Ka neke Matatika i te āwangawanga piringa ki te āwangawanga pokapū, me te reira ka riro i te kaupapa o te rangahau.
I roto i te ao mamati, matatika-neke atu i te utu-ka riro i te herenga ngoi i runga i kairangahau. E te, i roto i te heke mai, ka uaua tatou iti ki te aha e taea te mahi me te ake ki te mea kia meatia. Ka rite ki taua tupu, tatari ahau e ka whanake te huarahi ture-e hāngai ana o pūtaiao pāpori me te huarahi ad-hoc o pūtaiao raraunga ki te tahi mea rite te mau parau tumu-e hāngai ana whakatata whakaahuatia i roto i te Chapter 6. tatari ano ahau e rite matatika riro he rangahau atu rongonui herenga, ka riro te reira i te kaupapa o te rangahau iho. I roto i nui te ara ano e inaianei lī'oa kairangahau pāpori wa, me te pūngao ki te whakawhanake tikanga hou e taea ai tata iti me te tika atu, tatari ahau e ka mahi ano matou ki te whakawhanake i ngā tikanga e te hunga ake matatika kawenga. Tenei huringa ka tupu kore noa no te mea tiaki kairangahau e pā ana ki matatika hei mutunga, engari ano no te tiaki ngā kairangahau e pā ana ki matatika rite ki te tikanga ki te whakahaere rangahau pāpori.
He tauira o tenei au ko te rangahau i runga i tūmataiti pārōnaki (Dwork 2008) . A feruri na e, e hiahia ana ngā pūkete hauora me kairangahau mo te tauira, kua ngā he hōhipera ki mahino nga tauira i roto i taua raraunga. Differentially hātepe tūmataiti taea iwi ki te uiui i te pūkete hauora ki te ako e pā ana ki ngā tauira töpü (hei tauira, te iwi nei kaipaipa e pea atu ki te whai pukupuku) te faaiti i te mōrea o tetahi mea e pā ana ki te āhuatanga o tetahi takitahi ngā akoranga. Whakawhanake enei ahua o hātepe tūmataiti-tiaki kua meinga hei wāhi mātātoa o te rangahau; kite Dwork and Roth (2014) mo te maimoatanga pukapuka-roa. Ko te tūmataiti pārōnaki he tauira o te hapori rangahau tango he wero matatika, tahuri te reira ki te kaupapa rangahau, me ka hanga te ahunga whakamua i runga i te reira. Ko te tauira e whakaaro ahau piki tatou e kite i roto i te tahi atu wāhanga o te rangahau pāpori tenei.
Ka rite ki te kaha o kairangahau, he maha i roto i te mahi tahi ki te kamupene me te kāwanatanga, tonu ki te whakapiki ake i, ka riro te reira piki uaua ki te karo i ngā take matatika matatini. Kua riro te reira toku wheako e tiro maha pūtaiao pāpori me pūtaiao raraunga enei take matatika rite te repo ki te kia karohia. Ko, whakaaro ahau e meinga e te pare piki Mäori rite te rautaki. Matou, pera me te hapori, ka taea e anake te whakatutuki i ēnei raruraru, ki te peke tatou i roto i, me te rutu ia ratou ki te auahatanga me te kaha e te tono tatou ki te tahi atu mau fifi rangahau.
