Astaamaha isugeynta iyo isku dhufashada ee abyoone

	Isugeyn	Isku dhufasho
oodnaan:	a + b waa abyoone	a × b waa abyoone
Hormogalnimo:	a + (b + c) = (a + b) + c	a × (b × c) = (a × b) × c
Xeerka kala-hormarinta:	a + b = b + a	a × b = b × a
Jiritaanka ah Asalmadoorshe:	a + 0 = a	a × 1 = a
Jiritaanka ah Weydaarka kutirsane:	a + (−a) = 0	Weydaarka kutirsane sida caadiga ah maba jiro.
Kala dhigid:	a × (b + c) = (a × b) + (a × c) iyo (a + b) × c = (a × c) + (b × c)
No Qaybiye eber: (*)		Haddii a × b = 0, kadib a = 0 ama b = 0 (ama labodooda oo isla jira)
