Tohu:

⁺

Takenga mai:

tau - number
tō - that of
runga - above

Whakamārama:

Ko ngā tau runga ake i te kore. He tau tōrunga te ⁺3, he tau tōrunga hoki te ⁺3 ½ me te ⁺3.25. Kāore i te rerekē te ⁺3 me te 3. I ētahi wā e whakaaturia ana te tohu ⁺, he wā anō kāore e whakaaturia.

The set of numbers above zero. The ⁺ sign is used to show a positive number, ⁺3, ⁺3 ½ and ⁺3.25 are all positive numbers. There is no difference between the numbers depicted by ⁺3 and 3. Sometimes the ⁺ sign is shown, other times it is not.

Tauira kōrero:

Tāpirihia te whā tōraro ki te rua tōrunga.
He tōrunga, he tōraro rānei te whiwhinga a Tiger Woods?
I te raumati, noho ai te paemahana ki ngā tau tōrunga.

Whakamārama atu anō:

Ko te whakahua tika i te ⁺5, ko te 'rima tōrunga'.

Ka whakaaturia ngā tau tōrunga ki te taha matau o te kore i te rārangi tau. Kāore he mutunga o ngā tau tōrunga (kāore hoki he mutunga o ngā tau tōraro):

Inā whakareatia tētahi tau tōrunga ki tētahi tau tōraro, he tau tōraro te otinga. Arā: 4 x ^-6 = ^-24

Koia nei tētahi tāpiritanga me tētahi tangohanga e whakaaturia ana ki te rārangi tau:
