Incorrect.

There is nothing to perform within the parentheses.

Your equation is essentially -10÷2*5 = -25
the equation involving the parentheses is 2(5). Period. You must simplify ALL parentheses before moving on to any other operation. :)
 
:lol::lol::lol:

I watched that at least 10 times before so I thought I'd watch it again for fun. I was eating my Reese's Pieces and the end caught me off guard (because that was never part of the original video) and I damn near choked.

its the special "followup" edition.

:roflmao::roflmao::roflmao:
 
Explain to me how writing 2*x as 2x gives it more priority.
As I stated several pages ago, 2x and 2*x have only one operation. There is no ordering, no prioritizing. All you have to do is multiply the 2 things.

In the same sense, when you have 2x/y, there is no need for ordering ooperations because multiplication and division are of the same order. You can choose to divide first or multiply first and you will arrive at the same answer.

Now when you add parentheses, exponents and addition/subtraction, the confusion comes in...hence, a 30+ page thread which was answered correctly on page 1. :dunno:
 
the equation involving the parentheses is 2(5). Period. You must simplify ALL parentheses before moving on to any other operation. :)
And the parentheses acts as multiplication. There is nothing within that "group" that needs to be simplified as it already is.

You are confusing 2(5) with (2*5)

Stop being dense.
 
This statement is part of the reason why 40% of responders get this problem incorrect. You are relying on the power of a machine to do your thinking for you. If the user does not know how to use the machine, the machine is worthless, no matter how much the user paid for it. :)

You would be a fool to believe that I ran directly to my calculator to discover the answer. I see the answer by looking at it. The calculator was used to support my answer. If my calculator said two, I still would not believe it.

I'm pretty sure that have enough experience with these "machines", being a defense engineer and all. Just sayin.

Now get the fuck outta here with that bullshit!

Next lesson:
2x=2*x=2(x) only 1 operation...no need to order them
3+2x=3+2*x=3+2(x) 2 operations to order. multiplication trumps addition in each

1/3+2x only 2 operations
1/(3+2x) 3 operations

1/8(3+2x) 4 operations
PEMDAS 1/(24+16x)

1/8(3+2x)^2 (5 operations: you will square what's in the parentheses first, then multiply all of that by 8, then divide 1 by all of that)

LOL! IRON-E

the parentheses is obviously multiplication. As far as I see, nobody is debating that :confused:

What YOU will not accept is that the multiplication that comes with parentheses is of a higher order than multiplication with a times sign. Math is a universal language and some of you do not speak it :dunno:

http://personal.carthage.edu/tgroleau/AlgebraReview/Section04.html

once again...(they also address the problems with calculators and orders of operation)

EDIT:
"Calculators and the Order of Operations


Most non-graphing calculators either automatically follow the order of operations or give the user the option of setting the order followed. However, some old calculators
and some very inexpensive calculators ignore the order of operations and simply calculate items in whatever order they are entered.

You can do a quick test to see how your calculator works. Enter the following problem: 3 + 2 × 4 and check the answer. If your calculator automatically follows the order of operations you will get the correct answer of 11, (2 × 4 = 8, 3 +8 = 11). If your calculator does not follow the order of operations you will get the incorrect answer of 20, (3 +2= 5,5×4= 20).

If your calculator found the correct answer, then you have little to worry about. You can enter problems as they come throughout the semester. However, if your calculator found the wrong answer you will have to be very careful when entering problems. You will have to determine the correct order yourself and enter them into your calculator accordingly."

I did this yesterday and I pretty much got the answers I was expecting. My friends in software engineering told me to rewrite if I wanted the answer to be 2, while a lot my mechanical folks said that it should be 2, but when asked if they disagree with it being 288 they went back to I don't know. With programming, the problem has laser precise, that is why programs like matlab force you to enter 48/2*(9+3) instead of 48/2(9+3). It doesn't recognize it because of the ambiguity, this then forces whoever the operator to make a decision and be clearer about their intentions.

this is math. not engineering. and this is BASIC math at that. We would expect that our engineers, supposedly the best and the brightest, would be able to come to the correct solution to this problem: 2. If any of them answered 288 seeing the equation AS IS, they should re-evaluate themselves.

You are missing my point. It's all about the parenthesis, programmers see 48÷2(9+3) and 48÷(2(9+3)) as two very different things. There is a reason why we have seen all over the internet, that this argument never ends. So roll with your 2 if you want, that's fine, but you damn sure are not in a position to tell others to re-evaluate themselves with all of the dumb shit you have said on this thread. If you are going to debate on such a basic concept, don't get get caught saying any ignorant shit.

Do you though!

LOL!!! Quote all of the dumb shit I have posted in this thread please. Thanks.

I came to the correct answer in 5 seconds, while you STILL do not get it. I am in a better position than you to tell you to re-evaluate yourself (and your math skills). The equation is typed as 48÷2(9+3). Not 48÷(2(9+3)), so right there you can stop. There are 2 math principles that will lead a person to the correct answer:
Distributive property & PEMDAS. Period. You try to forget about either of them, you will arrive at the wrong answer. Ok? *waiting for your quotes of my posts*. Thanks.
 
All the accusations of ignorance and jest make you no more right dude. I put this problem in front of a 7th Grader, he said "PEMDAS" and solved it to 2. I put this in front of a Finance major, she said "PEMDAS" and solved it to 2.


1. I didn't even read Tre2k4's waste of time post.

2. I didn't read that shit either.

3. That video explains Simplifying and the Order of Operations to your silly ass.

4. Suck my dick and gargle my balls.


I think the "logical ones" or really just the people that agree with you have decided to distance themselves away from your black ass who:

Can't see the connection between the OP original problem and related examples, even when the support your argument, let a alone the ones that don't.

Takes it upon yourself to hunt down a video clip of a person performing the order of operations correctly in an example that truly has no relation ship to the original problem or related examples. Proving your lack of understanding of the actual debate between the 2 and the 288.

And you refused to address questions that could possibly vindicate you from your ignorance.

The actual debate has been over for a while many of us who were on one side or the other have decided to admit that the way the problem is written, there is room for different interpretations.

What's been happening for the last several hours is folks discovering that you, one of the main contributers to this debate is a total dumb ass who had no business in the discussion from the jump.

This will be over when you stop posting and displaying your ignorance. I won't stop nigga, I won't.

So lets try this again EVEN THOUGH I KNOW YOU WON'T ANSWER IT

But Ima try to make it painful as fuck for you to keep glossing over!

1) CAN YOU EXPLAIN HOW THE EXAMPLES POSTED BY tre2k4 ARE DIFFERENT FROM THE ORIGINAL PROBLEM?

2) CAN YOU PROVIDE ANY UPDATE ON THE HOMEWORK ASSIGNMENT THAT NOBODY GAVE YOU?

3) WHAT THE FUCK DOES THE VIDEO HAVE TO DO WITH THE ORIGINAL PROBLEM?

4)

The explanation of Implied Multiplication and why it leads to confusion.

With these types of problems, the answer can go either way. No one has came to an agreement about the rules.

Its all conventions. Conventions a rules without explanation.

Implied Multiplication isnt applicable all the time

Order of Operations Dispute



Date: 09/26/2000 at 21:03:38
From: Doctor Peterson
Subject: Re: Order of Operations Dispute

Hi, Terre and Robert.

Let's write the problem as

n / ml, with n=12, m=6, l=3

I can give you some good news and some bad news. First, the bad news:
according to the usual order of operations rules now taught, your
answer is wrong. You can read about the rules in the Dr. Math FAQ:

http://mathforum.org/dr.math/faq/faq.order.operations.html

Basically, you do all multiplications and divisions before all
additions and subtractions; and when you have a string of
multiplications and divisions to do, you go from left to right in the
order they come. In your case, that means you divide n by m giving 2,
then multiply by l to get 6.

BUT...

You are not alone in your opinion. This part of the rule - doing
multiplication and division together - is probably the last rule to
have stabilized; I know that in the 1920's, at least, there was no
agreement. It seems that an agreement developed, but it is unraveling
now, as I hear from many students whose texts answer questions like
this the way you did. It appears that they are adding an unstated
rule, which seems entirely reasonable in this context, that an implied
multiplication (indicated by simply placing two variables or
expressions together, as in "ml") should be done first. It certainly
looks as if it should mean that. The problem is that, although I've
heard of this rule being followed frequently, I've hardly ever heard
of it being taught, so these texts are not following their own stated
rules.


Since this type of expression is so ambiguous, with people disagreeing
on the rules, and the rules being easy to overlook, my own opinion is
that neither your answer nor the teacher's is right:
the question is
wrong. No responsible mathematician would write such an expression; we
would just say

n
---
m l

so there would be no question about its meaning. After all, the
purpose of rules is to allow us to communicate clearly, not to help us
trick students and start fights among families.

So you may in fact be "old-fashioned"; or you may be on the cutting
edge. In any case, I'm afraid you'll just have to learn how they are
doing it in class, and follow along. There shouldn't be many more
issues like this to worry about.

You can read more about these issues in the Dr. Math archives:

I hope this helps at least a little.

http://mathforum.org/dr.math/

Order of Operations

It is important to realize that the implied multiplication coming from juxtaposition
has an equal order of precedence with explicit multiplication is some models but in other
models it has a higher order or precedence. Consider the two screens below. In both
cases the same keystroke sequence is used, but the results are different.

One of these screens is from a TI-85 and the other is from a TI-86. There are several
morals to this example. First of all, teaching students to use a calculator on a keystroke
by keystroke basis is not a good idea. Second, the instructor should avoid using this
construction of a division followed by an implied multiplication. In fact, even though the
instructor will typically be thoroughly familiar with the precendence relations it is not a
good idea to take advantage of this knowledge in order to save a keystroke or two. A
better idea is to always use constructions that will be interpreted the same way by any
model.
In this case you could use 1/(2x) or (1/2)x depending on which expression you
want. The third moral is that this problem will come up in your classroom. When it
happens it can be used to advantage. Use this issue to emphasis appropriate use of
parentheses.
An interesting aspect of this is the distinction between -22 and (-2)2. This is one
place where TI is consistent across models. In every case, exonentiation takes
precendence over negation. As a result, for TI -22 = -4. This is an important fact to
know when you are dealing with a beginning College Algebra student. This convention
is useful because it makes the result that appears on the TI screen consistent with the way
we write things by hand on paper or on the blackboard.
