@Shady

Maybe it is 288…

How Do I Remember It All … ? PEMDAS !
PParentheses first
EExponents (ie Powers and Square Roots, etc.)
MDMultiplication and Division (left-to-right)
ASAddition and Subtraction (left-to-right)

For some reason I dont remember it having to be left to right I thought MULTIPLICATION always came first… but if thats wrong then it is 288…

IIRC It doesn’t matter what comes first multipication/divison wise all that matters it from that point on you work the problem L>R.

Ive never edited something so fast in my life

Going with 288 if that is how much I overpay IRS

or

2 if that is how much I owe them

amirite or amirite? :rofl

:rofl nicely played

Lock it up… thank god

Distributive property of multiplication over addition. Early Algebra problem.

The distributive property of multiplication CLEARLY states that the 2(9+3) is an entire statement and CANNOT be broken up. 2(9+3) follows the distributive property which can be rewritten as (29+23). Let me repeat the 2 outside of the parenthesis follows the distributive property of multiplication and must be factored and simplified before performing any other operations on it. You do NOT compute this expression from left to right until you use Algebra to simplify the statement 2(9+3).

So this can be rewritten as:
48 / (29 + 23)

Which leaves us with

48 / 24 = 2

Answer = 2.

Lastly for those using Google or any other online calculator. These do not understand many theorems or properties so you must explicitly explain what you mean. There is a difference between 48 / 2 * (9+3) and 48 / 2(9+3). The first notation reads 48 / 2 * 1(9+3) while the second reads 48 / (29+23). Be very careful with your signs.

You win by quoting someone else’s answer on yahoo, and i think i saw it on another forum.

The part in bold isn’t actually a rule. It is just whether you assume implied multiplication comes first or not. There is no rule that states it comes first, and it seems half of calculators do it first, and the other half dont. I have 2 calcs on my phone that give 2 different answers.

Look up my further quotes of the RULE of the distributive property of multiplication.

I picked his quite because he put into technical terms what I couldn’t, as I wasn’t here in America for that part of basic math education so I never learned these terms in English.

But that it is the way I was taught and that is the way it works.

Otherwise you’re breaking the rule of the number that’s assigned to parenthesis being applied to each number inside with the addition

PE (MD [L-> R]) (AS [L->R])

how bout this. ill bring the question with me to school tomorrow and have a math teacher and her students do it.

48÷2(9+3)=?

48÷2(12)=?
48÷24=?
2=?

[bennyfizzle]

I too will be asking my prof tomorrow night.

[usmc2801]

Someone please find me where it says work left to right on a math problem for all of you who think 288 is the answer…

My fiance who has a masters degree and had nearly perfect scores in EVERY math course she ever took said the answer is 2.

Reasoning: 48÷2(9+3)= is to be separated into two parts
The ÷ symbol separates the problem
so you have 48
and you have 2(9+3)
which results is 48÷24
=2

She said working you don’t go L to R until both sides of the equation are solved.

[usmc2801]

Oh and I will take my fiance’s word over any professor because she prolly makes a lot more money then ANY of them LOL

The square root of 69 is 8 somethin…?
