Emiramwa gy’Ekibalangulo emigandawaze

1. Ekibalangulo(Mathematics)

Lino “sessomo” eriwagala obwongo nga lisengeka ebirowoozo nga lyogeza namba. Essomo lino n’olwekyo liyamba okukulaakulanya “ EkkyO”(kisomwa “Ekkyu”) y’omuntu. Ekibalangulo mu bumpi kiwandiikibwa “ekibalo”(maths). Gino gye gimu ku mibalanguzo( operational concepts) egyetaagisa mu sessomo lino:

3. Omugereeso gwa Namba 

        (Number theory)

Mu mugereeso gwa namba mulimu ebika bya namba eby’enjawulo omuntu anabeera omubalanguzi bye yetaaga okunnyonnyoka . Bye bino:

a) Namba eza kibazo (cardinal numbers)

b) Namba ezibala (counting numbers)

3. Emisingi gya namba oba emisimba 

        (Number bases)

Omusingi gwa namba(omusimba) eba “nsengekera ya namba”(number system) esimbira mu digito ez’enjawulo.

• Emisingi gya namba (number bases)

• Omusingi gwa namba ogwa bbiri (number base two)

• Omusingi gwa namba ogwa Satu (base three)

• Omusingi gwa namba ogwa nnya (base four)

• Omusingi gwa namba ogwa ttaano (base five)

• Omusingi gwa ogwa mukaaga (base six)

• Omusingi gwa namba ogwa musanvu (base seven)

• Omusingi gwa namba ogwa munaana (base eight)

• Omusingi gwa namba ogwa mwenda (base nine)

• Omusingi gwa namba ogwa kkumi (base ten)

N’okweyongerayo. Omusingi gwa namba ogwa bbiri gusimbira mu digito bbiri (0 ne 1) , omusingi gwa namba ogwa satu gusimbra mu digito satu (0,1, ne 2), omusingi gwa namba ogwa nnya gusimbira mu digito nnya(0,1,2 ne 3) ate omusingi gwa namba ogwa kumi gusimbira mu digito kumi(o.1.2.3.4.5.6.7.8. ne 9),

Mui bufunze “omusungi gwa namba” ka nguyite “omusiimba”,Buli musinga gwa namba kw’egyo gyendaze waggulu era guyinza okuwandiikibwa mu bufunze nga wano wansi:

Emisingi gya Namba(Number Systems or number bases) Mu bufunze English short form

2 Omusungi gwa namba ogwa bbiri Omunabbiri (binary)

3 Omusingi gwa namba ogwa satu Omunassatu (ternary)

4 Omusingi gwa namba ogwa nnya Omunannya (quaternary)

5 Omusingi gwa namba igwa ttaano Omunattaano (Quinary)

6 Omusingi gwa namba ogwa mukaaga Omunekaaga (Senary)

7 Omusungi gwa naba ogwa musanvu Omusenvu ( Septenary)

8 Omusingi gwa namba ogwa munaana Omunenna (octal)

9 Omusingi gwa namba ogwa mwendas Omunenda (nonary)

10 Omusingi gwa namba ogwa kkumi Omunekkumu decimal)

Emisingi gya namba okuva ku gw’ekkumi n’ogumu okweyongera waggulu oyinza okugisoma nga si mifunze bwoti:

Omusingi gwa namba ogwa kumi n’emu (undenary)

Omusingi gwa namba ogwa kumi na bbiri (duodecimal)

Omusingi gwa namba igwa kumi na satu (hexadecimal)

Omusingi gwa namba ogwa kumi na nnya (vigesimal)

Omusingi gwa namba ogwa kumi na ttaano (sexagesimal)

Omusingi gwa namba ogwa kumi na mukaaga

Nga omubalanguzi atandika , manya bino:

• Mu nsengekera y’omuwendo gw’ekifo, buli musimbalaala (column) gubaamu digito ezikiikirira obufunza bwa namba ey’ekikolo obw’omudding’anwa.

• Mu nsengekera y’omunekkuni, ekikolo(ensingi) kiba 10.

• Namba meka ezikozesebwa mu Nsengekera ya Namba? Ensengekera ya namba ey’omunekkumi (omusingi gwa namba ogwa kkumi) gwe tukozesa buli lunaku guzimbirwa “obutaffaali” buno kkumi {0,1,2,3,4,5,6,7,8,9} ekintu ekiguyisa omusingi ogwa -10.

• Digito ez’omunebbiri zisobola kuba 0 oba 1, ekiziyisa omunebbiri (omusingi ogwa-2). Yadde nga tusobola okuba n’emisingi gya namba (emisiimba) egy’enjawulo mingi , wano essira tugenda kulissa ku misiimba esatu egisinga okukozesebwa mu bulamu ne mu sayansi. Emisingi gya nmab gino esatu gye :

(i) Omunakkumi(=Omusingi gwa namba ogwa kkumi)

(ii) Omunabbiri (Omusingi gwa namba ogwa bbiri)

(iii) Omusimba ogwa kumi na mukaaga.

Mu lufuutifuuti , omunnakkumi gwe guyitibwa “base 10” ate omunabbiri ne guba “binary base”. Omusingi gwa namba ogwa 16 gwe guyitibwa “hexadecimal”

4. Okulambulula Namba 

   (Factoring numbers)

Okusobola okunnyonnyoka essomo ly’ekibalangulo eky’okulambulula namba obulungi, wetaagisa okumanya egimu ku miramwa egikozesebwa naddala emiramwa nga :

    (Fractions)

Emiramwa egyetaagisa okusobola okubaza oba okusonjola emikutule gye gino:

(i)Ebitundu by’Omukutule(Parts of a Fraction) 

(a) Kinnawansi ne  Kinnawaggulu. Mu mukutule guno  namba eri waggulu eyitibwa kinnawaggulu ate eri wansi kinnawansi:  11	
                      13

(b) Nambuluzo Eyawamu Esingayo (Greatest Common Factor)

(c) Enkubise Eyawamu (Common Multiple)

(d) Enkubise Eyawamu Esembayo(Lowest Common Mutlple)

Okugatta emikutule egirina kinnawansi y’emu kuba kulya mungu buteesokoola naye bwe giba ne kinnawansi ez’enjawulo oba olina okusooka okuzuula “kinnawansi ey’awamu”(common denominator). Okuzuula kinnawansi ey’awamu weyambisa enkubise ey’awamu era eno gy’osooka okunonnya.

Omugereko guyinza obutabaamu bamemba, ntegeeza obutabaamu kintu kyonna era Omugereko nga guno guyitibwa Omugereko omwangaala (empty set). Kino kiragibwa n’akabonero , ekisomwa (fi). Ebintu oba bamemba ababeera mu mugereko A balagibwa nga n (A), ekitegeeza nti n ( ) = 0, ekitegeeza nti Omugereko A teguliimu erementi yonna. Omugereko gulimu emiramwa gino :
