Haha, I don't think he meant 2 factorial, I think he was just exclaiming that it was 2.
But the original equation is not written like that if it was it would be
I was wondering where you got this question from. Just got this on my feed today and smiled when i saw it.
I still say the answer's 288 tho :X
Guys, the order of operation is this.
2. Exponents or Radicals.
3. Working from left to right, multiplication and division.
4. Working from left to right, addition and subtraction.
Just watch out and keep in mind , from left to right for multiplication, division, addition and subtraction.
@Moorey: That's correct. This is the same equation with one extra parentheses that changed the final results.
48/2(9+3) = 288
48 / (2(9+3)) = 2
Those two, (48/2)*(9+3) and 48/2*(9+3) are the same, but they are totally different from this one 48 /(2*(9+3)).
Just type them in a excel sheet or a programming language to check the results.
in old solution and theory,they explain that multiplication should be 1st solved then division,but a new theory and solution came up with divison 1st before multiplication,and they're both ok to co-exist?that's not right...

And like I have said..
48/2(9x+3x) or 48/2x(9+3) would lead to 48/24x, thusly by general rule of thumb the same has to be true for 48/2(9+3)
Because the (9+3) is tied to the 2 not 48/2 which some people think.
