I don't see why you are getting an unsimplified result. If you enter ((1+ 2 I) - (43 - 4 I)) into an input cell it does evaluate as expected. Perhaps you need to show some of the steps leading to this unsimplified result? ____________________________________________________________________ Paul Abbott Phone: +61-8-9380-2734 Department of Physics Fax: +61-8-9380-1014 The University of Western Australia Nedlands WA 6907 mailto:paul at physics.uwa.edu.au AUSTRALIA http://physics.uwa.edu.au/~paul God IS a weakly left-handed dice player ____________________________________________________________________
