KA PILI
Hoʻoholo piha ʻia ka puzzle e kona lālani lalo.
Ke hahai nei i nā helu i luna, loaʻa iā mākou ʻelua mau palena koke ma ka lālani lalo. Pono nā helu ʻelua ma ka ʻaoʻao hema loa ma ka lālani lalo e hoʻohui i ka 6, no laila he 1 + 5 a i ʻole 2 + 4. Eia kekahi, ʻekolu manawa o ka huina o nā helu waena ʻelua, me ka huina o nā helu kihi ʻelua, pono he 24.
ʻEhā mau hāʻawina hiki ke loaʻa mai ka ʻaoʻao hema o ka lālani lalo. I kēlā me kēia hihia, ʻike mākou e hāʻawi ka ʻaoʻao ʻākau i ke koena me ka hoʻohana ʻana i 3 manawa o kona helu waena me 1 manawa o kona helu kihi.
Hihia 1: (1 5) e hāʻawi ana i ka 1 + 3 x 5 = 16. Pono mākou i 8 hou aʻe mai ka ʻaoʻao ʻākau. ʻAʻole hiki ke hana ʻia kēlā me ka ʻole o ka pāpālua ʻana i nā helu.
Hihia 2: (5 1) e hāʻawi ana i ka 5 + 3 x 1 = 8. Pono mākou i 16 hou aʻe mai ka ʻaoʻao ʻākau. Hiki i kēia ke hana me (3 7) a i ʻole (2 10). Inā ʻo ka lalo (5 1 3 7), aia kahi pālua. Inā ʻo ka lalo (5 1 2 10), hana ia!
Hihia 3: (2 4) e hāʻawi ana i ka 2 + 3 x 4 = 14. Pono mākou i 10 hou aʻe mai ka ʻaoʻao ʻākau. Hiki i kēia ke hana me (3 1) a i ʻole (1 7). (inā ʻo ka lalo (2 4 3 1), aia kahi pālua. Inā ʻo ka lalo (2 4 1 7), hana ia!
Hihia 4: (4 2) e hāʻawi ana i ka 4 + 3 x 2 = 10. Pono mākou i 14 hou aʻe mai ka ʻaoʻao ʻākau. Hiki i kēia ke hana me (3 5) a i ʻole (1 11). Inā ʻo ka lalo (4 2 3 5), aia kahi pālua. Inā ʻo ka lalo (4 2 1 11), hana ia!
