Division e kore: he aha e kore?

whakaritea kanga tino i runga i te wehenga i te kore e ara i roto i te kura nui teina. Tamariki e kore te nuinga e whakaaro e pā ana ki ona take, engari i roto i te hono mo'oní ki mohio he aha rāhuitia te tahi mea te, a he reira ngā, me te whai hua.

ngā mahi tauhanga

ngā mahi tātai, e kua whakaako i te kura, taurite i roto i ngā o te pāngarau. mōhio ana ratou e rua ki tonu i anake o enei ngā mahi - tua me te whakarea. E whakaurua ratou i roto i te ariā o te whaiaro, me hāngai atu mahi katoa ki te tau kotahi ara ranei tetahi e ki runga ki enei e rua. E ko, ko e taea e kore anake ki te wehe i te kore, ko te wehenga te tikanga.

Tangohanga me te wehenga

He aha ngā ngaro te toenga o te mahi? Ano, Kei te pai mohiotia te kura e, mo te tauira, tango wha i whitu - ka tango whitu tiakareti, e wha o ratou kai me te tatau i te hunga e toe. Ko te pāngarau e kore e whakaoti te raruraru o kai sweets me te tikanga kite ratou rawa rerekē. Hoki ratou i reira he tua anake, te mea he lekooti o 7 - 4 = te tokomaha i te mea te moni o te tau 4 e kia rite ki te 7. Ko, hoki mathematicians, 7 - 4 - te whārite poto x + 4 = 7. E kore te mea he tangohanga, engari te raruraru tenei - ki te kitea he maha e hiahia ana koe ki te hoatu i roto i te wahi o te x.

Ko te taua pā ki te wehenga me te whakareatanga. Wehewehe tekau ki te rua, ka waha mladsheklassnikov i tekau candies ki e rua puranga rite. Mathematician taua konei e kite whārite: 2 · x = 10.

A riro te reira mārama he aha te mea wehenga hē e kore: ko reira taea noa. Record 6: 0 kia tahuri ki te whārite 0 · x = 6. I roto i te mau parau te tahi atu, e hiahia ana koe ki te kitea i te maha e taea kia maha e te kore me te whiwhi 6. Otira e matau ana tatou e te whakareatanga e kore e homai tonu te kore. Ko te taonga faufaa o te kore tenei.

Ko te kupu, i reira te mea he maha taua e, whakanuia i te kore, e hoatu etahi tau atu atu i te kore. Na, tenei whārite kua kahore otinga, kahore he tatau taua, e pai kia fakafekau'aki ki te lekooti o 6: 0, e ko, e kore e hanga i taua tikanga. I runga i tona senselessness me mea e rāhuitia wehenga i te kore.

Kei te kore wehea e te kore?

Te reira taea ki te kore wehea e te kore? Ko te whārite 0 · x = 0 kore he uaua, a taea te tangohia rite te x te nuinga kore ka whiwhi 0 · 0 = 0. Na 0: 0 = 0? Otiia ki te, hei tauira, te tango hoki wae x, riro ano 0 · 1 = 0. Ka taea te tangohia te reira i hoki x roto i whānui i tetahi tau e hiahiatia ana me te wehenga i te kore, me te hua ka noho te taua: 0: 0 = 9, 0: 0 = 51, me te pera i runga i.

Ko te kupu, i roto i tenei whārite, ka taea e koe te kōkuhu i tetahi maha o rawa, a kore koutou e taea e te tīpako i tetahi ngā, e kore e taea ki te whakatau i te tini o tohua record 0: 0. Ko, tenei record hoki e kore e hanga tikanga, me wehenga i te kore tonu e taea: ia kihai wehea noa ki a ia.

Ko te āhuatanga nui o te mahi wehenga, e ko, te whakarea, me te maha e pā ana ko te kore.

tonu te pātai: e kore e taea e te aha wehe i te kore, engari e taea te tango ai? Ka taea e tatou te mea e haamata tenei pāngarau ki tenei raruraru ngā. Hei kitea te whakahoki, me ako koe i te whakamāramatanga pāngarau ōkawa o huinga tau, me te whakatau i nga ngā mahi ki runga ki a ratou. Hei tauira, i reira e kore e ohie anake, engari ano hoki tau matatini, wehenga e rerekē i te wehenga tikanga. E kore te mea i roto i te marautanga kura, engari te kauwhau whare wānanga i roto i te pāngarau tīmata ki tenei.
