6÷2(1+2)=?

The answer is 9. Use my method above:

Please Excuse My Dear Aunt Sally

Please -- Parenthesis
Excuse -- Exponents
My ------- Multiplication
Dear ----- Division
Aunt ----- Addition
Sally ----- Subtraction


6÷2(1+2)=

You do the Parenthesis first, so

6÷2(3)

There are no Exponents or Multiplication just yet, so 6÷2=3:

3(3)

The above is the same as 3x3, which = 9.

Your answer is 9.

Here you go... here is the answer. Hope we can all stop arguing the obvious...

6/2(2+1)
Parenthesis
Exponentials
Multiplication
Division
Addition
Subtraction...

you do not DIVIDE 6/2 first..
U ADD WHATS IN PARENTHESIS, THEN MULTIPLY BY 2...

This is 3rd grade my friends.. what schools are you going to??

6 divided by [ 2 * (2+1) = 6 ] TOTALS TO 6 divided 6 which in turn equal 1...

thanks

Wow, u sure sound sure of yourself... even when you are wrong. True shill. go back to school.

Anyone saying the answer is 9 isn't using the order of operations.

6÷2(1+2)

1+2 = 3
3 x 2 = 6
6/6 = 1

As for the BEDMAS vs. PEMDAS thing, they're the same damn thing. Brackets and parenthesis are the same thing, and division and multiplificaton are interchangeable; you just do whatever comes first. Same thing for addition and subtraction.

Just remember to use your order of operations.

Order of operations: BEDMAS

Brackets
Exponents
Division
Multiplication
Addition
Subtraction

1+2=3
2x3=6
6/6=1

edit on 1-5-2011 by snowspirit because: spelling

if division is before multiplication in operation order wouldn't it be

1+2=3
6/2=3
3x3=9?

I was always taught that the multiplication and division are interchangeable, but that the number sitting right outside of the brackets (the 2) is somehow always used next after the brackets - I guess like it's part of the bracketed part of the equation

The "Please Excuse My Dear Aunt Sally" from Bonez post actually makes more sense for remembering.

Google decares the answer as 9

Google Answer

I would think that Google has the right answer.

You sir must use the order of operations.

For the answer to be one it must look like this:
6÷[2(1+2)]

There is so much math fail in this thread.
/facepalm

6/(2(1+2)) = 1

I stand corrected

The answer is 1.

Working:

6÷2(1+2)

= 6 ÷ 2(3)

= 6 ÷ 6

= 1

or alternately,

6÷2(1+2)

= 6 ÷ (2 + 4)

= 1

Ok...Do Parentheses first...
[color=ff0000](1+2[color=ff0000]) = [color=00ff00]3

Then 6÷2...
[color=ff0000]6÷[color=ff0000]2 = [color=00ff00]3

Since there is no sign between 6÷2 and (1+2) you multiply the sums...

[color=ff0000]3×[color=ff0000]3= [color=00ff00]9

The answer is 9

Answer is not 9 guys, sorry, google is wrong

9

Wow

Faith in our system of education is dwindling.

This... seems not enough information was given by OP in order to determine the correct answer. Stop arguing.. both sides are correct:

‎6÷2(1+2)
6÷2(3)
6÷6 = 1
2(3) is P in PEDMAS

OMFG.....how is this generating controversy....its 9....WTF....this is scaring me....I have heard of the schooling systems failing to teach, but seriously BEDMAS or PEMDAS...its 9...as said it flows from left to right in math...JUST GET YOUR HEAD AROUND IT...stop arguing non math to make it 1....OMG enough people have chimed in....the 6/2 is outside the bracket...and the 2+1 is inside...they are to be done separatly...then multiplied together....please just stop this thread here....its really reflecting poorly on the populace...3(3)=9 ok?

However I must say I may be as wrong as everyone else....we are all right?? everyone happy....just hope you get a teacher that agrees with you on your test lol...

This is not arguing, this is an educational discussion on maths.
