I understand that in some instances that the multiplication and division functions are interchangeable.
For example:
(24/4*6)
becomes
(6*6)
becomes
36
However in the original asked equation, 48÷2(9+3)
You DO NOT divide the 48 by 2 and then multiply it by 12! The equation to the right of the division sign commands your attention first because of the parenthesis component. Think of it this way, 2(9+3) is basically like writing the number 24, in that it is a whole number and you can't just part out a piece of it.
You are absolutely right however in that our school systems must be in sorry shape if people like you cannot do 8th grade math.
There's two issues here.
First, you sidetracked from the fact that mentioned that PEMDAS indicates that multiplication comes before division. PEMDAS does no such thing. You are poorly educated on what PEMDAS means. That's all I was pointing out.
You totally missed my point about how if one understands math, understanding PEMDAS should not be trivial. I can go on forever about how poorly math is taught in our schools. Just look at how few people understand what number systems are.
Second, you conveniently ignored the part where I specified that the issue has nothing to do with the original problem. So I'm not going to really comment on that since there's already 28 pages of nonsense discussing it.

Oh God!!! Nightmares really DO come true!!! A whole thread devoted to the solution of ONE algebra problem.... AHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHH!!!!!!!!!!!!!!! !!!!!!!!!!!!!!!!
I have been of the opinion that when it comes to letters and numbers- never the twain should meet.
You have the power to put this thread out of its misery. DO IT!
Hey, as long as people want to discuss it.

In the realm of Wrong Math, sure. But in the real world, following the simple rules of PEMDAS brings the answer of 288.
if
a=48
b=2
c=(9+3)
The equation is:
a÷b*c
or
a*(1/b)*c
To get the answer of 2, the equation would need to be written:
a÷(b*c)
or, in its original numeric form:
48÷(2(9+3))
48÷(2(9+3))≠48÷2(9+3)
