Me pēhea te tatau a te pauna maha-upoko i ngā huinga?

Kua hangaia e te hangarau ngā rāngai nui i ngā tau kua pahure ake nei, tae atu ki te umanga tākai. E whakamahia whānuitia ana ngā mīhini pauna maha-upoko i roto i ngā pakihi katoa, ā, ka puta ngā hua mā te tikanga rorohiko iti e whakahaeretia ana, e tika ana hoki. E kiia ana hoki ngā mīhini pauna maha-upoko he mīhini pauna whakakotahi nā te mea ko tā rātou mahi he tango i te huinga taumaha pai rawa atu mō tētahi hua.

He mīhini pauna maha-upoko e whakamahia ana i roto i te umanga tākai hei pauna me te tohatoha i ngā hua pēnei i te kai, ngā rongoā, me ngā matū. He maha ngā pane pauna (i waenga i te 10 me te 16 te nuinga), kei roto i ia pane he pūtau uta, e whakamahia ana hei ine i te taumaha o te hua.

Hei tatau i ngā huinga, ka whakamahia e te pauna maha-upoko tētahi hōtaka rorohiko kua whakaritea me te taumaha whāinga mō te hua ka tohatohahia me te taumaha o ia hua takitahi. Ka whakamahia e te hōtaka ēnei mōhiohio hei whakatau i te huinga tino pai o ngā hua hei whakatutuki i te taumaha whāinga.

Ka whakaarohia hoki e te kaupapa ngā āhuatanga maha pēnei i te mātotoru o te hua, ngā āhuatanga rere, me te tere e hiahiatia ana o te mīhini. Ka whakamahia ēnei mōhiohio hei whakapai ake i te tukanga pauna me te whakarite kia tika, kia whai hua hoki te tohatoha o te hua.

Ka whakamahia e te pauna maha-upoko tētahi tukanga e kīia nei ko te "pauna whakakotahi" hei whakatau i te huinga hua tino pai hei tohatoha. Kei roto i tēnei ko te pauna i tētahi tauira iti o te hua me te whakamahi i ngā rauropi tatauranga hei whakatau i te huinga hua tino whai hua hei whakatutuki i te taumaha e hiahiatia ana.

Kia whakatauhia te huinga tino pai, ka tohatohahia ngā hua e te pauna maha-upoko ki roto i tētahi putea, i tētahi ipu rānei, kia rite ai mō te tākai. He tino aunoa te tukanga katoa, ā, ka taea te whakaoti i roto i ngā hēkona ruarua, ka waiho hei whiringa rongonui mō ngā mahi tākai nui-rahi.

Ko te mahi matua ka puta ina taurite te tohatoha o te hua. Ko te mahi matua o te whāngai raina ko te tuku hua ki te pūwero whāngai, te wāhi e puta ai te mahi. Hei tauira, i roto i te mīhini pauna maha-upoko 20, me 20 ngā whāngai raina e tuku ana i ngā hua ki ngā pūwero whāngai e 20. Ka mutu, ka ringihia ēnei ihirangi ki roto i te pūwero pauna, he pūtau kawenga kei roto. Kei ia upoko pauna tōna ake pūtau pauna tika. Ka āwhina tēnei pūtau kawenga ki te tatau i te taumaha o te hua i roto i te pūwero pauna. Kei te mīhini pauna maha-upoko he tukatuka e tatau ana i te huinga pai rawa atu o ngā taumaha katoa e wātea ana hei whakatutuki i te taumaha e hiahiatia ana.

E mōhiotia ana ko te nui ake o ngā pane pauna kei runga i tō mīhini pauna maha-upoko ka tere ake te whakaputa huinga. Ka taea te whakaputa i ngā wāhanga pauna tika o tētahi hua i te wā kotahi. Kei te haere tonu te pauna kotahi-upoko whānui ki te whakatutuki i te taumaha e hiahiatia ana. Kāore e taea te tere rawa te tere whāngai kia tika ai. I te nuinga o te wā, ko te nui o ngā rauemi i roto i ia hopara ka whakatakotoria ki te 1/3 ki te 1/5 o te taumaha whāinga.

I te wā e tatauhia ana te pauna whakakotahi, ko ngā whakakotahitanga hapa anake ka whakamahia. Ka taea te whakatau tata i te maha o ngā pane e whai wāhi ana ki tētahi whakakotahitanga mā te whakamahi i te tātai: n=Cim=m! / I! (m - I)! Ko m te tapeke o ngā peke pauna i roto i te whakakotahitanga, ā, ko I te maha o ngā pākete e whai wāhi ana. I te nuinga o te wā, i te tipu haere o m, I, me te maha o ngā whakakotahitanga ka taea, ka piki ake te whiwhi hua pai.

Ka taea te whakarite i tō pauna maha-upoko me ngā tāpiritanga kōwhiringa kia pai ai te mahi me ngā momo hua. Ko te pūwero wā te mea tino noa o ēnei mahi. Ka kohia e te pūwero wā te hua kua tukuna mai i ngā pūwero pauna, ā, ka puritia kia tae rā anō ki te wā e tohutohu/tohu ana te mīhini tākai kia tuwhera. Kia tuwhera rā anō, kia kati rā anō te pūwero wā, e kore te pauna maha-upoko e tuku i tētahi hua mai i ngā pūwero pauna. Ka tere ake te tukanga mā te whakapoto i te tawhiti i waenga i te pauna maha-upoko me ngā taputapu tākai. Ko tētahi painga anō ko ngā pūwero whakakaha, e mōhiotia ana ko tētahi paparanga atu o ngā pūwero kua tāpirihia hei penapena i te hua kua paunatia kētia ki roto i te pūwero taumaha. Kāore tēnei hua e whakamahia ana i roto i te pauna, e whakanui ake ana i ngā huinga e tika ana mō te pūnaha, ā, e whakanui ake ana i te tere me te tika.
