how is it that a lot of people come up with 2? is it because they dropped the brackets after adding the 9+3?

how is it that the answer is 2??? are you talking about the same previous question?

- anonymous

Its because the multiply the 2 by the 12 and get 48/24 but thats not how its works. For you to multiply the 2 by the 12 it would have to look like 49/(2*(9+3))

48/2(9+3)????

- anonymous

thats not how it looks....it looks like this 48รท2 (9+3) = ?

- anonymous

Then its very ambiguous and i would argue with your teacher.

- anonymous

yeah, it all depends how u look at it. Is this a math problem from a book or one that the teacher gave out?

- anonymous

If i were to do this problem I would see it as (48/2)*11

- anonymous

That would be 264

- anonymous

are your classmates getting two????

- anonymous

How do you get 11....... 9+3 is 12, i think we can agree those brackets are done first.

- anonymous

cause if they did it this way then: 48/(2*11) will give you 48/22

- anonymous

wow, my bad. I need to check my eyes........lol

- anonymous

yeah so it would be (48/2)12 which would be 288

- anonymous

Lol, i feel you. My calculus studying is boring me so i discovered this place and yet ive made some simple errors. Grrrrrr being tired, having bad eyes and such.

- anonymous

yeah, I stayed up late last night studying, so i'm not my self right now, lol.

- anonymous

did you find this site through paul's online notes???

- anonymous

thank you
one that the teacher gave out
yes
it would be 9+3 =12 and 48 /2=24 and 24/12 =2

- anonymous

Yeah, Studying some triple integrals atm. Great study guide when i barely payed attention all year.

- anonymous

that is how all of my classmates are seeing it

- anonymous

you know what I remember one of my teacher doing one of these problems where a bunch of us go it wrong because we had to stick to the order of operations.

- anonymous

you know, PEMDAS.

- anonymous

@OP You should understand that your teachers question was ambiguous. When you get to higher up math, put stuff in a line as such 48/2*(9+3) means that only 48 is divided by the 2. and not by the 12 as well. You would need brackets surrounding the 2*(9+3) for it to be divided by that as well ie 48/(2*(9+3)). but this is low level math where many things are taught so that it is easy to teach. Later on you will relearn ALOT.

- anonymous

yes...please excuse my dear aunt sally

- anonymous

yeah.

- anonymous

I would agree with finally31, things are more specific later one. You will definitely know what your supposed to do.

- anonymous

Just ask your teacher for more clarification on this.

- myininaya

I'm confused on why everyone is confused about the order of operations. Do the order of operations. so we have 48 divided by 2(9+3)=48 divided by 2(12)=24(12)=288. Just simply follow the order of operations. It isn't ambiguous. After you perform the operation inside the grouping symbols, you do the division and multiplication as it occurs from left to right. So which ever occurs first do that first.
