48÷2(9+3) = ????

[tre2k4]

Parentheses means multiply.

A ÷ B (C+D)
=
A ÷ B* (C+D)

You do whats inside the parentheses first then divide since the division is on the far left

If it was A *B ÷ (C+D)

you would do the multiplication after doing whats inside the parentheses

 

[MadWun]

Parenthesis first.
then you can't skip across that division to the other side without finishing resolving the multiplication.

been a long time tho.

Same way I am thinking. Dammit, who knows.

 

[half-a-mil]

Order of operation. What's in parenthesis is done first! The answer is 288

 

[IMDATDUDE]

This seems so easy too.

U don't solve the same parenthesis twice in a row

U have to move on to the next step which is division

The 48 has to be tended too


U just can't keep on working on every other number but the 48

 

[jamiemelo]

288

 

[yasky777]

answer should be 48/24= 2

P

[alexw]

wrong!

Are you a elementary teacher?


I am now hush

 

[DipsetBi7ch]

distributive property!

48/2(9+3)

48/(18+6)

48/24

2

Me and this guy went about it in two different methods and got the same answer... The answer is not 288.

 

[marca]

all my math says 2
you guys can roll with 288
and this (48 ÷ 2) * (9 + 3) = 288 which is 48/2=24 * 9*3=12
24*12=288

is not the same question as this 48÷2(9+3) 48/ 2*9+3
48/ 2*12
48/24 =2

 

[doggish_098]

Please Excuse My Dear Aunt Sally?????

 

[tre2k4]

Doesnt make sense

I guess people dont know that multiplication and division are the same and adding and subtracting are the same. Even the calculators and google are saying 288...See http://lmgtfy.com/?q=48÷2(9+3)&l=1

So whatever comes first, you do it first. You dont multiply then divide when division comes first.

5 ÷ 5 x 6 =6
5-5+6=6

Please Excuse My Dear Aunt Sally?????

Aunt Sally's a Ho.

 

[alexw]

Me and this guy went about it in two different methods and got the same answer... The answer is not 288.

Thats exactly why both of you are wrong

 

[MadWun]

My old lady just did it too. She gets 2.

I didn't say shit to her but provide the question.

 

[KingFoo]

Answer is 2.

This is how you get it:

1. Sort out what in the brackets (that is the rule) first:

So you get: 48÷2(12)

2. And 48÷24 = 2

 

[trick20]

You got it wrong homie.

48÷2(9+3)

Parentheses first

(9+3) = 12

THEN YOU HAVE 48/2(12)

After that you work left to right

24(12)

288

Multiplication and division are the same, therefore you work right to left after you do the parentheses.

Least that's what I recall lol. I could be wrong.

thats how i remember it

5-5+6=6

Google isn't perfect. I came up with "2", then I punched the problem in a scientific calculator to make sure and the answer is also "2".

Niggas need to pay attention to aunt sally.

 

[stizz3000]

Wow this brought out my memory on "Please excuse my dear aunt Sally" pemdas.

WOOOOOW.......That shiit was deep deep deep in the memory bank..LOL

Thanks

 

[doggish_098]

Maybe when my students say my parents didn't know how to help me with the homework they are telling the truth

 

[tre2k4]

The only way to come up with 2 is if you add a parenthesis
48÷(2(9+3)) =2
without it
48÷2(9+3) = 288


(P=E) (M=D) (A=S),If they are the same, you just work them left to right.


"multiplication and division are of equal precedence, as are addition and subtraction"

 

[KingFoo]

answer should be 48/24= 2

P
e
m
d
a
s

I also got 2 using what we call BODMAS down here. Which means:

B = brackets (meaning that the brackets must always be sorted out first)

O = off [ like 5% of 300]

D = ÷

... It doesn't matter which comes first between ÷ and *. Same thing applies with + and -.

But what does PEMDAS mean? What are the P and the E stand for in your method?


Edit: Just saw the post by Nobody...

 

[BigDaddyBuk]

well, my answer was two cause you dont go from left to right until you solve every thing on opposite sides of the equation.

at least thats how i remember it.

 

[cooliojones]

Funny you say that. I was thinking that the other day, that when I have children I'm going to have to pretty much go back to school from scratch.

Anyway, PEMDAS is

Parentheses, Exponents, Division, Multiplication Addition, Subtraction.

At the least it would break down to

doing the (9+3) first (parenthesis) -- 12

Division - 48÷2 -- 24

Multiplication - 24*12.

By your own words, you still messed up.

You put the acronym for PEMDAS, but put multiplication before division.



Dyslexic?

Well Mr. Elementary teacher, please teach them kids proper mathematics

 

[KingFoo]

Dyslexic?

It doesn't matter which comes first between division and multiplication. . Example 4 * (4/2) = (4*4)/2...

 

[stizz3000]

when I looked at it and did it in my head, I got 2

48÷2(9+3) = 2

48 divided by 24 (2 times 12). you do whats in the parenthesis first, and a number next to the left of parenthesis means multiply without using the actual *

Thats the way it was taught to me years ago

 

[catalina74]

...2 ....

 

[tre2k4]

By your own words, you still messed up.

Dyslexic?

it just means multiplication and division come last after the first 4. It could be PEDMSA

 

[lightweightplaya]

Kinda disappoints me that 2/3 of the board got this wrong.

 

[Nobody]

48÷2(9+3) =
48÷2(12) =
48÷24= 2

Fuck it, I'm back.

Division and Multiplication are rated the same by PEMDAS.

Therefore you'd do the parenthesis, then work left to right.

You don't do the parenthesis, then work right to left. Had it been written expressively as 48÷(2(9+3)) then it would be 48÷(2(12)) or 48÷24.

But you operate by doing the parenthesis first 9+3 and you get 12.

Then you move from left to right and solve the equation.

Go into google and copy the OPs equation then copy 48÷(2(9+3)) and compare the answers you get.

You do what's in the parenthesis, then exponents and THEN you work right to left doing mutiplication and division based left to right, and subtraction and addition left to right.

Now if it were 48 - 2(12) then you do the multiplication FIRST.

But since there's only division and mutiplication left you work left to right after doing the parenthesis which is the priority.

 

[charlie dark]

The answer is 2....

Next question please...

 

[SaKem]

i too thought it was 2 but that was until i was getting different outputs.
i even busted out my ti-83 and it's output was 288.

You must have entered it wrong. A lot of people don't know how to use the ti-83 properly

 

[tre2k4]

niggas dont know about the equal precedence rule.

 

[SaKem]

There are a lot of Dumb people on BGOL. I was thinking about giving a calculus question to the next person who thinks they're so smart.
