Hi, Together will do the trick: Together [(x+y/z)] hope this helps, Daniel TuesdayShopping wrote: > Given "(x + y/z)" as input, how do I get the same expression in the form of "(xz+ y)/z". > > Note that the input form may not always have 2 terms. It may be arbitrarily long or may not be in any standard form. It may be like "x+y", or "x + y + (2*w)/z - p/3 +10", or "c", or "x/2" . . . .All that can be assumed about the input is that they are all polynomials bound together with the 5 operators (+, -, *, / and ^), and that whatever the output is, the denominator can be assumed to be not equal to 0. > > Thanks a lot. > -- Daniel Huber Metrohm Ltd.
