Half of you will get this wrong: 48÷2(9+3) = 288 or 2?

[AKIRA]

Go.

Use properties, use links, use pics.

288

 

[Zaphod]

2 Order of operations.

 

[Imosted]

^^^ this
9+3=12
12*2=24
48/24=2

 

[DOMS]

2 Order of operations.

Yep.

 

[ihateschoolmt]

I believe 288 because when there are two options like with 48/2x12 you work it left to right. That's what I was taught, and when I tutored algebra that's what I told kids to do so I hope that's right

heres a problem with the same dilemma.

Yup. I was wrong.

Three! Ooh! Pick me! Pick me!

Wait. It's 12.

Nooo. Don't tell me. A MILLION!

Two million?

288


48/2 = 24
9+3 12
12 x 24
288

Fuck! I hate being wrong.

But you have to appreciate the beauty of math. Had this been an abstract concept, we would have a 20 page thread on our hands with flames and death threats between the divided groups of twoions and twohundredandeightyeightions.

Please Excuse My Dear Aunt Sally

You're making the mistake of thinking My Dear = Multiply then Divide when the rule is Multiply Or Divide depending on order of appearance from Left to Right...

Well I was spoiled by my TI-92.

I think problems like this along with my dyslexia caused me to fail Algebra the first time around, because I am such an abstract thinker, I'd confuse myself until a teacher who saw that I could figure out the If, Then, Else & And/Or of computer programming with ease showed me the exact logic....

 

[Curt James]

48÷2(9+3) =

That whole order of operations things sounds vaguely familiar.

But I thought you would do the division thing for 24 then do the addition thing for 12 and then multiply 24 and 12 for, uh...

I'm an art teacher. I can draw a calculator but don't ask me to use one!

Of course they say that art and math are closely related, so...

Mathematics and art - Wikipedia, the free encyclopedia

Anyway, my vote is for 288.

Believe I had a C or D in pre-Algebra. Dropped Geometry because I disliked the teacher.

But gosh darn it, I got an A in illustration!

 

[MDR]

288-and I be an Engllish Teacherr.

 

[LAM]

are you not to assume that 48÷2(9+3) equals (48÷2(9+3))

I'm going with 2

 

[Built]

288

 

[bulldogz]

48 ÷ 2(12) = 2

 

[danzik17]

288.

 

[Diesel618]

lol @ retarded people.

It's definately 2.
