Guryaha is-dhexgalka

Hanti isku-dhafan Ku darso Kala goyn
gudbin Hanti x + y = y+ x x – y ≠ y – x
Xiriiriye Hanti x + (y + z) = (x + y) +z (x - y) - z ≠ x - (y - z)
Aqoonsiga Hanti x + 0 = x = 0 + x x – 0 = x ≠ 0 – x
Xiritaanka Hanti x + y ∈ Z x - y ∈ Z

Sidoo kale ogow, maxay yihiin sifooyinka kala-goynta?

Astaamaha Kala-goynta Tani waxay ka dhigan tahay in dhammaan tirooyinka aan hoos lagu xirin kala goyn. Haddii a iyo b ay yihiin laba tiro oo dhan iyo a - b = c, markaa c had iyo jeer ma aha tiro dhan. Qaado a = 7 iyo b = 5, a - b = 7 - 5 = 2 iyo b - a = 5 - 7 = -2 (maaha tiro dhan).

Intaa ka dib, su'aashu waxay tahay, waa maxay sifooyinka shaandhada? Hanti Wadareed Ku darso, Hantida associative Marka lagu daro, Hanti Qaybinta, Hantida Aqoonsiga Wax-ku-darka, Hantida Aqoonsiga ee Isku-dhufashada, Hantida rogan ee Wax-ku-darka iyo Hantida eber ee isku-dhufashada. Saddexda astaamood ee tirooyinka ayaa la sharaxay.

Si sahal ah, waa maxay 4-ta astaamood ee kala-goynta?

Waxaa jira afar (4) aasaasiga ah guryaha ee tirooyinka dhabta ah: kuwaas oo ah; wada-xiriir, wadaag, qaybin iyo aqoonsi. Kuwaas guryaha kaliya codso hawlaha isku-darka iyo isku-dhufashada. Taas macnaheedu waa kala goyn kala qaybsanaantuna ma laha kuwaas guryaha lagu dhisay.

Immisa guri ayaa jira?
