Ukuhlukaniswa kwenombolo ibe ngamatemu amancane

Kulolu shicilelo, sizocubungula ukuthi yimaphi amatemu amancane, nokuthi singayimela kanjani inombolo njengesamba sayo (noma ukubola kube yiyo). Sizophinde sihlaziye izibonelo ukuze sikuqonde kangcono indaba ethulwayo.

Isamba samagama amancane

Noma iyiphi inombolo yemvelo enamadijithi amaningi (iqukethe amadijithi amaningana) ingabhalwa njengesamba samagama amancane.

Ngokwesibonelo:

Inombolo “47” iqukethe amashumi amane namayunithi ayisikhombisa.

Okungukuthi 47 = 4 10 + 7 1 = 40 + 7

Isenzo esingenhla sibizwa ngokuthi ukubola kube ngamatemu amancane (noma isamba sawo), okuyizinombolo "40" kanye "7" kuleli cala.

izibonelo:

• 213 = 2 amakhulu + 1 amashumi + 3 amayunithi = 2 · 100 + 1 · 10 + 3 · 1 = + 200 10 3
• 409 = 4 amakhulu + 0 amashumi + 9 oyedwa = 4 · 100 + 0 · 10 + 9 · 1 = 400 + 9
• 5 = 380 izinkulungwane + 5 amakhulu + 3 amashumi + 8 amayunithi = 5 · 1000 + 3 · 100 + 8 · 10 + 0 · 1 = + 5000 300 80

Iziphindaphinda 1, 10, 100, 1000, njll. - lokhu kunjalo amayunithi amancane.

Isibonelo senkinga

Asibole inombolo 4 215 096 ngokwemibandela encane futhi unqume inani lamayunithi ebhithi ngayinye.

Isinqumo:

Inombolo enikeziwe iqukethe:

• 4 million;
• izinkulungwane ezingamakhulu amabili;
• izinkulungwane eziyishumi;
• izinkulungwane ezi-5;
• 0 amakhulu;
• 9 amashumi;
• 6 amayunithi.

Masibhale inombolo njengesamba samagama amancane:

4 215 096 = 4 · 1 000 000 + 2 100 000 + 1 10 000 + 5 1000 + 0 100 + 9 10 + 6 1 = 4 000 000 + 200 000 + 10 000 + 5000 + 90 + 6.

Ukuze sinqume ukuthi mangaki amabhithi amayunithi aqukethwe enombolweni, sivele siyibhale kabusha ibe yibhithi, inani lamayunithi okudingeka siwathole. Esimweni sethu, kuvela:
