Inqubo kwizibalo

Kulolu shicilelo, sizocubungula imithetho yezibalo mayelana nendlela okwenziwa ngayo izibalo (okuhlanganisa nezinkulumo ezinamabakaki, ukuphakamisa amandla noma ukukhipha impande), ezihambisana nezibonelo zokuqonda kangcono indaba.

Inqubo yokwenza izenzo

Siphawula ngokushesha ukuthi izenzo zicatshangelwa kusukela ekuqaleni kwesibonelo kuze kube sekupheleni, okungukuthi ukusuka kwesobunxele kuya kwesokudla.

Ukubusa okuvamile

okokuqala, ukuphindaphinda nokuhlukanisa kuyenziwa, bese kwengezwa futhi kukhishwe amanani aphakathi nendawo.

Ake sibheke isibonelo ngokuningiliziwe: 2 ⋅ 4 + 12: 3.

Ngaphezulu kwesenzo ngasinye, sibhale inombolo ehambisana nokuhlelwa kokwenziwa kwayo, okungukuthi isixazululo sesibonelo sinezinyathelo ezintathu eziphakathi:

• 2 ⋅ 4 = 8
• 12:3 = 4
• 8 + 4 = 12

Ngemva kokuzijwayeza okuncane, esikhathini esizayo, ungenza zonke izenzo ngeketango (emgqeni owodwa / eminingana), uqhubeka nenkulumo yokuqala. Esimweni sethu, kuvela:

2 ⋅ 4 + 12 : 3 = 8 + 4 = 12.

Uma kukhona ukuphindaphinda nokuhlukaniswa okuningana ngokulandelana, kwenziwa futhi ngokulandelana, futhi kungahlanganiswa uma kudingekile.

Isinqumo:

• 5 ⋅ 6 : 3 = 10 (ukuhlanganisa izinyathelo 1 no-2)
• 18:9 = 2
• 7 + 10 = 17
• 17 - 2 = 15

Iketanga lesibonelo:

7 + 5 ⋅ 6 : 3 – 18: 9 = 7 + 10 – 2 = 15.

Izibonelo ezinobakaki

Izenzo ezikubakaki (uma zikhona) zenziwa kuqala. Futhi ngaphakathi kwabo, ukuhleleka okufanayo okwamukelwe, okuchazwe ngenhla, kusebenza.

Isixazululo singahlukaniswa sibe yizinyathelo ezingezansi:

• 7 ⋅ 4 = 28
• 28 - 16 = 12
• 15:3 = 5
• 9:3 = 3
• 5 + 12 = 17
• 17 - 3 = 14

Lapho uhlela izenzo, isisho esikubakaki singabonakala ngokwemibandela njengenombolo ephelele / inombolo. Ukuze kube lula, sikugqamisile ochungechungeni olungezansi ngokuluhlaza:

15 : 3 + (7 ⋅ 4 – 16) - I-9: 3 = 5+ I-28 - 16 - 3 = 5+ 12 - 3 = 14.

Abakaki ngaphakathi kubakaki

Ngezinye izikhathi kungase kube namanye amabakaki (abizwa ngokuthi anesidleke) phakathi kwabakaki. Ezimweni ezinjalo, izenzo kubakaki bangaphakathi zenziwa kuqala.

Isakhiwo sesibonelo kuketango sibukeka kanje:

11 ⋅ 4 + (10:5 + (16:2 - 12:4)) = 44 + (2+ I-8 - 3) = 44 + (2+ 5) = 51.

Exponentiation / ukukhishwa kwezimpande

Lezi zenzo zenziwa kwasekuqaleni, okungukuthi nangaphambi kokuphindaphinda nokuhlukanisa. Ngaphezu kwalokho, uma zithinta izinkulumo ezikubakaki, izibalo ezingaphakathi kuzo zenziwa kuqala. Cabangela isibonelo:

Inqubo:

• 19 - 12 = 7
• 7² = 49
• 6² = 36
• 4 ⋅ 5 = 20
• 36 + 49 = 85
• 85 + 20 = 105

Iketanga lesibonelo:

6² + I-19 - 12² + 4 ⋅ 5 = 36 + 49 + 20 = 105.
