I wasn't thinking of the calculator, and how it automatically respects the order of operations. You're certainly right.
One of the problems of the keyboard is that, when you write a fraction, you don't get the choice of expressing it with a horizontal bar to separate the numerator and the denominator, instead of the diagonal virgule (/). So, writing something like 2x/1+x can't be expressed in the unambiguous way that the horizontal bar permits.
So, 2x/(1+x) it is!
