the answer is 7 because of bedmas first you divide 6 by 3 which is 2 then subtract 9 by 2 which is 7.
Hi Mr. Isfeld well the anwser is 7!!!! i know this because i guessed! I hope I'm right?

9 subtract 6 divided by 3 = -7 Proof: you have to divide 6 by 3 first(because it said in BEDMAS)which equals to 2. then 2 subtract 9 = -7(is that right???)
The answer is 7 because you divide 6 by 3 first which equals 2-9=7
the answer is actually negative 7 because 6 divided by 3 = 2-9 = negative 7
The Answer is 6.
9 - 6 / 3 ( does not equal) 1 .
Explanation(s) :
First solve it the other way around.Then take the sum, and solve the last following steps to get the answer, which would be 6.
9 - 6 / 3 (doesn't equal) 1.
\ /
9 /2 = (6)
Therefore the answer is 6.
Fix up.
9-6/3 ( doesn't equal) 1 .
First solve it the other way around. Then get the sum, and solve the other steps (Bedmas) to find the answer .
9-6/3(doesn't equal) 1 .
\/
9-2
\/
7.
Therefore 9-6/3 ( doesn't equal) 1, because it equals 7 .
Monica Sousa 7-42 The answer is 7.
When you divide 6*3=2, then 9-2=7
The answer is - 7 because division comes before subtraction in BEDMAS so you have to go 6 divided by 3 and the answer to that is 2. The next question is 2 - 9 and the answer to that is negative 7.
please answer up here everybody
9-6=3
(3^1)x1=3
9 minus 6 divide by 3 does not equal 1 prove it
-7 is the possible answer...(i think)
do we have to answer here
well if we had to answer here...
my answer will be -7..because 6divided by 3 is equals to two then subtract 2 to 9 and will get -7
ok
ok mr.isfeld
9 - (6 ÷ 3) = -7
i got this answer because i used the bedmas thing...

9 minus 6 divided 3 does not equal 1 because of the order of operation BEDMAS.
Order of operation
Brackets
Exponents
Division
Multiplication
Addition
Subtraction
The order of operation goes top to bottom. So first you have to divide 6 and 3 which equals 2 then subtract 9 and 2 which equals 7.
Answer: 7
Not: 1
heres how i got it
9-(6/3)=2
9-2=7 so the answer is not 1 it's 7
I think the answer is -7 because if you use bedmas, division comes before subtraction so
9 - 2(6 divided by 3) = -7
-Ralph 7-72
It's 9 plus 6 divide by 3 = 5!
There that's your proof!

I think the answer is 7 because according to the BEDMAS rule the brackets must go first next the exponents then division then multiplication then addition and subtraction. Since the question is 9 subtracted by six divided by 3, we need to divide 6 and 3 = 2
then we need 9 to be subtracted by 2, so the answer is 7.

Binesi 7-72
the answer is -7 because you have to use bedmas to figure out what part of the question you answer first. So six divided by three = two and when you subtract nine you end up with -7.
dear mr. Isfeld,
i think that the answere is seven because 6 /3 = 2 and 9-2= 7.
room 42, Laura.
the answere is 7 because six divided by 3 is 2 and 9 minus 2 is seven.

Hi Mr. Isfeld.
The question is 9–6÷3≠1.
I agree with you because you should solve the question with parenthesis first, but there's no parenthesis in this question so you should solve multiplication and division first. There's a division in this question so you should divide 6 by 3 equals 2. The second thing you should do is solve the addition and subtraction. There's a subtration in this question so you should subtract 9 by 2 equqls 7.
Thanks.

9-6 divided by 3 is not equal to 1
9-(6 divided by 3)=2,not equal to 1
9-2=7, not equal to 1
1 is not equal to 1
aldrine ang 7-72
9-6 divided by 3 is not equal to 1
9-(6 divided by 3)=2,not equal to 1
9-2=7, not equal to 1
1 is not equal to 1
Because you have to remember that the division comes before subtraction. So you would have to do 6 divided by 3 first, which would equal 2. Then you do the subtraction. Which is 9-2=7.

Hi Mr. Isfeld i got how i found the anwser.....i did 6 divided by 3=2 the i did 9 - 2=7!!!!!
I think it was BEDMAS!!!!!
9-6divided by 3 not 1. the answer is -7 bec. (BEDMAS) I divide 6 by 3 then i got 2 then i minus 2-9then equals -7
hi mr.isfled .. well the answer is 7 becuz first u 6 divided by 3 and the answer is 2 and then u 9-2 the answer is 7 ..

the answer is 7 because you have to use bedmas in bedmas divide is first then its subtract

Charle, Room 42
the answer is 7 because 6/3 = 2 and 9-2 = 7
*you divide first because of bedmas
- John 7-43
Elaine 7-72
The answer is -7, because you use "BEDMAS." But instead of multiplication and addition, you use division and subtraction.
First you divide 6 by 3, thats how you'll get 2. Next, you take away 9 from the 2 which will equal "-7."
by: giuseppe
My answer is 7 because you have to follow the order of operation or also known as BEDMAS. That means 6 divide by 3 is 2 then subtract it from 9 so the difference is 7.
Hi Mr. Isfeld,
My answer is 7, because I follow the order of operation also known as BEDMAS. I divide 6 by 3 and the quotient is 2, then I subtracted it from 9 and the difference is 7 I hope I got the right answer.
by: GIUSEPPE
answer is -7
6 divide by 3 = 2 - 9 = -7
The answer is 7 because of BEDMAS
btw the question is messed up in firefox

By Jerick 7-44
i am positive that the answer is 7 because u have to use that thing Bed something.
i think its -7 because in bedmas divided 6 by 3 = 2 then 2 - 9 = -7
right???mr. isfeld its so hard

Question: 9 minus 6 divided by 3 = 1 does not equal 1
Answer:9 minus 2 = 7

the answer is 7 well because of bedmas.
division first then subtraction right Mr.Isfeld?

The answer is 7 mainly because of
BEDMAS
9 - 6 � 3 = 1 (WRONG)
9 - 6 � 3 = 7 (CORRECT)
9 - (6 � 3) = 7 (HOW TO)
For me place value helps us know the value of numbers and helps us understand the numbers and the number system.

hi! mr.isfeld
haha.. my first answer is in the chat box.. but i'll right here again then..
my answer is 7 beacuse 3 divided by 6 is equal to 2 and 2-9= 7
vanessa 7-42.. ;P
the answer is seven mr.izfeld, because i left out the nine then added 5 and 3 together, which make 8 and i subtracted the one! So the answer will be 7!!!

oh is that a 6? oh i thought that was a 5! well my explination was wrong on the other comment that i posted! ok well i'll do it again!
the answer is seven because i left out the nine and then i divided 6 and 3 so that equals 2, then i subtracted 9 and 2 which equals 7!
marielle c 7-44
Great job, all of you! People who said the answer was 7, -7, 6... Remember, the only wrong answer is no answer. You just learn from your mistakes. Keep it up (:
