I like the shirt... but i would much rather the bumper sticker, since i took the time to alienate 45% of a local forum who believed the answer was 288.
I will show up to the next meet with that sticker on my car, modified to replace the "??" with "2."

The answer is 288. It's also 2.

You can see Texas Instruments updated their TI-85 when they found it couldn't get this answer right. The clearly superior TI-86 has the right answer. lol

haha this is just getting funny now lol
I'd rather have the bumper sticker, except I still want the "my 48/2(9+3) cents" Hey, I accepted the answer because I learndid something on all this.
Ben, i'm still going to donkey punch you in the nads

All I know is if I did the order of operations differently, I would have never have made it through engineering school. Maybe my whole college does it differently; (not a joke or a jab, just different places do things differently.)
(My TI-89 give me 288 and adds in the ambigious multiplication sign.)

9 pages! impressive discourse, too. Read all the posts, which has lead to the following question: How do structural engineers clearly(!) communicate to each other so the above does not occur? I'm thinking more along the lines of clear communication to avoid failure of structural analysis? Are there hard and fast rules to that math?

48÷2(9+3) =
48÷2(12)=
48÷24= 2
2
Standard order of operations problem.

If I were writing it so that it wouldn't be misunderstood, I'd write
48
2(9+3)or
48÷[2(9+3)]

According to the prof, it's 288.

In reply to DILYSI Dave:
No you'd write it (48/2)(9+3)
In reply to triumph5:
that divided sign is never used in real math.

I'd like to see the age of the person and their answer: Me: 29, 288. respectively.

How come you get to arbitrarily assign parantheses on a whim, breaking up an expression, but cry foul when we use Implied Grouping Laws?
I'm 25, answer is 2.
Girlfriend is 21, answer is 2. -

MS Excel and SQL Server both answer your question with 288. One or both of these products probably had something to do with your paycheck, and also fits the rule of Inside the brackets first, then multiplication and division left to right then addition and subtraction left to right. There's more to the rule, like logs, exponentials, etc., but you don't have any of that in your equation.
Your girlfriend good at math, is she? Pics or it didn't happen.
That's a pretty funny pic, Eddie. I bet a HP gets it right, though.
