Kulolu shicilelo, sizocubungula ukuthi ingubani kanye nezisho ezifanayo, siklelise izinhlobo, futhi sinikeze nezibonelo zokuqonda kangcono.
Okuqukethwe
Izincazelo zobuwena kanye nokuvezwa kobuwena
Identity iwukulingana kwe-arithmetic izingxenye zayo ezilingana ngokufanayo.
Izinkulumo ezimbili zezibalo ngokulinganayo (ngamanye amazwi, ziyefana) uma zinenani elifanayo.
Izinhlobo zobunikazi:
- Inombolo Zombili izinhlangothi zesibalo zihlanganisa izinombolo kuphela. Ngokwesibonelo:
- 6 + 11 = 9 + 8
- 25 ⋅ (2 + 4) = 150
- Ongokoqobo – umazisi, obuye ube nezinhlamvu (okuguquguqukayo); kuyiqiniso kunoma yimaphi amanani abawathathayo. Ngokwesibonelo:
- 12x + 17 =
15x – 3x + 16 + 1 - 5 ⋅ (6x + 8) =
30x +40
- 12x + 17 =
Isibonelo senkinga
Nquma ukuthi yikuphi ukulingana okulandelayo okuwubunikazi:
- 212 + x =
2x – x + 199 + 13 - 16 ⋅ (x + 4) =
16x +60 - 10 – (-x) + 22 =
10x +22 - 1 – (x – 7) =
-x-6 - x2 + 2x = 2x3
- I-15 - 32 =
152 + 2 ⋅ 15 ⋅ 3 – 32
Impendulo:
Ubunikazi buwukulingana kokuqala nokwesine, ngoba kunoma imaphi amanani x zombili izingxenye zazo zizohlala zithatha amanani afanayo.
