I do not mind the way it is in SMath, but I know from my experience as a teacher that this is a standard mistake many students make.Regards,Radovan When Sisyphus climbed to the top of a hill, they said: "Wrong boulder!"

I am not quite sure why Mathcad used it (or most likely - I forgot why) Regards,Radovan When Sisyphus climbed to the top of a hill, they said: "Wrong boulder!"
