taupū
pū - heap, stack, bundle
Hei tohu i te whakareatanga tāruarua o te tētahi tau. Ka whakanōhia te pū ki te koko whakarunga i te taha matau o te tau, ā, ko tāna, he tohu i te maha o taua tau e whakareatia ana. Hei tauira:
Mō te pūrua: 32 = 3 x 3 = 9
Mō te pūtoru: 53 = 5 x 5 x 5 = 125
Mō te pūwhā: 24 = 2 x 2 x 2 x 2= 16
Ko te 16 te pūrua o te 4.
Pūtorutia te 2, ka 8. 
He aha te pūtoru o te rua?
E toru ngā whakahuatanga o te taupū. Hei tauira, ko te 24 = 16:
Kia mataara:
I roto i te reo Ingarihi, ka whakamahia te kupu 'squared' hei kawe i te tikanga o te pūrua. Ka pōraruraru katoa te ākonga ina whakamahia te kupu 'tapawhā' (mō te squared) i roto i ngā akoranga reo Māori. Ka pōraruraru nā te mea e whakamahia ana te kupu 'tapawhā', engari he '2' kē te tohu.
