I’m a math professor, and my view is that although the standard convention, if applied precisely and rigorously, does give an unambiguous procedure to follow, nobody, and that includes professional mathematicians, would ever write a formula like this. This is mostly because, after about 3rd grade, none of us ever use the division symbol ever again.

6/2(1+2)
= 6 / (2 * 1 + 2 * 2)
= 6 / (2 + 4)
= 6/ 6
= 1
Apparently. But It's nine.

or
Parentheses, Exponent, Multiplication, Division, Addition, Subtraction....... That is the order in which you do equations....
6/2(1+2)=9
In kiddie terms...
1+2 = 3
so it's 6/2(3) or Six Secondths times Three
6/2 = 3... Yes because 6/2 is 6 divided by two......
so it's
3(3)=9
3 times 3 equals 9
I cannot beleive such a simple equation needed an entire thread to itself... Can we try a harder one now?edit on 24-5-2011 by DaMod because: (no reason given)
