Maliʻa, ua haʻohaʻo ʻoe i ke ʻano o »ʻoi aku i«, A pehea e hoʻokaʻawale ai iā ia mai nā hōʻailona makemakika ʻē aʻe. ʻĀ, no ka ʻike ʻole pehea e ʻike ai, he mea maʻamau a hiki i ka wā e kamaʻāina mākou me lākou. No laila, i loko o kēia ʻatikala hoihoi a me ka ʻikepili e wehewehe mākou i nā mea āpau e pili ana i kēia ʻelele o ke kaulike ʻole. E leʻaleʻa ia !.

ʻoi aku-i-1

ʻOi aku ia

I ka makemakika, hoʻohana ʻia nā hōʻailona e hoʻokaʻawale i nā helu i ʻoi aku ka nui a i ʻole nā ​​mea ʻē aʻe. I kēia hihia, ua kāhea ʻia nā hōʻailona ʻelua: ʻoi aku ma mua o ka hōʻailona (>), a emi ma mua o ka hōʻailona (<). He hōʻike ko kēlā me kēia mea i ke ʻano o ka pua a i ʻole V i hoʻohuli ʻia, e hōʻike ana i ka puka nui loa i ka helu nui loa, aia mau ma ka ʻaoʻao hema.

Nā laʻana a me nā pilikia

Ke ʻike mākou i kekahi mau helu, hiki iā mākou ke hoʻomaopopo maʻalahi ʻo wai ka mea nui a ʻo wai ka mea liʻiliʻi. ʻO kahi laʻana: Loaʻa iā mākou kēia mau helu a pono mākou e ʻike i ka nui a me ka liʻiliʻi: 1,3 a me 5.

I kēia hihia, ʻike mākou ʻo ka helu 5 ka nui loa o nā mea āpau, ukali ʻia e 3, a laila ka mea liʻiliʻi loa o 1. Akā, i mea e hōʻuluʻulu ai i kēia kaʻina holoʻokoʻa, hoʻomaka mākou e hoʻohana i ka hōʻailona like: ka nui>), penei: 5> 3> 1.

He mea mau ia i nā kula aia kekahi huikau i ka manawa o ke kākau ʻana, akā ʻaʻohe mea e hoʻomaʻamaʻa ʻia e ka hoʻomaʻamaʻa. Inā he paʻakikī me kēia mau hōʻailona, ​​hiki ke hana ʻia nā haʻawina calligraphy a i ʻole ka hana ma waena o nā kiʻi ʻokoʻa.

Akā, nui nā haumāna i ka paʻakikī ke hiki mai i nā helu nui aku. Hana ʻia kēia, no ka mea ʻaʻole ʻokoʻa ka hoʻokaʻawale o nā anakuhi, a ʻo kēia ka hopena i ka ʻike ʻole i ka nui e lawelawe ʻia.

ʻO kahi laʻana: Loaʻa iā mākou nā mea i lalo: 106.781 a me 105.450.

I kēia hihia, 106.781 (heluhelu: hoʻokahi haneli ʻeono tausani, ʻehiku haneli kanawalukumamakahi) a me 105.450 (heluhelu: hoʻokahi haneli ʻelima tausani, ʻehā haneli kanalima). I kēia ala, ʻike pehea e hoʻokaʻawale ai i nā anakuhi a pehea e heluhelu ai i kēlā me kēia, e ʻike ana mākou i ka mea ʻoi aku ka nui.

106.781 ʻoi aku ma mua o 105.450. No laila, ke hoʻohana nei i ka ʻoi aku ma mua o ka hōʻailona, pono mākou e kākau i ke ala penei: 106.781> 105.450.

He mea nui e aʻo pololei ʻia nā anakuhi, i mea e hoʻokaʻawale ai i ka mea nui mai ka mea liʻiliʻi ma mua.

Ma ka ʻaoʻao hea wau e kau ai i ka mea ʻoi aku ma mua o ka hōʻailona?

E kuhikuhi mau kēia hōʻailona i ka wehe nui loa i ka nui i ʻoi aku, kuhikuhi mau i ke kiʻi me ka nui nui i ka ʻaoʻao hema.

I mea e hōʻalo ai i ka huikau i ka manawa o ke kākau ʻana, pono e hoʻomanaʻo inā inā e kuhikuhi ka wehe i ka ʻaoʻao ʻākau (ma ke ʻano like e hōʻike ʻoi aku ka nui ma mua o), akā i kēia hihia, ʻo ka hōʻailona laulā o ka hoʻoikaika kino e hōʻike ana ma lalo o.

E hoʻohana mākou i nā mea i lalo e like me kahi laʻana, a ʻike i ka ʻoi aku ma mua o ka hōʻailona o nā mea ʻē aʻe, i nā helu āpau: 30, 15, 35, 100, 120.

Nā hopena: 120> 100> 35> 30> 15. Hiki iā mākou ke ʻike i ka ʻoi aku ma mua o ka hōʻailona, he puka nui i ka nui i ʻoi aku ma mua o ka nui ʻē aʻe, e hōʻailona ana i ka ʻokoʻa ma waena o lākou. Kāhea ʻia kēia he hōʻailona kaulike (no ka mea ʻaʻohe kaulike nā helu ʻelua. ʻO ia hoʻi, ʻoi aku kekahi ma mua o kekahi.)

Inā mākou e hoʻohālikelike me ka emi ma mua o ka hōʻailona, hiki iā mākou ke nānā i ka wehe i ka ʻaoʻao ʻākau, akā i kēia hihia, e nānā mākou e kuhikuhi mākou i ka nui ma ka ʻaoʻao hema, e hōʻike ana he mea ʻoi aku ia ma mua o ka nui e ukali ana.

E lawe mākou i nā helu a mākou i hoʻohana ai ma ke ʻano he laʻana ma luna, akā e hōʻike ana mākou i ka mea liʻiliʻi ma mua o ka hōʻailona, ​​i kēia manawa:

15 <30 <35 <100 <120. Hiki iā mākou ke ʻike i ka wehe i ka ʻaoʻao ʻākau, akā ke kahakaha nei mākou mai ka ʻaoʻao hema ka liʻiliʻi liʻiliʻi ma mua o ka mea e ukali nei. No laila, hiki iā mākou ke ʻōlelo: 15 ma lalo o 30, 30 ma lalo o 35, 35 ma mua o 100, a 100 ma mua o 120.

I mea e maʻalahi ai iā ʻoe e hoʻomanaʻo i nā hōʻailona, ​​ʻike paha ʻoe i ka ʻaoʻao e hōʻike ana i ka nui ma mua o ka liʻiliʻi. Ma kēia ala e hiki ai iā ʻoe ke hoʻokaʻawale koke i nā hōʻailona ke ʻike ʻoe iā ʻoe iho me ka nui a i ʻole nā ​​liʻiliʻi. He maʻalahi ia, ʻeā?

Nānā: he mea nui e aʻo e heluhelu i ka hōʻailona kaulike me nā nui, i hiki ai iā ʻoe ke hoʻomaopopo maikaʻi i nā kiʻi e ʻokoʻa a no ke aha.

oi aku i

 

He moʻolelo nui

Ua ʻike ʻia kēia mau hōʻailona no ka manawa mua ma ka makahiki 1631, i loko o ka puke e pili ana i ka hoʻoponopono ʻana i nā hoʻohālikelike algebraic na Thomas Harriot: (he makemakika Pelekane a me ka kilo hōkū). ʻOiaʻiʻo, ʻo ia ka makuakāne o nā hōʻailona makemakika.

ʻAʻole wale ʻo ia i waiho i kahi hoʻoilina nui ma nā wahi o optics a me ka refraction o ke kukui ma nā wahi like ʻole, akā ua hiki nō hoʻi iā ia ke hana i nā ʻano like ʻole o ka hōʻailona ʻana i nā ʻano makemakika he nui. ʻO ka mea kānalua e kōkua nui iā mākou i kēia lā.

Ma muli o ka mahalo i kēia mau hōʻailona (ʻoi aku ma mua o - ʻoi iki, ma waena o nā mea ʻē aʻe), hiki iā mākou ke hana i nā ʻokoʻa wikiwiki ke kamaʻilio e pili ana i nā nui i nā helu.

Nā hana a me nā ala e hoʻomaʻamaʻa ai

Hoʻomaʻamaʻa A: 1.000 a me 500. I kēia hihia, pono ʻoe e nīnau iā ʻoe iho, He aha ka nui loa ma aneʻi? Pololei! 1.000 ʻoi aku ka nui. I kēia manawa pono ʻoe e kākau ia me ka hōʻailona kūpono.

1.000> 500: ʻOi aku ka nui o ka tausani ma mua o ʻelima haneli. (ʻOi aku ka nui o 1.000 ma mua o 500).

Hana B: 345, 250 a me 620. Pono ʻoe e ʻike pehea e hoʻokaʻawale ai i nā nui a heluhelu pono iā lākou i hiki ai iā ʻoe ke hoʻokaʻawale i ke kiʻi kiʻekiʻe aʻe mai nā mea ʻē aʻe.

ʻO 620 ka nui loa. Hahai ʻia e 345 a ʻo ka hope, ʻo ka mea liʻiliʻi he 250. A laila hoʻomau mākou e kākau iā lākou me ka hōʻailona ʻoi aku ma mua o:

620> 345> 250: ʻEono haneli iwakālua i ʻoi aku ma mua o ʻekolu haneri kanahākumamālima, a ʻoi aku ka nui o ʻekolu haneri kanahākumamālima ma mua o ʻelua haneli a me kanalima. (620 ʻoi aku ma mua o 345, a ʻo 345 ʻoi aku ma mua o 250).

Hana C) 1600> 1559: Hoʻokahi kaukani ʻeono haneli ka nui ma mua o hoʻokahi kaukani ʻelima haneli me kanalimakūmāiwa. (1600 ʻoi aku ma mua o 1559).

Nā hana D) 20 21: ʻoi aku ka iwakālua ma mua o iwakāluakūmākahi. (20 ma lalo o 21).

Kahakaha: E hoʻomanaʻo pono ʻoe e aʻo e heluhelu i nā nui, pono ia ʻoe e ʻike pehea e hoʻokaʻawale ai i nā kiʻi me ka pololei, pono ʻoe e hoʻopaʻanaʻau i ka hōʻailona nui o ka mea ʻōpio, a ʻo ka mea hope loa, he mea nui e kau ʻoe i ke kumu o ke kaulike ʻole o nā helu ʻelua. I kēia hihia, pono ʻoe e kākau i nā nui a wehewehe i ka hōʻailona pili.

E hoʻomanaʻo he paʻakikī a paʻakikī paha ka makemakika, pono wale nō i ka hana mau. Inā makemake ʻoe e hoʻomau i ke aʻo ʻana, a laila pono ʻoe e kipa i kēia loulou: Nā helu kūlohelohe.
