(ii) Amakulu g’Omulamwa gwa Kibalirampuyibbiri

Yintegya ziba namba za kibalirampuyibbiri, ekitegeeza nti ziriko oluuyi olwa kiddannyuma (negatiivu ) n’oluuyi olwa kiddamaaso(pozitiivu). Namba eza kibalirampuyibbiri n’olwekyo zibaako oluuyi olwa kiddamaaso (pozitiivu) n’oluuyi olwa kiddannyuma (negatiivu).

Mu namba za kirumirampuyibbiri (yintegya), amateeka g’okugabanyaamu ge gamu ne ag’okukubisaamu ate ag’okugatta ge gafuga okwawuza.

Singa tutwaala ebintu ebirungi okuba n’akalaga k’ekibalo aka kiddamaaso + ate ebibi ne biba n’akalaga aka kiddannyuma, engeri y’okujjukiramu ebigoberero by’ekibalo eri mu bino wammanga:

”Ebintu ebirungi (+) bwe bituuka ku bantu abalungi   (+) ekivaamu kiba kirungi (+). (Ebirungi + abalungi + = + Mu kugatta oba okukubisaamu kibalirampuyibbiri  n’olekyo kiddamaaso bw’ogattako oba n’okubisaamu kiddamaaso  ofuna ansa eri mu kiddamaaso.

Kyokka ebintu ebibi (-) bwe bituuka ku bantu abalungi (+) ekivaamu kiba kibi (-).

Ebibi - abalungi + = -  Mu kugatta n’okukubisaamu kiddannyuma  bw’ogigatta oba n’okubisaamu ne kiddamaaso , ansa eba mu kiddannyuma

Ate era ebintu ebirungi (+) bwe bituuka ku bantu ababi (-) kiba kibi , (-). (ebirungi + ababi - = -

So ng’ate ebintu ebibi (-) bwe bituuka ku bantu ababi (-) ekyo kiba kirungi (+). ebibi - ababi - = +

(iii) Okukubisaaamu n’Okugabiza mu kibalirampuyibbiri

Nnyonnyoka ebigoberero bino:

Ansa eri mu pozitiivu kubanga akafunza/ ka kigabanya (even); kitegeeza waliwo namba y’obubonero bwa negatiivu eya kigabanya (even) mu kibuuzo.

(b) (-2)7 = (-2)(-2)(-2)(-2)(-2)(-2)(-2) = - 128

Wano ekivuddemu kiri mu negatiivu kubanga kipowesa si ya kagabanya n’olwekyo omuwendo gw’obubonero obwa negatiivu mu kibuuzo si gwa kagabanya.

Manya: Singa ekibuuzo kiwandiikibwa n’akabonero aka negatiivu kyokka nga tekuli bukomera (no parentheses), ansa erina kubeera mu negatiivu.

Okugeza:

-33 = -(3)(3)(3) = - 27

-44 = -(4)(4)(4)(4) = - 256

Wano oba okiraba nti waliwo akabonero ka negatiivu kamu kokka n’olwekyo.

(vi) Akafunza bwe kaba mu Negatiivu

Akafunza bwe kaba mu negatiivu kitegeeza nti namba eri wakati wa 0 ne 1. (nkutulemu/fraction). N’olwekyo namba erina akafunza akali mu negatiivu yenkana n’ensulike (reciprocal) yayo nga erina akafunza aka pozitiivu. Okugeza:

3-4= 1/(34)=1/81 Kikwetaagisa okunnyonnyoka emifunza okusobola okusobola okukola okubalanguza okw’enjawulo naddala mu namayingo (polynomials), omuli nnyingemu (monomials), nnyingobbiri (binomials), ne nnyingossatu (trinomials). Ebyokulabirako: (a) Sonjola (-3)3 Eky’okukola: Laga nti kino kitegeeza kye kimu ne (-3)(-3)(-3) = -27

Lwaki? Laba nti waliwo obukomera. Ekitegeeza nti ekikunizo kiri (-3) eya kyesatuza (cubed). Akafunza “3” kalaga nti entobo (-3) erina okwekubisibwamu yo yennyini emirundi esatu..

(b) Sonjola -43 - (-4)2 + (-3)2

Ekibazo :

    -(4)(4)(4) - (-4)(-4) + (-3)(-3) = 
    -64 - 16 + 9 =
    - 39

Okusonjola omweyoreko ogulimu obufunza ky’okola kwe kusooka okulaba oba nga:  Mulimu namba eya negatiivu. Ky’olina okujjukira:  Omweyoreko gulimu obukomera. Tandikanga na kusonjola ekintu kyonna ekiri munda mu bukomera. Eky’okulabirako:

       -54   = -(5)(5)(5)(5)            = -625
       (-5)4 = (-5)(-5)(-5)(-5)         = 625

Okusonjola emyeyoreko egirimu obufunza kyangu nnyo. Ky’okola kwe kusooka okulaba oba mulimu namba eza negatiivu n’obulaga obwa negatiivu kubanga buno bukyusa ekibazo. Eky’okulabirako: 3. Sonjola: yx4z2

                y = 2, x =3, z = 5
