absolutely NOT. a parenthetical equation ALWAYS takes priority.
Another example:
2*3+4 vs 2(3+4)
Answers are 10 and 14, respectively. HUGE difference.....

After completing inside the parentheses, you work the equation from right to left based on the order of operations.

Now apply that you just did above to the OP´s equation.
 
nope. just undergrad dual major in finance and stats, and then a masters in accounting with a tax minor.

:dance::dance:
I see. You barely passed algebra or maybe you don't use it often enough because you failed this math problem. You might take a refresher algebra and precalculus course when you have free time. Or maybe shoot one of your professors this equation. You will be surprised :)
 
Simplifying Using the Distributive Property Lesson

The Distributive Property is an algebra property which is used to multiply a single term and two or more terms inside a set of parentheses. Take a look at the problem below.

2(3 + 6)

Because the binomial "3 + 6" is in a set of parentheses, when following the Order of Operations, you must first find the answer of 3 + 6, then multiply it by 2. This gives an answer of 18.

2(3 + 6)
2(9)
18

you have to get rid of the parentheses first. before you can move on....or you have to distribute across the parentheses to get rid of them. You can just leave the parentheses there. that is the mistake all of the 288ers are making.....you have forgotten that rule.
 
lol the answer 2
Its 2 if its true that 2 times (9+3) outranks division

Im done
Absolutely, it is true. That is the difference. people with BOTH answers have said that the parentheses outranks anything, so I don't get why there is all the confusion simply because we are multiplying parentheses by 2...
 
Why has no one provided proof that a number in front of parentheses must be multiplied before anything else can be done????????

Distribution holds the same weight as multiplication in the order of operations because the distributive property is multiplication.

:smh::smh::smh::smh: If you interview programmers and they get 288 you have a real idiot on your hands.

again according to http://www.purplemath.com/modules/orderops2.htm

= 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 left-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.

just a note all math scholars across most forums with this problem all agree the equation is written poorly leading to this debate. it should either be;

(48/2)(9+3) or 48/(2(9+3)) however as it is written it is 2.

when you add the 9+3 =12 a * doesnt separate that 2. you would have 48/2(12). the parentheses still has to be resolved before you can divide.
If this the only source then by this logic its 2.

So that would mean 1/2(2+3)
isnt the same as 1/2(5)

It doesn't make logical sense

I want to draw some type of conclusion from this. Seriously, refrain from degenerating this into insulting. I will as well.

Can you please provide the rule that explicitly states that you have to distribute across the parenthesis?

Because you are stating that the 288 crowd has forgotten this 'rule'.

The order of operations states that you do the parenthesis first. You then do any work with exponents or radicals... and then you work the problem left to right doing all multiplication and division...then additions and subtraction from left to right.

This is the order of operations. That is the rule.

In the OPs equation, distribution holds the same weight as multiplication in the order of operations because the distributive property is multiplication.

So that is how you come to an answer of 288.

Now can you please state the rule that you have to distribute that two accross the parenthesis? I mean quote the rule.

We need to stop with this name-calling shit..even though it is funny.

This an argument over the misinterpration of mathematical rules that comes to life because of the way in which this equation is written. However, I don´t think it is that ambigious. I think a rule is being credited to solve the problem that isn´t a part of the order of operations. But some people are arguing intelligently on both sides but I think the mnemonic is causing problems here.

Simply because there are hardly any evidence supporting x(y) > z/x

Theres plenty supporting (x+y) > x*y or x/y

How old are you? 45? or something right? You should have learned that type of stuff in the 3rd grade.

Simplifying is done before you do ANYTHING!


when i said proof i meant a source that says that if you have 2+3 ÷ 4 * (6+3) -8, you must multiply 9 by 4 first instead of dividing 3 by 4.

no one disputes that 2(3 + 6) = 18, but that does not prove what you are saying either.

If you and i had 36 ÷ 2(3 + 6), what source specifically says that i'll get 2 instead of 162?
 
First I think the vids people posting with calculators, prove nothing.

because understanding and interpreting a problem is relevant when doing these types of computation on your calculator.

My Ti-Nspire CAS has the ÷ notation as / and the answer came out to be 288.

I probably could count the times I see or use the ÷ notation
I still think it is poorly written.

tre2k4 provide some valid arguments

Any source that correctly states you must Simplify when you're presented with a number in front of the Parenthesis. They teach that in 3rd Grade.


36 ÷ 2(3 + 6)

= 36 ÷ 2(9)

= 36 ÷ 18

= 2

Why would you buy that calculator if you don't know how to use it, and you don't know basic math?

Because your calculator isnt Simplifying you fucking numskull...
 
Dog, (9+3)=12...its already simplified after 12...there is no more simplification to do. Its then entire problem is re-evaluated from left to right

You can't not finish the operation then skip around to other parts of an equation idiot. :smh: The 2 is part of the simplification of the parenthesis. I'm kinda upset that people are this stupid. This is unacceptable like wtf is going on in this country.
 
Why is it that the people who say the answer is 288 have shown data and proof to back up their claims, but those who've answered 2 have given no proof (just insults)?

1/2(2+3) certainly DOES equal 1/2(5)...both of them have parentheses so those equations must be solved first....same as in the original equation...get rid of the parentheses THEN you can divide.

Theres plenty supporting (x+y) > x*y or x/y
what you typed here is not equivalent to what's in the original equation. A better example is the following:
x(y) and x(y+z)...they both will take priority over division...
x(y) = xy and x(y+z) = (xy+xz)....
Exactly. I want so see the definitive evidence that says x(y) > z/x in the order of operations.

36 ÷ 2(3 + 6)

= 36 ÷ 2(9)

= 36 ÷ 18

= 2

36 ÷ 2(9) = 36 ÷ 2 * 9

= 18 * 9

= 162
