What if I wrote it as
Z ÷ (Xa + Xb)
tell me what this equation is once the X is factored out of the parenthesis
48÷2(9+3) = ???

C'mon, after 100+ pages it should be clear that the answer is 288 to the problem as written. All the people getting 2 are adding a set of parentheses that aren't there in the first place.

So we are back to multiplying before dividing?Originally Posted by do work son

Team 2 right now:
Trying to bring everything home but failing so miserably.
the reason you do PEMDAS is to simplify all the terms, so to simplify 2(9+3) you are multiplying to satisfy the parenthesis (the first step of pemdas) even if you add the inside first, the next step would be to multiply the 2 and (12) to simplify and get rid of the parenthesis
you guys literally go full circle with your excuses

No it isn't. PEMDAS is used to solve the problem. Parentheses, the first step, is to solve what is inside. Then you do division, and then multiplication.Originally Posted by do work son

2 and (12) exist because parentheses had to be used to solve 9+3 first. After that, the intended purpose of them has been satisfied. That is why we say 2(12) is the same as 2*12. No action must be taken within the parentheses. Division occurs first, then multiplication.
You don't have to "get rid" of the parentheses. You have to simplify what is within them. You get rid of them but solving the problem according to the order of operations.

Yeah my bad, it actually does relate to the problem. But if you do what you did you end up with 24/1(9+3)
See how from here you now follow the order of operations rule. So you go from left to right since multiplication and division are of the same rank.
So you would do 24/1 = 24
24(12) = 288

I studied to become and Pre-school-4th (Generalist) Grade teacher. At some point in this lifetime I plan on actually getting in the classroomOriginally Posted by dmxgod
..nice ignorant statement..but spend a week in the life of a teacher..try teaching Math to students with disabilities/at risk youth/students who are unmotivated/and lack support..hell try teaching all the core subject areas to students like I mentioned..Originally Posted by usainboltisfast
Its a damn shame what the american education system has turned into if teachers are saying this
..
so I would never make light of how hard a teachers job is especially a SPED teacher or a middle school teacher, but the fact is that teaching
PEMDAS (with multiplication taking priority over Division) is just incorrect.

I don't even know what you are asking me to do, and that is not an equation.
I addressed that all, Z ÷ (Xa + Xb) is the same thing which I quoted...
Just read what I quoted, it will explain exactly what I wanted to say.

Like my man Put in Work says remove the division symbol and turn it into a multiplication problem by writing the reciprocal
so
the reciprocal of 48 / 2(9+3) = 48/1 * 1(2(9+3) = 48 * (1/12) = 2

Lol wow. You guys stay changing the problem as much as you can.
"Yeah let's find the reciprocal, ignore order of operations, and throw a whole bunch of parentheses in there so we can show em how we got 2!"
