Okuqukethwe
Kulolu shicilelo, sizocubungula ukuthi ayini amadijithi ezinombolo, futhi sinikeze izibonelo zokuqonda kangcono indaba yethiyori.
Incazelo Yezinga
Njengoba sazi, yonke into iqukethe izinombolo, lapho kukhona eziyishumi kuphela: 0, 1, 2, 3, 4, 5, 6, 7, 8 no-9.
Ukukhishwa – lena indawo/indawo idijithi ekuyo enombolweni.
Indawo ibalwa ukusuka ekugcineni kwenombolo kuye ekuqaleni kwayo. Futhi kuye ngendawo ehlala kuyo, isibalo singaba nencazelo ehlukile.
Amadijithi ahlelwa ngendlela elandelayo (ngohlelo olukhuphukayo: ukusuka kwencane kuye kwemdala kunabo bonke, okungukuthi ukusuka kwesokudla kuye kwesobunxele):
- amayunithi;
- izingane;
- amakhulu;
- izinkulungwane, njll.
Izibonelo
Njengesibonelo, ake sibhekisise inombolo 5672 (funda njenge izinkulungwane ezinhlanu namakhulu ayisithupha namashumi ayisikhombisa nambili), noma kunalokho, siyihlukanisa ibe amadijithi.
- inombolo 2 endaweni yokugcina isho amayunithi amabili.
- Isi-7 singamashumi ayisikhombisa;
- 6 – amakhulu ayisithupha.
- 5 – izinkulungwane ezinhlanu.
Labo. inombolo 5672 ingahlukaniswa ibe amadijithi kanje:
amanothi:
- Kunezinombolo ezingenalo uhlobo oluthile lwedijithi, njengoba kufakazelwa inombolo enguziro endaweni yayo. Isibonelo, ukwakheka kwezinombolo zenombolo 10450 kubukeka kanje:
10 ⋅ 10000 + 0 ⋅ 1000 + 4 ⋅ 100 + 5 ⋅ 10 + 0 = 10450. - Amayunithi ayishumi anoma yisiphi isigaba alingana neyunithi eyodwa yesigaba esilandelayo, esiphezulu. Ngokwesibonelo:
- Abayi-10 = ishumi eli-1;
- 10 amashumi = 10 amakhulu;
- 10 amakhulu = 1 inkulungwane, njll.
- Uma kucatshangelwa leli phuzu elingenhla, kuvela ukuthi inani ledijithi kwidijithi ngayinye elandelayo (elidala) likhuphuka izikhathi ezingu-10, okungukuthi iyunithi eyodwa ingaphansi ngokuphindwe ka-10 kuneshumi elilodwa, ishumi liphindwe ka-10 ngaphansi kwekhulu, futhi kanjalo. ku.
