48÷2(9+3) = ???

How can you distribute a number on to a number that is called multiplication ! You guys are saying that 2(12) is different than 2*12

A simple one when you try to find GDP givin disposable income and spending habits of people.  Or when you are trying to find the DI such as (I-t) and then you have a percentage such as .6 as 60% of the DI is used to spend on something particular.  so a formula would be based something along the lines of Y=C+.6(I-t) where I-t is DI.  You'd distribute the .6 and thus get an answer. 

I don't know, in my upper level Macro econ and Math for economist classes we were doing things like this.

By distributing to the parenthesis you break the order. If the problem was 48/(2(9+3)) then the answer would eventually be 2. The 48 being first in order gives it the right to divide by 2.

you can't simplify the terms in the parentheses, so you move on to the next thing in the order of operations.

PEMDAS

multiplication comes before addition, so you multiply (or distribute) the .6 by the terms in the parenthesis, then add/subtract the three terms to get your answer...

i don't see any similarities between this problem and the original problem. it's already been stated/cited multiple times that the distributive property only applies to variables, so this isn't anything new... 

EDIT: if you had actual number values for l, t, and C there would be no need to 'distribute' when solving the problem.

No because you're distributing which takes preference.

Hey, you're entitled to your opinion.  However, I know that my professors taught us differently and I believe them over some random NTer.  Especially since it was multiple professors not just one.

distributing is a product of pemdas, its not some new rule, distributing only applies when theres an addition, subtraction, or nothing in front of the outside multiplier, in this case theres a division...  PEMD>AS
