Ulwazi olutholakala ezifundweni ze-algebra ne-geometry empilweni abantu basebenzisa ngokungajwayelekile kakhulu. Ikhono eliyigugu kakhulu nelingadingeka elihambisana nezibalo yikhono lokuzibala ngokushesha engqondweni, ngakho-ke kuzuzisa ukuthola indlela yokufunda ngayo. Ekuphileni okuvamile, lokhu kukuvumela ukuthi ubale ngokushesha ushintsho, ubale isikhathi, njll.
Kungcono ukuthuthukisa amakhono kusukela ebuntwaneni, lapho ubuchopho bufunda ulwazi ngokushesha kakhulu. Kunezinqubo eziningana eziphumelelayo abantu abaningi abasebenzisa.
Indlela yokufunda ukubala masinyane engqondweni?
Ukufeza imiphumela emihle, kubalulekile ukuqhuba ukuqeqeshwa njalo. Ngemuva kokufeza imigomo ethile, kubalulekile ukucindezela lo msebenzi. Okubaluleke kakhulu ngamakhono omuntu, okungukuthi, ikhono lokugcina izinto eziningana enkumbulweni futhi ugxile ukunakwa. Impumelelo enkulu ingatholakala ngabantu abanombono wezibalo. Ukuze ufunde ngokushesha ukubala, udinga ukwazi ithebula lokubuyabuyelela kahle.
Izindlela ezidume kakhulu zokubala:
- Sizobona ukuthi singakwazi kanjani ukubala ngokushesha izinombolo ezimbili ezinamadijithi engqondweni, uma ufuna ukuphindaphindeka ngo-11. Ukuze uqonde le nqubo, ake sibheke isibonelo esisodwa: 13 phinda ngo-11. Inkinga yileyo phakathi kwezinombolo 1 no-3 udinga ukufaka inani labo, okungu-4. Ngenxa yalokho, kuvela ukuthi 13x11 = 143. Uma isibalo samadijithi sinikeza inombolo yamadijithi amabili, isibonelo, uma ukwanda ngo-69 ngu-69, bese u-6 + 9 = 15, khona-ke udinga kuphela ukufaka idijithi yesibili, okungukuthi, 5, bese ufaka 1 kudijithi yokuqala ye-multiplier. Ngenxa yalokho, uthola 69x11 = 759. Kukhona enye indlela yokwandisa inombolo ngo-11. Okokuqala, phindaphinda ngo-10, bese ufaka inombolo yokuqala. Isibonelo, 14x11 = 14x10 + 14 = 154.
- Enye indlela yokubala ngokushesha izinombolo ezinkulu engqondweni isebenza ngokuphindaphindiwe ngu-5. Lesi simiso sifanele kunoma iyiphi inombolo edingeka ukuba ihlukaniswe ngu-2 ekuqaleni. Uma umphumela uyi-integer, kufanele ubeke i-zero ekugcineni. Isibonelo, ukuthola ukuthi 504 uzokwandiswa kangakanani ngu-5. Ukuze wenze lokhu, 504/2 = 252 futhi kuthiwe ekupheleni kwe-0. Ngenxa yalokho, sithola i-504x5 = 2520. Uma, uma uhlukanisa inombolo, awutholi inamba, udinga nje ukususa i-comma. Isibonelo, ukuthola ukuthi izikhathi ezingu-173 zanda kangakanani ngo-5, udinga 173/2 = 86.5, futhi emva kwalokho ususa nje i-comma, futhi kuvela ukuthi i-173x5 = 865.
- Sifunda ukuthi singashesha kanjani ukubala engqondweni izinombolo ezimbili, ngokufaka. Okokuqala udinga ukwengeza amashumi, bese kuthi, amayunithi. Ukuze uthole umphumela wokugcina, kufanele wengeze imiphumela emibili yokuqala. Isibonelo, sizokwazi ukuthi kungakanani okungu-13 + 78. Isenzo sokuqala: 10 + 70 = 80, nesesibili: 3 + 8 = 11. Umphumela wokugcina uzoba kanje: 80 + 11 = 91. Le ndlela ingasetshenziswa uma umuntu kufanele asuse omunye kusuka kwinombolo eyodwa.
Esinye isihloko esiphuthumayo ukuthi singakanani ngokushesha ukubala amaphesenti engqondweni. Futhi, ukuze uthole ukuqonda okungcono, cabanga ngesibonelo sokuthola kanjani inombolo engu-15%. Okokuqala, thola u-10%, okungukuthi, uhlukanise ngo-10 bese ufaka isigamu somphumela -5%. Thola u-15% wezingu-460:
Kukhona enye indlela, ukuthila kanjani intshisekelo. Isibonelo, uma udinga ukunquma ukuthi kungakanani okungu-6% wezingu-400. Okokuqala, kuyadingeka ukuthola u-6% wezingu-100 kanti lokhu kuzoba ngu-6 Ukuthola u-6% wezingu-400, udinga u-6x4 = 24.
Uma udinga ukuthola u-6% wezingu-50, kufanele usebenzise le algorithm: 6% kwekhulu ngu-6, kanti ngo-50, lena yingxenye, okungu-6/2 = 3. Ngenxa yalokho, kuvela ukuthi u-6% we-50 ngu-3.
Uma inombolo ofuna ukuthola iphesenti engaphansi kwezingu-100, kufanele uhambise i-comma ngakwesobunxele. Isibonelo, ukuthola u-6% wezingu-35. Okokuqala, thola u-6% wezingu-350 futhi kuzoba ngu-21. Inani le-6% elifanayo ngo-35, ngu-2.1.
