Simple, do the work in the parentheses first....9+3=12........then you would work left to right with the remaining problem...........(48/2)*12= 24*12=288
wwwwong way....left to right after the parentheses.
After checking various websites NOONE can agree IF the correct answer is 2 OR 288.......
I remembered enough to do the mathematic operation in parenthesis first but It's been decades since I took Differential and Integral Calculus....let alone Algebra.
I've asked Math PhDs, Math Masters, and dozens of engineers.
Only three people said 288 (my 6th grade daughter, her teacher, and this chick at work with a masters in math). All the engineers, the math PhD said 2. (I said 2 myself.)
Think about that. Think about sitting around a conference room table at a technical meeting and a bunch of America's best and brightest immediately think the answer is 2. Think about potentially bad designs based on this very common yet simple error. Mind Boggling.
Almost everyone sees the division sign as separating a numerator of 48 and a denominator of the product of 2 and 12. But that's not what that equation translates to.

Google, Matlab, and Excel will all provide 288.
Then I'm in good company....LOL.....
I can see where the 288 comes from but it's been too long since my Algebra days. In my mind the division is implied??????
Wow, I hope those of you that answered 2 were kidding.
