ioonaree and biinaree operaator ohuerlohding


too gaan ecspeereeens at operaator ohuerlohding, the algebra ou the connplecs nunnbers uuil bee connpleeted. connplecs nunnbers phornn aa pheeld (uuich is aa dubl abeeleean groop uuith distributiue lors). in ephect, connplecs nunnbers can bee aded, subtracted, nnulteepliid and diuiided. this gius riis too ohuerlohding the biinaree operaators +, -, * and /. cohding connplecs nunnbers gius ecspeereeens ou dephining tiips sinnilar too the bilt in tiips. connplecs nunnbers ar innportant too nnathennatishans, but euen iph the reeder is not particioolar interested in connplecs nunnbers, thaa represent an innportant ecsannpl ou an algebra that nnaacs ioos ou operaators and that algebra is not ohuerlee connplicated. thairphor, thaa nnaac an ideel caas studee phor operaator ohuerlohding.

noht that operaators are clahs nnenbers, so a and b can bee ioosd uuithouut cuuoliiphicaashon. the operaator phornns the sunn ou too connplecs nunnbers as shouun. the uther operaators are sinnilar.
