Oh snap!

Wait, It isnt! Doesnt account for PEMDAS!

I'm kinda starting to feel like I didn't do right by you. Son I shoulda came around a lot more when you were growing. You know how moms is though. I wasn't much of a father.

You're getting silly now, so Im done engaging you. You're so confidant in you ignorance you're embarrassing yourself homes. :smh:

No you've been done since you dusted off that old ass calculator and tried to drop knowledge. Talking about blaming inner city schools and shit. Nigga all my degrees have come from and will come from top 5 or better schools in this country. You joke my about education, but get moist when I joke about your possible shortcomings, due to being a fatherless bastard. Don't joke if you can't take it.

So basically you go out looking like you don't understand that pemdas is the order of operations. You had no right engaging me with bullshit like that.

:lol::lol::lol::lol::lol::lol:
 
Whats not to understand about PEMDAS? Whether you use PEMDAS or the Distributive Property the answer is 2 nigga.


Whats all this Fatherless shit you throwing around nigga? What the fuck does that have to do with what we're talking about bitch nigga? Both my parents were married and present in the home. Were yours? It sounds like you're telling us about your life fam. You dont even know who your father do you? :smh:


And degree my ass nigga. What type of nigga with a degree doesnt understand some simple shit like Distributive Property? :smh::smh:

You've made the first valid point here (the mathematical answer you gave). But with this said, it seems as if the person who posted the problem posted it incorrectly and we need to know what the intention was. Because it should have been written like this:

48
2(9+3)

if the answer was meant to be 2. But because of the way it was written, the debate begins because I know we've all seen this:

a(b+c)=ab+ac

Which is not really Pemdas, but a shortcut that gives the same answer. I've still seen no one post the actual theory that states that because the 2 is touching or next to the parenthesis, it becomes independent of the 48 even though the purpose of the parenthesis around (9+3) is to clearly show that it should be separate from the 2. So I think that to answer how it is written is 288, but if the answer is supposed to be 2 then it should have been written differently.
 
this the correct way!!!!!!!!!!!!!
:yes: since page one. People are trying to put division over an equation involving parentheses. :dunno: it's bgol & we're ALL competent in math so therefore this equation has 2 correct answers :smh:

Ever wondered why Asians LOVE having corner stores in black neighborhoods?

What dumb ass nigga doesn't understand that because the 9 an 3 are both integers, you don't use the distributive property. Nigga you add the 9 and the 3, you get 12. WHAT THE FUCK IS THERE TO DISTRIBUTE? Furthermore, if you use the distributive property, you won't be following PEMDAS.

I know notta damn about your family, just like you know notta damn about my education. I took your inner-city comment, as a joke, and took a shot at your upbringing in a joking manner. You got moist and upset.

You can distribute 2 over 9 and 3 which gives you the same answer as 2 times 12.

You can't do it here because it violates PEMDAS. So it's fuckin useless here.

BTW, moms and pops are cool, just like yours.

This is 2...

48÷(2(9+3))
 
Nathan when you simplify 48/2(9+3) it is 48/2(12) not 48/(2(9+3))
That is where the problem is. Distributive property does not come into play with this equation because there is a division sign that starts the equation. 48/2(9+3) when simplified is 48/2 * 12 Here is an example from a different website purple math.com

A common technique for remembering the order of operations is the abbreviation "PEMDAS", which is turned into the phrase "Please Excuse My Dear Aunt Sally". It stands for "Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction". This tells you the ranks of the operations: Parentheses outrank exponents, which outrank multiplication and division (but multiplication and division are at the same rank), and these two outrank addition and subtraction (which are together on the bottom rank). When you have a bunch of operations of the same rank, you just operate from left to right. For instance, 15 ÷ 3 × 4 is not 15 ÷ 12, but is rather 5 × 4, because, going from left to right, you get to the division first. If you're not sure of this, test it in your calculator, which has been programmed with the Order of Operations hierarchy.

I posted multiple links a few pages back that demonstrate it. College/university sites...

These 2 equations are the same. Go back to page 2 or 3 of this website you posted and they go through problems with parentheses. In every single one, they get rid of the parentheses before moving to either multiplication or division. Also they ahow some of you who never made it to precalculus or calculus (and really should not even own a graphic calculator because of that fact) how to enter equations CORRECTLY into graphing calculators using algebraic laws :)
 
Nathan another way to look at it, if you want to use the distributive property is...

24(9+3)

24*9 + 24*3

216 + 72 = 288

You may see it now.

The only thing in the parentheses is 9+3 everyone solves that first. Then you have 48/2(12) pemdas, bodmas order of operations they say go left to right. Why are we hung up on that part? We don't do 2(12) first because it goes against the order of operations. if it was 48/(2(9+3)) then you would have (2*12) which is 24 then 48/24 would be 2 but with the way that this problem is written the only thing in the parentheses is 9+3 with the start of the equation 48/2*(9+3)because there is no extra set of parentheses to make the 2 apart of the

hey, don't take MY word for it. go back to the website YOU posted. then hopefully you can see your mistake and then explain it to others who don't understand, yet won't pay attention to others on the board :)

no no no no no! goddamn you smart dumb niggas. the problem is treated that way BECAUSE of the division sign. until otherwise stated (by an additive or subtractive property) all terms under the DIVISION sign are treated as one entity. get some math in your life. FUCK YOU NIGGAS! I'M DONE! :lol:


check this out though: if i add a divisor into your equation and a 1...

a/1(b+c)=????
good luck :lol:

The 2 is part of the Parentheses since there is nothing in between it and the (). The () owns it, and you multiply (or Simplify) it. It represents a single expression.


What you're doing is telling me how to make it work on a calculator.. What Im telling you is some calculators dont recognize Simplification. Why? Because what are the intentions when you put an invalid problem in a calculator like this?


What Im telling you is this is an invalid problem... Until you Simplify.

Entering equations in to calculators is really similar to entering them in to programing languages. It's really something you have to pick up on early or you will be fucked. The think about the higher end calculators is they have something called pretty print. You enter the expression, as you would in matlab or other higher level languages and the expression comes out like you would expect to see it written down, or in a book. This way you know the system knows what expression want to evaluate. The 89's and 92's were the first ones to do this. This is a huge advantage over an 83 or 84.

I think that kids in algebra should not have an 83 or 84 until calculus. Unless they are taking stats. Students in calculus, should not have an 89 or 92 unless in an engineering class, or Diff Eq.
They need to learn how to do thing by hand, until they are comfortable without help. Those calculators are too powerful, and they do everything for them. And it only gets worse, if they don't know how to use them.

This next example displays an issue that almost never arises but, when it does, there seems to be no end to the arguing.
Simplify 16 ÷ 2[8 – 3(4 – 2)] + 1.
16 ÷ 2[8 – 3(4 – 2)] + 1
= 16 ÷ 2[8 – 3(2)] + 1
= 16 ÷ 2[8 – 6] + 1
= 16 ÷ 2[2] + 1 (**)
= 16 ÷ 4 + 1
= 4 + 1
= 5

The confusing part in the above calculation is how "16 divided by 2[2] + 1" (in the line marked with the double-star) becomes "16 divided by 4 + 1", instead of "8 times by 2 + 1". That's because, even though multiplication and division are at the same level (so the eft-to-right rule should apply), parentheses outrank division, so the first 2 goes with the [2], rather than with the "16 divided by". That is, multiplication that is indicated by placement against parentheses (or brackets, etc) is "stronger" than "regular" multiplication. Typesetting the entire problem in a graphing calculator verifies this hierarchy:

order12.gif


Note that different software will process this differently; even different models of Texas Instruments graphing calculators will process this differently. In cases of ambiguity, be very careful of your parentheses, and make your meaning clear. The general consensus among math people is that "multiplication by juxtaposition" (that is, multiplying by just putting things next to each other, rather than using the "×" sign) indicates that the juxtaposed values must be multiplied together before processing other operations. But not all software is programmed this way, and sometimes teachers view things differently. If in doubt, ask!
(And please do not send me an e-mail either asking for or else proffering a definitive verdict on this issue. As far as I know, there is no such final verdict. And telling me to do this your way will not solve the issue!)

In summary, this is a problem where you can use your brain to solve it. But if you choose to use a device, please know how to use the device. Thanks.

Look man, no need for insults patna. I guess if you're wrong about any subject in life, then others have the right to call you dumb...so are you saying that parenthesis supercedes the division theory.

(48/2)(9+3)

Or does this still equal 2?

I got you, this is what that website says right below the example that you are talking about

We're not ever going to get to the bottom of this problem at least not from that website.
