Come on Math wizards 48÷2(9+3) = ???
 

Yes i know the answer just interested to see how people here do

72..........

It's also an eye test since it looked like two plusses at first! I think it's 2.

Ah, the foil method.

Answer is 2.

2

:2 cents:

i like robot chicken

(48 ÷ 2) * (9 + 3) = 288

288
I like turtles

288

either or, neither nor, depends on how you work the math problem.

I was taught to work left to right, so do the ( ) then work the x and ÷ from left to right.

Edit: Apparently I'm wrong.

I didn't think an extra set of parentheses were required when it was a multiplication outside a combination, but they are.

twelve?

It may well do, but that wasn't the equation in the OP.

Fuck!

I don't think they are.

I thought you did the inside parens first, then the missing operand is multiplication, then the left side is divided by that result, equals 2.

But I was a pretty bad student. And back when I was in school, calculators didnt exist yet.

Some of you need to review your orders of operation

1) Terms inside parenthesis
2) Exponents and Roots
3) Division and Multiplication
4) Addition and Subtraction

My maths breath smells like math food.

or 600


if not both then GFY.

You move from left to right within each level of the order of operations.

Yeah, I was getting it screwed up with something else and was putting that as #1 before parentheses.

I actually look forward to when my kids get into algebra. I was great at it and still love numbers, a little refresher will be good too. :)

you do the formulas within parenthesizes first, then on the outside going right to left. multiple and division are equal as addition and subtraction are.

Meaning... 48 / 2(9+3) reads 48 divided by 2 times the sum of 9 plus 3

wow....this is awesome..lol

keep it coming folks...hopefully some of you aren't working in your accounting departments ;)

.

288
48/2 = 24
multiply that for 12 = 288

Seriously. Order of Operations people. I suck at basic math, addition, subtraction, mult/div, algebra, etc, but for some reason I can do advanced math, trig, calc, etc.

2 & 288 :)

come on, we all know to google :D

Math? As if...

2, you do the parentheses first, then multiply and last divide... :winkwink:

You should have made this a public poll.

----------------

haha many wouldn't take part if it was

look bryan declared he likes robot chicken ;)

Negative.

Multiplcation and Division are equal not multiply before divide. :)

3.1415927. I rounded it.

How does the original equation vary from what he posted? They're the same, aren't they? He added in the parenthesis to help demonstrate the order of operations.

2 gets my vote

as you know most answers are

pi
pi/2

0
1
-1

those are all decent guesses..lol

That I know, done left to right. :)

this is where i went wrong :P

2(9+3) is assumed to be (2*(9+3))

if it was written 2*(9+3) it would not be the same

:2 cents:

It's not quite as effective without the images.

I think a lot of people get confused on this.

The reason why multiplcation/division and addition/subtraction are grouped at the same level and of equal improtance is becaue they're essentialy the same operations.

5/1 = 1*5
2-1= 2+ -1

At least that's how I remember it being explained.

48 ÷2 x 12

gah i'm dumb

i didnt see an image where i got it from

wait maybe you mean this one

Wow this thread blew up :P I am pretty sure I did It right though. Or maybe I need to get back to school? :Oh crap

288 cents is what I needed.

i was just forgetting the rules and thought that 2(12) took precedence for some foolish reason

my old math teacher Mr. Ramsey would slap me

oh its getting good

soon someone will try to prove the rational number system :)

I'm fairly sure you did it right too. I haven't been to a Math class in a good number of years though so who knows maybe we're both wrong.

trick question!
