Isizathu ukuthi mhlawumbe ucabanga ukuthi ufuna obomvu, usebenzisa uyinki obomvu? Oluhlaza okwesibhakabhaka? Usebenzisa uyinki oluhlaza okwesibhakabhaka? Lokho kuyasebenza uma ufuna ukuphrinta leyo mibala emibili kuphela kodwa ucabange ngayo yonke imibala esesithombeni. Ukuze udale yonke leyo mibala awukwazi ukusebenzisa izinkulungwane zemibala kayinki kunalokho udinga ukuxuba imibala eyisisekelo ehlukene ukuze uyithole.
Manje kufanele siqonde umehluko phakathi kwe-additive kanye ne-subtractionumbala.
Umbala owengeziwe uqala ngomnyama, ongenakukhanya, bese wengeza ukukhanya okunemibala ukudala eminye imibala. Yilokhu okwenzeka ezintweni ezikhanya, njengesikrini sakho sekhompyutha noma se-TV. Hamba uyothenga ingilazi yokukhulisa bese ubheka i-TV yakho. Uzobona amabhlogo amancane okukhanya okubomvu, okuluhlaza okwesibhakabhaka nokuluhlaza. Konke kucishiwe = okumnyama. Konke kuvuliwe = Okumhlophe. Amanani ahlukahlukene ento ngayinye = yonke imibala eyisisekelo yothingo. Lokhu kubizwa ngokuthi umbala owengeziwe.
Manje ngephepha, kungani limhlophe? Kungenxa yokuthi ukukhanya kumhlophe futhi iphepha libonakalisa konke. Iphepha elimnyama limnyama ngoba limunca yonke imibala yalowo kukhanya okumhlophe futhi akukho nokukodwa okubonakalayo emehlweni akho.
