Question

I am answering a problem and I get 9. My friend says the answer is 1. I believe I am right because I am using PEMDAS. The problem is: 6/2(1+2)=?
This is, well, my friend is driving me insane. Please help.

Answer 1

i get 1

Answer 2

you follow pemdas so you do parenthesis first so 2 + 1 = 3
then you do multiplication 3(2) = 6
then division 6/6 = 1

Answer 3

probably because your friend is answering this
\[\frac{ 6 }{2 }(2+1)\]
and you're answering this
\[\frac{ 6 }{2(2+1)}\]

Answer 4

I also get 9; but I would let someone else try to explain before me since I'm usually incorrect

Answer 5

or vice-versa

Answer 6

First you do the brackets and then you go from left to right.

So 6/2*3 = 9

Answer 7

Jayz657 I think you did PEMDAS wrong.

Answer 8

It depends on how the problem is perceived. \[6\div2\times(2+1)=9\]but\[\frac{ 6 }{ 2(2+1) }=1\]

Answer 9

it depends on where the (2+1) is at if its on the numerator then its 9 and if its on the denominator is 1

Answer 10

Exactly what I said. lol

Answer 11

lol yea sorry didnt see it, was probably typing when you said that haha

Answer 12

There is no fraction. The problem reads: 6 divided by 2(1+2)=? With PEMDAS I did the parenthesis (1+2)=3. Then using PEMDAS I divided 6 by 2 and got 3. Then, 3 x 3 = 9

Answer 13

You are all forgetting the rule that says we go from left to right when solving equations, only if there are operations that come first, such as multiplication, division, brackets.. we switch the order.

Here you do do brackets first, as always, so you get 6/2*(1+2) = 6/2*3 = (What now? You use the "Go from left to right rule.") And you get the obvious... 3*3 = 9.

Answer 14

agree, the answer is 9

Answer 15

So, my friend getting an answer of 1 is wrong because she is not using PEMDAS?

Answer 16

ok w/e instead of just getting all confused with pemdas, factor in the 6/2 into the parenthesis

6/2 + 6/2(2)
3 + 6 = 9 there

Answer 17

yea, if ur question is
6 : 2 x (3+1)
really, division and multiplication as strong as of both
but, first operation will be precedence it.

Answer 18

i would go with 9

Answer 19

\[6\div2\left( 1+2 \right)\]

Answer 20

Thanks! I'm going with 9. My friend is sticking with 1. She's stubborn.

Answer 21

oh, sorry... (1+2) i mean :)
