Iyini inkinga yokuthuthukisa?
Ezemathematics nesayensi yamakhompyutha, inkinga yokuthuthukisa ngokuvamile inkinga yokusesha lapho isixazululo esingcono kakhulu ukuthola phakathi kwazo zonke izixazululo ezingenzeka. Inkinga yokuthuthukisa ingahlukaniswa njengokuqhubekayo noma okuhlukile kuye ngohlobo lwezinto eziguquguqukayo. Enkingeni yokuthuthukisa okungaqondakali, izinto eziguquguqukayo zihlukanisiwe futhi zingabalwa. Ngokuphambene nalokho, iziguquguquki eziqhubekayo zifaka phakathi amanani angenakubalwa ngokungapheli, isibonelo, okuguquguqukayo ebangeni elingelona elingenalutho lezinombolo zangempela.  Ngokuya ngenani lemisebenzi enenjongo, inkinga yokuthuthukisa ihlukaniswa njengenhloso eyodwa noma eminingi. Inkinga yokuthuthukisa enomgomo owodwa ihilela umsebenzi owodwa kuphela wokuthuthukisa. Ngakolunye uhlangothi, inhloso enezinhloso eziningi ibheka izinhloso ezimbili noma ngaphezulu ngasikhathi sinye, okusho ukuthi kufanele kubhekwe ukusebenzisana phakathi kwezinhloso.
