Integrate[Abs[x], x, Assumptions -> Element[x, Reals]]

Piecewise[{{-(x^2/2), x <= 0}}, x^2/2]

=============
On my Ti calculater |x| is easily integrated to |x|*x/2, but when I type Integrate[Abs[x],x] in mathematica, it seams like it can't find the solution.
Is there anything I'll have to do, to make mathematica find the solution?
