SUMMARY
The discussion centers on defining a case function in Mathematica using the 'Piecewise' function. User Omri inquires about a convenient method to express a piecewise function, specifically for the function y(x) that returns x for positive values and -x for negative values. Another user confirms that the correct implementation is y[x_]:=Piecewise[{{x,x>0},{-x,x<0}}], which effectively addresses the query. This solution is confirmed as helpful for users seeking to implement conditional expressions in Mathematica.
