Kungani abanye bekholelwa ukuthi izinkinga zokwenza okuhle okuqhubekayo kungase kube lula ukuzixazulula kunezinkinga zokwenza okuhle ezihlukanisiwe?
Abanye bakholelwa ukuthi izinkinga zokwenza ngcono okuqhubekayo kungenzeka kube lula ukuzixazulula kunezingalingani zazo ezihlukanisiwe, ngenxa yokuthamba kwemisebenzi enenhloso, evumela ukusetshenziswa kwamasu we-calculus. Ngokuvamile, amasu e-calculus asho ukusebenzisa ulwazi oluhlosiwe kanye nemingcele endaweni ethile x, ukuthola ulwazi mayelana nokuziphatha komsebenzi ohlosiwe kuwo wonke amaphuzu aseduze no-x. Ulwazi oluvelayo lusetshenziselwa ukuqondisa indlela yokusesha. Ngokuphambene nalokho, izinkinga zokwenza ngcono okuhlanganisiwe ngezinga elithile kunzima ukuzixazulula kunezo eziqhubekayo. Lokhu kungenxa yokuthi ukuziphatha komgomo kanye nemingcele kungashintsha kakhulu njengoba sisuka kwelinye iphuzu elingenzeka siye kwelinye, ngisho noma la maphuzu amabili esondelene ngokwemigomo ethile. Ngakho-ke ngokuvamile akunakwenzeka ukukhipha ulwazi ngamaphuzu angomakhelwane kulelo elikhona.
