Zero ngokwayo oyintsobi umdla kakhulu. Lulodwa yanto, ukungabikho imilinganiselo, yaye ecaleni kwenye nani ukwandisa ukubaluleka kwayo ngamaxesha-10. Naliphi inani ukuya amandla zero sinike 1. Lo mqondiso isasetyenziswa nangoku yamaMaya impucuko, kwaye ngabo yalwa ukuba ingcamango 'ekuqaleni unobangela. " Nkqu ikhalenda wabantu Maya lwaqalisa mini-zero. Kwaye lo mzobo esidityaniswe umlomo engqongqo.
Ukususela kwiminyaka yesikolo yokuqala, siye safunda ngokucacileyo kulawula "akakwazi ukwahlula ngu zero." Kodwa ukuba umntwana uyabonakala abaninzi elukholweni kunye abadala amagama bangenakufane Akuthandabuzeki ukuba ethubeni maxa wambi usafuna ukuqonda oonobangela, ukuqonda isizathu sokuba imithetho ethile ziye zasekwa.
Kutheni Ungayohlula ngu zero? Kulo mbuzo ndifuna ukufumana ingcaciso ecacileyo enengqondo. Xa utitshala kwibanga lokuqala wawungenako ukusikhulula, ngenxa kwimathematika imithetho zicacisiwe ngoncedo kwizibalo, yaye ngelo ubudala, yaye bengazi ukuba yintoni na. Kwaye ngoku lifikile ixesha lokuba ukuqonda kwaye ufumane inkcazelo ecacileyo enengqondo ukuba kutheni ungakwazi kuzabela zero.
Inyaniso yokuba ngezibalo, ababini kuphela imisebenzi ezine ezisisiseko (+, -, x, /) kunye ezizimeleyo ziziwe: phinda ngaphandle. Ezinye yokusebenza kucingwa ukuba kufunyanwa. Cinga umzekelo olula.
Ndixelele, wobeka phi na ufumana xa uthabathe 18 20? Ngokuqhelekileyo, ngo kwentloko yethu ngoko nangoko ukuphendula khona; kuya kuba 2. Kwaye njengoko siza yoko onjalo? Ukuze ezinye lo mbuzo usenokubonakala engaqhelekanga - emva konke, yonke into icacile, kwenzeka ntoni 2, umntu uya kuchaza ukuba phakathi eesenti-20 no-18 bethatyathwe wavuka ngeepeni ezimbini. Ngokusengqiqweni zonke iimpendulo ezi azikho uyathandabuza, ke, ukusombulula le ngxaki kufuneka ezahlukeneyo ukusuka kwindawo imbono lwemathematika. Kwakhona, ukuba imisebenzi ephambili izibalo kukho uphinda-phindo kunye Ukongeza, kwaye ngokunjalo kule meko Impendulo siyifumana ekusombululeni inxaki ilandelayo: x + 18 = 20 Ukusuka apho kulandela ukuba x = 20 - 18, x = 2. Kubonakala, ngoko kutheni zonke iinkcukacha ukupeyinta? Ngapha koko, njengokuba bonke elula aphantsi. Nangona kunjalo, ngaphandle kunzima ukuchaza ukuba kutheni ungakwazi kuzabela zero.
Ngoku makhe sibone ukuba kwenzeka ntoni xa unqwenela 18 kuwabela zero. Kwakhona aseke inxaki 18: x = 0. Ekubeni ukusebenza candelo livela ukuphindaphindwa iinkqubo iinguqu equation lwethu sinokuyifumana x * 0 = 18. Lo Ndaqalisa kunye ngunomji apho. Naliphi na inani kweminye endaweni xa iphinda phindiweyo ngo zero unika 0 kwaye ufumane-18, zange siphumelele. Ngoku kucace kakhulu kutheni ungakwazi kuzabela zero. Zero ngokwayo lungahlulwa-hlulwa zibe naliphi na inani oyithandayo, kodwa ngokuchasene - Awu, akukho ndlela.
Kwaye kwenzeka ntoni ukuba zero umahlule yedwa? Oku kubhalwe kule fom: 0 0 = x, okanye x * 0 = 0. Eli equation unenani engenasiphelo izixazululo. Ngoko ke, imiphumo iba obungapheliyo. Ngoko ke, lo msebenzi sisahlula ngu zero , yaye kulo mzekelo, nayo, akukho ntsingiselo.
Division ngu 0 kungunozala iziqhulo ezininzi wengqikelelo zemathematika, awothi ezinqwenelekayo na baxakwe nawuphi na umntu makangazi. Ngokomzekelo, cinga inxaki: x * 4 - 20 * x = 7 - 35. nikeza kwizibiyeli 4 kwicala lasekhohlo kunye nelungelo 7. afumane i-4 * (x - 5) = 7 * (x - 5). Ngoku phinda icala lenxaki asekhohlo nasekunene yi iqhezu 1 / (x - 5). Inxaki kuthatha uhlobo: 4 * (x - 5) / (x - 5) = 7 * (x - 5) / (x - 5). Iza kunciphisa iqhezu ngu (x - 5), kwaye siya kuphuma ukuba 4 = 7. Ukusuka oku siyakwazi ukubona ukuba lo-2 * 2 = 7! Kakade ke, iqhinga apha kukuba esi ingcambu lenxaki ilingana no-5 kwaye kwakungenakwenzeka ukunciphisa iqhezu, ekubeni kwakhokelela hlula ngu zero. Ngoko ke, lo gama amaqhezu kuncitshiswa kufuneka soloko ujonge ukuba iqanda akukho kwenzeka ukuba elingezantsi, kungenjalo kuya kuba yinto engalindelekanga.
