6/2(1+2)
It's not (6/2)(1+2), which would be 9. It's 6/2(1+2). You have to do the parentheses first. That makes the expression: 6/2(3). You have to do the 2*3 first, because this is a fraction. It's 6 OVER 2*3. Not 6 over 2, times 3. 2*3 is 6, so now you have 6/6. That equals 1.
Basic math, folks.

Again, false. Its not a fraction. Its 6 ÷ 2 x 3, in order.
I give up attempting to explain this...

Then the expression is faulty. Both answers are correct because the expression does not place parentheses. If 9 is to be correct, you have to place the 6/2 within parentheses, to make (6/2)(1+2). Otherwise, you place the entire problem within parentheses (which you can do to any expression or equation) to make (6/2(1+3)) which, once again is a fraction and the answer will be 1.

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
After the parenthesis read the equation from left to right. If you can read english you get 9 if you read right to left you get 1. The answer to the equation is 9, no further discussion is needed. It doesn't get any simpler than the example shown. If you do not understand I suggest you get a pre-algebra text book, read and practice. Just like in the third grade.
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.

PEMDAS
Parenthesis
Exponents
Multiply
Divide
Add
Subtract
6 / 2(1+2)
1+2 = 3
2*3= 6
6/6 = 1
Seriously, my heart is broken that this has required an entire thread. This is why America is weak.

This next example displays an issue that almost never arises but, when it does, there seems to be no end to the arguing.
Simplify 16 ÷ 2[8 – 3(4 – 2)] + 1.
The general consensus among math people is that "multiplication by juxtaposition" (that is, multiplying by just putting things next to each other, rather than using the "×" sign) indicates that the juxtaposed values must be multiplied together before processing other operations. But not all software is programmed this way, and sometimes teachers view things differently. If in doubt, ask!

Why did you multiply before you divided? That action is inserting parenthesis that arent there. The division should be done first.
