Division ngu zero: kutheni?

ban okungqongqo ku hlula ngu zero siwiswa nokuba kwisikolo samabanga aphakamileyo. Abantwana badla musani ukucinga malunga oonobangela, kodwa eneneni ukwazi isizathu sokuba into ethile akuvumelekanga, kwaye 'umdla yaye iluncedo.

imisebenzi arithmetic

imisebenzi arithmetic, ezo ezifundiswa esikolweni, ukungalingani ngokwemiqathango lwemathematika. Babona ngokupheleleyo kuphela ezimbini kwezi imisebenzi - ukudibanisa-phindo. Bona ifakiwe ingqikelelo ukuzeyisa, kunye nazo zonke ezinye iintshukumo kunye amanani ngendlela enye okanye enye zisekelwe phezu kwezi zimbini. Oko kukuthi, akunakwenzeka nje ukuba kuwabela zero, kodwa ukwahlukana ngokubanzi.

Ukukhupha uqhekeko

Yintoni engekhoyo Ezinye isenzo? Kwakhona, isikolo eyaziwa kakuhle ukuba, umzekelo, uthabathe ezine ukusuka abasixhenxe - uthabathe itshokolethi ezi ezisixhenxe, abane kubo badle, ubale nabo eziseleyo. Kodwa izibalo na ukusombulula ingxaki ukutya iilekese yaye ndiyaqonda ngokubanzi ezahlukileyo ngokupheleleyo. Kubo kukho kuphela Ukongeza, ukuba unalo irekhodi 7 - 4 = inani yona udibaniso lwenani 4 iya kulingana 7. Oko kukuthi, ukuba zezibalo, 7 - 4 - i equation yokuqhagamshela izixhobo x + 4 = 7. Eli asilo ukuthabatha, kodwa ingxaki - ukufumana inani ukuba kufuneka ubeke endaweni ye x.

Kukwasebenza kwanjalo kuyo kwicandelo phinda. Balani ezilishumi ukuya ezimbini, mladsheklassnikov ikuxelela epha ezilishumi zibe ziimfumba ezimbini ngokulinganayo. Sezibalo efanayo apha ubone equation: 2 · x = 10.

Kwaye ke kucaca kutheni division mthethweni ngu zero: ukuba nje akunakwenzeka. Rekhoda 6: 0 kufuneka zitshintshwe zibe inxaki 0 · x = 6. Ngamanye amazwi, ufuna ukufumana inani ukuze iphindaphindwe zero kwaye ufumane 6 Ke siyazi ukuba phindo ngu zero usoloko unika zero. Le propati ibalulekileyo zero.

Ngoko ke, kukho inani lokuba, phinda ngo zero, uya kunikela ezinye kwe zero inani. Ngoko ke, lo lenxaki akukho sicombululo, akukho nani enjalo, neliya kuthi ngamazinga ingxelo 6: 0, oko kukuthi, loo nto ayenzi mqondo. Ukungabi nangqondo yayo kwaye bathi ukuthintela hlula ngu zero.

Nothi umahlule ngo zero?

Ngaba kunokwenzeka ukuba zero umahlule ngo zero? Inxaki 0 · x = 0 Akukho nzima, kwaye kuthathwe njengoko x kakhulu zero kwaye ufumane 0 · 0 = 0. Ngoko 0: 0 = 0? Ke ukuba, umzekelo, zithabathele x unit, wafumana 0 · 1 = 0. It mabasiwe x ngokubanzi naliphi na inani oyifunayo kwaye silahlule ngu zero, yaye oko kuya kuhlala injalo: 0: 0 = 9, 0: 0 = 51 njalo on.

Ngenxa yoko, kweli lenxaki, ungakwazi ukufaka naliphi na inani ngokupheleleyo, kwaye awukwazi ungakhetha nawuphi na ethile, akunakwenzeka ukuba mingaphi okhethwe irekhodi 0: 0. Oko kukuthi, le ngxelo kwakhona akwenzi ngqiqo, yaye kwisahlulo ngu zero nangoku akunakwenzeka: yena babelana nokuba xa yena.

Loo nto inkalo ebalulekileyo nendlela yokwahlula, oko kukuthi, i-phinda inani enxulumene zero.

Umbuzo usahleli: kutheni walhule ngu zero, kodwa kuxhuzulwa? Sinokuthi le izibalo iqala nale ngxaki umdla. Ukuze ufumane impendulo, kufuneka ufunde kwenkcazelo ngokusesikweni zemathematika iiseti lwamanani kwaye ukuhlangabezana imisebenzi kubo. Ngokomzekelo, akukho zilula kuphela, kodwa amanani ezintsonkothileyo, ukwahlulwa eyahluke ukusuka ukwahlulwa oluqhelekileyo. It ayifakwanga phakathi kwikharityhulam yesikolo, kodwa iintetho eyunivesithi kwimathematika eqala ngalo.
