Math: 6÷2(1+2) = ?

6/2 =3

1+2=3

3x3=9

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.

Parentheses first, 1 + 2 = 3

Then 6 ÷ 2 = 3

Then, since the equation is division, 3 ÷ 3 = 1

That's from basic math that I learned like 40 years ago, so I hope I'm still right.

SHILLS! IT'S 1!

answer is 1

Step1: 2(1+2) = 6
step2: 6/6 = 1

correction answer is 1

6
- * (1+2)
2

= 3(1+2)

= 3+6

= 9

1.. i did it in like 3 seconds before i even clicked on the thread.. what is it supposed to be? math for retards?

the order of operations says to do multiplication and division at the same stage, but from left to right, with parenthesis first


6÷2(1+2) = ?
parenthesis
6÷2(3) = ?
leftmost division
3(3) = ?
then just multiplication left
3(3) = 9

Christ why are we doing this again? It's the same problem as before with different numbers.

thanks for the reminder! XD

So far it looks like "9" is the dominant answer.

I'll check in later, compile all the categories of answers, and make a viewable .pdf spreadsheet.

9 of course

It's it BIDMAS (brackets, indices, division, then multiplication, addition, subtraction)

So brackets first

6/2(3)

Then division

3(3)

Then multiplication

9

Answer is 1!
6/2(1+2)
6/2(3)
6/6

1

ditto

HA. NOBODY knows math! Why do they even bother to teach it? lol

1 + 2 = 3
then we don't have priority parenthesis and priority of * and / are the same but calculations are done from left to right. So finally

6 / 2 * 3 = 3 * 3 = 9

What's the problem?

Are American really that poorly educated? It is a math problem for 7 years old in Russia and China. We did much more complex equations when we were first grader. Goodness. I am even afraid to ask how much will be (x / sin (x^2))' | x=pi/2 (simple high school math problem in Russia)

6/2(1+2)=9

9.

First solve in parenthesis
6/2(1+2)
6/2(3)

Then solve, LEFT TO RIGHT, Division and multiplication have the same "ranking".
6/2 (3)
3(3)
9

6 (1+2)
-
2




= 9


Simple

The answer is 1 those of you who got anything else just failed my Math class!

9.....nine is the number and the number is nine. Ten thou shall not go'ith, for that is to far....

I'd also like to see the percentage by country who answer "1", or "9".

Good call.

Does anyone else's gut hurt from laughing at some of the proposed answers? Going to need some PK's soon if this continues.

i posted something similar on FB a couple weeks back. absolutely amazed at the answers... :(

6 does not go into 2. Answer then is 3.

It's fucking 9

NINE

Not 1

morans

Ok answers either 1 or 9, the one australian present guessed 1 therefore without a doubt it must be 9!

HAve you got sumthin easier?
