewhere along the line multiplication and division before addition and substraction was dropped from it? Despite all the evidence to the contrary that's already been posted?
I really never would have pegged you as being this stubborn or as somebody that would be trolling in threads but clearly one of those two must be the case here..Comment

order of operations wasn't accepted in engineering school?
id hate to think of how many failed buildings happened because of this fantasy engineering school where order of operations isn't accepted. is 1+1 still 2 there? or is that not accepted?
just because you did that three clicks it doesnt mean that the computer did magic, those basic laws of mathematics still exist today and the computer uses them to process calculations
funny how you are insulting everyone in this thread but you yourself dont know the answer to a simple grade 6 math problemComment

i believe the whole point of this thread is the 'solution' not 'three possible solutions'Comment

How can you be arrogant? There's only one possible solution.
Here's page after page of results from University websites that show you exactly how to do the equation. When following the rules, there's nothing ambigious about it, period.

Go ahead, let us know where you got your Engineering degree. Should be pretty simple to find their math department's order of operations online. We'll follow it and see if we end up with more than one possible solution.Last edited by WarChild; 11-10-2011, 12:32 PM..Comment

If it appears I am being arrogant about a simple math problem it would be because I have done this, in the real world my entire career. Literally I have worked with hundreds of engineers with many fortune 500 companies. So, what you see as arrogance is only life experience. If you go to Martin Marietta for a job and answer the question posed any other way than the way I answered it,you will not get the job. I worked for them right out of school as a data tech and I know that in those years that equation would be considered sloppy and ambiguous. If things have changed in other fields requiring math in 2011 I wouldn't know.You might not be as anonymous as you think you are.Comment

Can you explain the rules that determine when one must follow OOO and when one must not? And is there a reference for that? I can't find one.gone. long gone.

You're being arrogant because you're insisting that you being an Engineer trumps every other source on Mathematics. It's silly on the face. You've been told, and shown over and over again that the Order of Operations has not changed, it demands that in the absence of brackets multiplication and division be done before addition and substraction
So if your argument is going to hinge entirely on you being an Engineer, and having a degree in Engineering, then by all means please tell us where you got this degree from. We can then see exactly how that school, the one that issued your degree, sees things. Shouldn't that be the absolute authority in your mind?.Comment

Man up!
allow me to once again pull from the past....
i took a nice little faceplant in a PHP thread recently. and though i know where my mistake came from, i had to eat crow first. got clowned on for 5-6 pages. but i lived to fight another day and enjoy this thread!

we should call the university of Minnesota and find out if THEY can get this rightComment
-
No need to call them. They've been nice enough to post online the information for any student who might need a refresher.
http://r.umn.edu/academics/advising/...of-operations/
So the Univeristy of Minnesota is wrong because it's a school not an Engineer. I wonder if other universities are also wrong?.Comment

no engineering work but i dont need to be an engineer to know the answer to a simple math problem
it is a straightforward question, BEDMAS means multiplication before addition and subtraction
that is all there is to it.
if someone gave you that question and your answer was anything but 41, you would be wrong. period. wrong.
2 + 4 x 3 = 14
you can't write it as (2+4) x 3 = 18 because then it would be the wrong answer
put it this way, if it were a + bc would you rewrite it as (a+b)c? of course notComment

Don't have a stroke. It's not worth getting so worked up over. I am NOT being arrogant.
If I want to be arrogant,there are plenty of other things that I can be arrogant about. Taking a posture on a math gag I learned in the beginning of my career isn't even on the list.
