Mayelana nalolu hlelo lokusebenza

I-“Mental Arithmetic” iwukuzivocavoca kwezibalo okuguquguqukayo okunezilungiselelo ezivumelana nezimo kakhulu kanye nezibalo ezinemininingwane. Izoba wusizo kubo bobabili abantu abadala kanye nezingane ngoba izibalo zengqondo ziwukuzivocavoca okukhulu kobuchopho kunoma iyiphi iminyaka!


Yini eyenza ukujima kusebenze?
★ Izimpendulo zingakhethwa esikhundleni sokungena ngamadijithi
★ Ngomsebenzi ngamunye oxazululwe ngendlela efanele, amaphuzu anikezwa. Uma uphendula ngokushesha, uzothola amaphuzu ebhonasi ngesivinini


Yini eyenza ukwenza ngendlela oyifisayo kube nezimo?
★ ungakwazi ukuqeqesha umsebenzi owodwa noma eminingana (ukwengeza, ukususa, ukubuyabuyelela, ukuhlukanisa, iziqu)
★ ungasebenzisa izilungiselelo ezijwayelekile zezinombolo (idijithi eyodwa, idijithi ezimbili, njll.), noma ungasetha uhla lwakho lwangokwezifiso
★ ubude besikhathi sokuqeqeshwa bunganqunyelwa: 10, 20, 30, ... imizuzwana engu-120, noma ungadlala inqobo nje uma ufuna
★ inani lemisebenzi linganqunyelwa: 10,15, 20, ... 50, noma ungakwazi ukuxazulula imisebenzi uze ube nesithukuthezi
★ ungakhetha inombolo yezimpendulo: 3, 6, 9, noma ungafaka impendulo ngamadijithi


Zithini izibalo?
Konke ukujima kulondoloziwe. Ungahlala uhlola izilungiselelo zokujima, imisebenzi nezimpendulo zakho. Isibonelo, ungasetha ukujima kwengane yakho bese uhlola imiphumela. Ukujima okungahlukanisiwe kungasuswa. Ukujima okubalulekile kungamakwa ngebhukhimakhi.


Kunezinketho eziningi zokuqeqesha. Nansi eminye imibono:
★ Ukwengeza nokususwa kwezinombolo ezinedijithi eyodwa, ububanzi bomphumela kusuka ku-0 kuye ku-9, izinketho zokuphendula ezi-3, imisebenzi eyi-10, isikhathi esingenamkhawulo
★ Ukwengeza nokususwa kwezinombolo ezinamadijithi amabili, ububanzi bomphumela kusuka ku-10 kuye ku-50, izinketho ezingu-6 zokuphendula, akukho mingcele, qeqesha uze ube nesithukuthezi.
★ ukuhlanganisa nokususa izinombolo ezinamadijithi amabili, izinketho ezingu-6 zokuphendula, imisebenzi eyi-10, ubude besikhathi semizuzwana engu-20
★ ukuphindaphindeka kwezinombolo ezinedijithi eyodwa (ithebula lokuphindaphinda), izinketho ezi-6 zokuphendula, imisebenzi engama-30, isikhathi esingenamkhawulo
★ ithebula lokuphindaphinda, izinketho ezi-6 zezimpendulo, imisebenzi engenamkhawulo, ubude besikhathi semizuzwana engama-60
★ ukuphindaphinda nokuhlukaniswa kwezinombolo ezinamadijithi amabili ngezinombolo ezinedijithi eyodwa, izinketho ezi-6 zokuphendula, imisebenzi engama-50, isikhathi esingenamkhawulo
★ ukuphindaphinda nokuhlukaniswa kwezinombolo ezinamadijithi amathathu ngo-5, akukho mingcele
★ ukususwa kwezinombolo ezinedijithi ezimbili ezingezinhle, izinketho eziyi-9 zokuphendula, imisebenzi engama-20, isikhathi esingenamkhawulo


Okobani?
★ Izingane. Kahle kahle izisekelo ze-arithmetic. Funda ithebula lokuphindaphinda. Kunconywa ukusetha ubuncane bezinketho zempendulo futhi ungakhawuleli ubude besikhathi. Kodwa inani lemisebenzi linganqunywa, isibonelo: ukuxazulula imisebenzi engama-30 yokuhlanganisa nokukhipha.
★ Abafundi nabafundi. Ukuze umkhuba izibalo kwansuku. Imikhawulo yesikhathi ingavulwa, lokhu kufaka ingcindezi futhi kwenza umdlalo ube bukhali. Inombolo yezimpendulo kumele isethwe ku-6, 9 noma i-input ngamadijithi.
★ Abantu abadala abafuna ukuxazulula ngokushesha engqondweni noma bagcine ubuchopho babo busesimweni esihle.


Imibono eyengeziwe kancane yabafundi nabantu abadala.
★ isivinini sesitimela: xazulula imisebenzi eminingi ngangokunokwenzeka ngo-10, 20, ... ect. imizuzwana
★ ukukhuthazela kwesitimela: xazulula imisebenzi eminingi njengoba ufuna ngaphandle komkhawulo wesikhathi
★ ngcono umphumela: xazulula 10, 20, ect. imisebenzi ngokushesha ngangokunokwenzeka, bese uqhathanisa nokujima kwangaphambilini (kusuka kwizibalo)
