Math: 6÷2(1+2) = ?

6 + 3 = 9
(6÷2)2 + (6÷2)1 = 9
(6÷2)(2+1) = 9

---------------
6 ÷ 6 = 1
6 ÷ (4+2) = 1
6 ÷ 2(2+1) = 1

I know no rule that states a number and another between parenthesis should be multiplied or added.

a(b+c) = (ab + ac)
If c = 0, we have:

a(b + 0) = (ab + 0) = (ab)

Called distributive property along with the addition identity.

The division symbol is not to be construed as necessitating a numerator/denominator relationship.

The parenthesis and order of operations supersedes everything else.

So, 9.

the correct answer is 9

parenthesis first and then it goes from left to right

6/2 = 3
1+2 = 3
3*3 =9

First:
Today, parentheses or brackets are used to explicitly denote precedence by grouping parts of an expression that should be evaluated first.
Then:
The order of operations used throughout mathematics, science, technology and many computer programming languages is expressed here:[2]
exponents and roots
multiplication and division
addition and subtraction
This means that if a mathematical expression is preceded by one operator and followed by another, the operator higher on the list should be applied first.

Mnemonics (like PEDMAS) may be misleading ...especially if the user is not aware that multiplication and division are of equal precedence, as are addition and subtraction.

The correct answer is 9.



Arithmetic Order of Operations:

Rule 1: First perform any calculations inside parentheses.

Rule 2: Next perform all multiplications and divisions, working from left to right.

Rule 3: Lastly, perform all additions and subtractions, working from left to right.

This thread is still going!?*^)$ WOW :o

the important thing is that you tried! not if you get the right answer!!!!1

6/2= 3
(1+2) multiply brackets X first calculation

3 X 3 =9

No other answer is correct.
You always always work left to right on math problems.

Parenthesis - (1+2) = 3
Exponents - None
Multiply - 2(3) = 6
Division - 6÷6 = 1
Addition - Equation is already done
Subtraction - Equation is already done

OP even mentioned 1 in bold in the original post.

9 you friggin herpderps

3(3)=9

Yes, its that simple.

wow

9. You bunch of boneheads!

9



thank you

Still 1

1

As if the OP was somehow the authority on the question.

The equation is poorly written so it could be 9 or 1 but here:

6÷(2(1+2))=1

(6÷2)(1+2)=9

Trust me i'm a math major

1

The fact that so many of you are so wrong is hilarious.

U must show your work

6/2(1+2)=
6/2(3)=
3(3)= 9

No that is wrong

6 is the numerator!

9.


BEDMAS, bitches.

I can't believe how complicated some are making it out to be.

Grade 7 math FTW.

Multiply or Divide before you Add or Subtract. Example:

Otherwise just go left to right. Example:

30 ÷ 5 × 3 = 6 × 3 = 18 yes


30 ÷ 5 × 3 = 30 ÷ 15 = 2 no

(wrong)

Divide and Multiply rank equally (and go left to right).

Ummm it's 1, he gave you the answer in the original post...

No, it's not.

Use BEDMAS.


Or, just copy and paste the equation into google. I just did to see if it would work, for fun... since I already knew the answer was 9 from elementary school math class.
