4

4 (ʻehā) he helu maʻamau ma waena o ka 3 a me ka 5. He helu pālua ia (2 × 2 = 4), a he helu ʻoi (composite number). Ma ka moʻomeheu Hawaiʻi, he koʻikoʻi ka helu ʻehā no nā kūkulu ʻehā o ka honua a me nā akua nui ʻehā: Kāne, Kū, Lono, a me Kanaloa. Ma nā moʻolelo kahiko o ʻĀkia Hikina, kū ka 4 ma ke ʻano he helu pōʻino, no ka mea, like ke kani o "4" me ka huaʻōlelo no ka make ma kēia mau ʻōlelo.

Ma ka makemakika, aia ʻehā hana maʻamau: ka huinahelu (+), ka lawenahelu (−), ka hoʻonui (×), a me ka māhele (÷). He helu pālua ka 4, a he helu piha, a he helu Harshad. ʻO ia kekahi o nā helu Harshad a pau ʻehā.

Nā māhele

He helu māhele ka 4 ma o ka 1, 2, a me ka 4. He helu pālua maikaʻi loa ia, no ka mea, hiki ke māhele ʻia e ka 2 hoʻokahi manawa wale nō (4 = 2 × 2).
