48/2(9+3)
=24(12)
=288
48/2(9+3)
=24/12= 2
Or 24 × 1/12= 2!
While, 2!=2*1=2, if you made this same mistake if were like 4 ie. 4!=4*3*2*1=/=4. you would run into some problems...
Haha, I don't think he meant 2 factorial, I think he was just exclaiming that it was 2.
the only way it would be 288 is if it was written like this
48
--*(9+3)
2
But the original equation is not written like that if it was it would be
(48/2)(9+3)
Guys, the order of operation is this.
1. Parentheses.
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
@DABhand
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.
