Question

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

Answer 1

order of operations

Answer 2

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

Answer 3

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))

Answer 4

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

Answer 5

thats not how it looks....it looks like this 48÷2 (9+3) = ?

Answer 6

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

Answer 7

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

Answer 8

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

Answer 9

That would be 264

Answer 10

are your classmates getting two????

Answer 11

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

Answer 12

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

Answer 13

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

Answer 14

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

Answer 15

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.

Answer 16

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

Answer 17

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

Answer 18

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

Answer 19

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

Answer 20

that is how all of my classmates are seeing it

Answer 21

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.

Answer 22

you know, PEMDAS.

Answer 23

@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.

Answer 24

yes...please excuse my dear aunt sally

Answer 25

yeah.

Answer 26

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

Answer 27

Just ask your teacher for more clarification on this.

Answer 28

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.
