Umshini wokulinganisa ubhontshisi kanye nomshini wokugreda ongawusebenzisa kubhontshisi, ubhontshisi wezinso, ubhontshisi wesoya, ubhontshisi, okusanhlamvu.amakinati kanye nembewu yesame.
Lo mshini wokulinganisa ubhontshisi kanye nomshini wokugreda owokwehlukanisa okusanhlamvu, imbewu nobhontshisi ngosayizi ohlukene.Kudingeka kuphela ukushintsha usayizi ohlukene wezisefo zensimbi engagqwali.
Ngaleso sikhathi ingasusa ukungcola kosayizi omncane kanye nokungcola okukhulu nakakhulu, Kukhona izingqimba ezi-4 nezingqimba ezi-5 kanye nomshini wokulinganisa izendlalelo ezingu-8 ongawukhetha.
