288. Is this still being discussed.
Where is my picture that talks about intelligent people always being less sure about what they do than unintelligent people?

Plug this in a cell in Excel and tell me what you get:
=48/2*(9+3)
288
=48/2*(9+3)
288

I'll make you a deal. Show me anywhere in the AISC SCM or ACI 318, or NDS where the ÷ symbol is used, and I will tell you a project around New Orleans that I have worked on. The problem is written terribly, hence 8+ pages of discussion.

That giant calculator got an actual division symbol on it or does it only have the "/" Evidently it can make a difference and so can "implied" multiplication.

I would think he is using the divide symbol to keep all in one line. That would be cleaner than x/(y(a+b)). People are making a leap they shouldn't unless knowing he meant it that way. If he was doing it that way it is 2. As written it is 288. This should be an example of why math should be written precisely.

I get how you come up with that number.
48x.5x(9+3)=288
To me it comes down to how you read the ÷ symbol. It's either
(48 ÷2)x(9+3)
Or
48 ÷(2(9+3))
One gives you 288 the other 2.
Again the ÷ is ambiguous and there's a reason you won't see it past 8th grade. Also a reason you'll never find it in any industry wide engineering manual.

48÷2(9+3) simplifies to 48÷2×12.
48÷2×12 is the exact same as (48/1)x(1/2)x(12/1)
Which is 48x.5x12.
You just changed my mind.

(48 / 2) x (9 + 3)
That's the same as 48 / 2 x (9 + 3).

It's a redundant parenthesis to clarify the difference in how people read it. The parenthesis doesn't alter the problem in the slightest.
This thread is why textbooks write any equations with division in them as fractions.

But are you entering "/" instead of a division sign? That's the only reason for any debate.
Well, you're arguing the wrong side of that. Using ÷, the answer should be 288. PEMDAS doesn't discriminate, and MD are equal.
However, if / then its
48
____
2(9+3)
That's 2 since everything in the denominator should be worked first.
