Takenga mai:

pū - heap, stack, bundle

Whakamārama:

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

A symbol for the repeated multiplication of a number. The power is shown at the top right hand corner of the number, and indicates how many of that number are being multiplied together.

Tauira kōrero:

Ko te 16 te pūrua o te 4.
Pūtorutia te 2, ka 8.
He aha te pūtoru o te rua?

Whakamārama atu anō:

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.

Anei ngā tau pūrua tae atu ki te 102: Anei ngā tau pūtoru tae atu ki te 103:
12 = 1 = 1 x 113 = 1 = 1 x 1 x 1
22 = 4 = 2 x 223 = 8 = 2 x 2 x 2
32 = 9 = 3 x 333 = 27 = 3 x 3 x 3
42 = 16 = 4 x 443 = 64 = 4 x 4 x 4
52 = 25 = 5 x 553 = 125 = 5 x 5 x 5
62 = 36 = 6 x 663 = 216 = 6 x 6 x 6
72 = 49 = 7 x 773 = 343 = 7 x 7 x 7
82 = 64 = 8 x 883 = 512 = 8 x 8 x 8
92 = 81 = 9 x 993 = 729 = 9 x 9 x 9
102 = 100 = 10 x 10 103 = 1,000 = 10 x 10 x 10
