*. therefore the problem must be solved as 62(1+2) NOT 6 (over) 2(1+2) we do the parentheses first, so 62(3), the parentheses are now no longer relevant, because the number inside is in it's simplest form. Every single number has implied parentheses around it.
62(3)
(6) (2)(3)
62*3,
or even converting the division to multiplication by a reciprocal (a legal math move)
(6)(1 (over) 2)(3)
are all correct ways to write this problem and mean exactly the same thing. Using pemdas, where md and as are interchangeable, we work from left to right, so (3)(3) or
3*3= 9


Question? For the teacher
Doesn't 6 divided by 2*3 = 6/6 that equals 1????

And the same for
(6)(1)/(2)(3)=6/6=1

Hopefully some of my students see this so I can stop answering this question.

Sorry - never a great student here but I never minded asking
The questions. Thanks

Correction parenthesis first then because Division and Multiplication holds same rank, its left to right. Its the fact this problem is written in a way just to cause this confusion. It caught me.

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

wow sounds like a bunch of algebra and pre-algebra level mistakes pemdas doesnt work here because you have to distrbute first 6/2(1+2) SO IF YOU KNOW ANY MATH YOU KNOW TO DISTRUBUTE THE 2 INTO THE PARENTHESIS 2*(1+2)=2+4=6 so in turn the expression looks like 6/6 and the answer is 1

I think if the answer were 1, the problem would be written like this

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

Haha, right. She says the order of operation is parenthesis, exponents, multiplication/division (in order they appear) and addition/subtraction (in order they appear).

I asked my 8th grade daughter and she says 9. I showed her how people are getting 1 and she says thats wrong. In order of precedence, parenthesis first and since multiplication and division have the same ranking it is done from left to right. I agree with her 100%.

9 all day
