Hoʻomaka ke aʻo ʻana i ka makemakika me nā helu kūlohelohe a me nā hana me lākou. Akā i ka intuitively ua ʻike nui mākou mai ka wā kamaliʻi. Ma kēia ʻatikala, e kamaʻāina mākou i ke kumumanaʻo a aʻo i ke kākau ʻana a me ka haʻi pololei ʻana i nā helu paʻakikī.
Ma kēia hoʻolaha, e noʻonoʻo mākou i ka wehewehe ʻana o nā helu kūlohelohe, papa inoa i kā lākou waiwai nui a me nā hana makemakika i hana ʻia me lākou. Hāʻawi pū mākou i kahi papa me nā helu kūlohelohe mai 1 a 100.
Ka wehewehe ʻana o nā helu maoli
Pūnaewele - ʻo ia nā helu āpau a mākou e hoʻohana ai i ka helu ʻana, e hōʻike i ka helu serial o kekahi mea, etc.
moʻo kūlohelohe ʻo ia ke kaʻina o nā helu kūlohelohe a pau i hoʻonohonoho ʻia ma ka papa piʻi. ʻO ia hoʻi, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, etc.
Ka hoʻonohonoho o nā helu kūlohelohe a pau hōʻike ʻia penei:
N={1,2,3,…n,…}
N he hoʻonohonoho; he palena ole, no ka mea, no kekahi n he heluna nui aku.
ʻO nā helu kūlohelohe nā helu a mākou e hoʻohana ai no ka helu ʻana i kekahi mea kikoʻī, hiki ke ʻike.
Eia nā helu i kapa ʻia: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, etc.
ʻO ka moʻo kūlohelohe he kaʻina o nā helu kūlohelohe a pau i hoʻonohonoho ʻia ma ke ʻano piʻi. Hiki ke ʻike ʻia ka haneli mua ma ka pākaukau.
ʻAno maʻalahi o nā helu maoli
- ʻAʻole helu maoli nā huahelu ʻole, ʻaʻole-integer (fractional) a me nā helu ʻino. No ka laʻana:-5, -20.3, 3/7, 0, 4.7, 182/3 a oi
- ʻO ka helu maoli liʻiliʻi loa he hoʻokahi (e like me ka waiwai ma luna).
- No ka pau ʻole o ka moʻo kūlohelohe, ʻaʻohe helu nui loa.

He aha nā helu kūlohelohe?
Ka helu decimal o kahi helu maoli
Ma ke kula, hele mākou i ke kumuhana o nā helu kūlohelohe i ka papa 5, akā ʻo ka mea ʻoiaʻiʻo, hiki i nā mea he nui ke maopopo iā mākou ma mua. E kamaʻilio kākou e pili ana i nā lula koʻikoʻi.
Hoʻohana mau mākou i nā helu: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9. Ke kākau ʻana i kekahi helu maoli, hiki iā ʻoe ke hoʻohana i kēia mau helu me ka ʻole o nā hōʻailona ʻē aʻe. Kākau mākou i nā helu i kēlā me kēia ma ka laina mai ka hema a i ka ʻākau, me ke kiʻekiʻe like.
Nā laʻana o ke kākau pololei ʻana o nā helu kūlohelohe: 208, 567, 24, 1467, 899112. Hōʻike kēia mau laʻana iā mākou he ʻokoʻa ke kaʻina o nā helu a hiki ke hana hou ʻia kekahi.
ʻO 077, 0, 004, 0931 nā laʻana o ka helu kuhi hewa ʻana o nā helu kūlohelohe, no ka mea, aia ka zero ma ka hema. ʻAʻole hiki ke hoʻomaka ka helu mai ka ʻole. ʻO kēia ka hōʻike decimal o kahi helu maoli.
Ka manaʻo nui o nā helu maoli
Lawe nā helu kūlohelohe i ke ʻano quantitative, ʻo ia hoʻi, hana lākou ma ke ʻano he mea hana no ka helu ʻana.
E noʻonoʻo ʻoe he maiʻa 🍌 i mua o mākou. Hiki iā mākou ke hoʻopaʻa ʻike mākou i 1 maiʻa. I kēia hihia, heluhelu ʻia ka helu maoli 1 ma ke ʻano he "hoʻokahi" a i ʻole "hoʻokahi".
Akā ʻo ka huaʻōlelo "unit" he manaʻo ʻē aʻe: hiki ke noʻonoʻo ʻia ma ke ʻano holoʻokoʻa. Hiki ke kuhikuhi ʻia kahi ʻāpana o kahi pūʻulu e kahi ʻāpana. No ka laʻana, ʻo kēlā me kēia lāʻau mai kahi pūʻulu lāʻau he ʻāpana, ʻo kēlā me kēia lau mai kahi pūʻulu lau he ʻāpana.
E noʻonoʻo ʻoe he 2 maiʻa 🍌🍌 i mua o mākou. Heluhelu ʻia ka helu maoli 2 ma ke ʻano he "ʻelua". Eia hou, ma ka hoohalike ana:
🍌🍌🍌 3 mau mea (“ʻekolu”)
🍌🍌🍌🍌 4 mau mea (“ʻehā”)
🍌🍌🍌🍌🍌 5 mau mea (“lima”)
🍌🍌🍌🍌🍌🍌 6 mau mea ("ʻeono")
🍌🍌🍌🍌🍌🍌🍌 7 mau mea ("ʻehiku")
🍌🍌🍌🍌🍌🍌🍌🍌 8 mau mea (“ʻewalu”)
🍌🍌🍌🍌🍌🍌🍌🍌🍌 9 mau mea (“eiwa”)
ʻO ka hana nui o kahi helu kūlohelohe e hōʻike i ka helu o nā mea.
Inā pili ka moʻolelo o kahi helu me ka helu 0, a laila ua kapa ʻia ʻo "zero". E hoʻomanaʻo ʻaʻole ʻo ka zero he helu kūlohelohe, akā hiki ke manaʻo ʻia he haʻalele. ʻAʻohe mea ʻole.
Hoʻokahi-helu, ʻelua-helu a me ʻekolu-helu helu maoli
ʻO ka huahelu kūlohelohe hoʻokahi he helu i loaʻa hoʻokahi hōʻailona a hoʻokahi huahelu. ʻEiwa huahelu maoli: 1, 2, 3, 4, 5, 6, 7, 8, 9.
ʻO nā huahelu kūlohelohe ʻelua mau hōʻailona ʻelua. Hiki ke helu hou a ʻokoʻa paha nā helu. No ka laʻana: 88, 53, 70.
Inā he ʻeiwa a me hoʻokahi mau mea i hoʻonohonoho ʻia, a laila ke kamaʻilio nei mākou e pili ana i 1 ʻumi ("hoʻokahi kakini") o nā mea. Inā hoʻokahi ʻumi a hoʻokahi hou aku, a laila, loaʻa iā mākou he 2 ʻumi (“ʻelua ʻumi”) a pēlā aku.
ʻO ke kumu, ʻo ka helu helu ʻelua he pūʻulu o nā helu helu hoʻokahi, kahi i kākau ʻia ai kekahi ma ka ʻākau a ʻo kekahi ma ka hema. Hōʻike ka helu ma ka hema i ka helu o nā ʻumi ma ka helu maoli, a ʻo ka helu ma ka ʻākau e hōʻike ana i ka helu o nā ʻāpana. He 90 mau huahelu maoli elua.
ʻO nā huahelu kūlohelohe ʻekolu mau huahelu me nā huahelu ʻekolu a me nā huahelu ʻekolu. No ka laʻana: 666, 389, 702.
ʻO ka haneli he ʻumi. Hoʻokahi haneli a me kekahi haneli - 2 haneli. E hoʻohui hou aku i 3 mau haneli.
Penei ke kākau ʻia ʻana o ka helu helu ʻekolu: kākau ʻia nā helu kūlohelohe kekahi ma hope o kekahi mai ka hema a i ka ʻākau.
Hōʻike ka huahelu hoʻokahi ʻākau i ka helu o nā ʻāpana, ʻo ka mea aʻe e hōʻike i ka helu o nā ʻumi, a ʻo ka mea hema loa e hōʻike i ka helu o nā haneli. Hōʻike ka helu 0 i ka nele o nā ʻāpana a i ʻole nā ʻumi. No laila, ʻo 506 he 5 haneli, 0 ʻumi a me 6 mau mea.
Hoʻohālikelike ʻia nā helu ʻehā, ʻelima, ʻeono a me nā helu kūlohelohe ʻē aʻe.
Helu kumu waiwai nui
ʻO nā huahelu kūlohelohe he ʻelua a ʻoi aku paha nā huahelu.
ʻO 1,000 he ʻumi haneri, ʻo 1,000,000 he tausani tausani, a ʻo ka piliona he tausani miliona. Hoʻokahi tausani miliona, e noʻonoʻo wale! ʻO ia hoʻi, hiki iā mākou ke noʻonoʻo i kēlā me kēia helu kumu waiwai nui ma ke ʻano he pūʻulu o nā helu kūlohelohe hoʻokahi.
Eia kekahi laʻana, aia ka 2 873 206: 6 ʻāpana, 0 ʻumi, 2 haneli, 3 tausani, 7 ʻumi kaukani, 8 haneli tausani a me 2 miliona.
Ehia mau helu maoli?
Hoʻokahi-helu 9, ʻelua-helu 90, ʻekolu-helu 900, etc.
Nā waiwai o nā helu maoli
Ua ʻike mua mākou i nā hiʻohiʻona o nā helu kūlohelohe. A i kēia manawa e kamaʻilio mākou e pili ana i kā lākou mau waiwai.
Wehewehe ʻana o kahi helu maoli
ʻO nā helu kūlohelohe nā helu a mākou e hoʻohana ai no ka helu ʻana i kekahi mea kikoʻī, hiki ke ʻike.
Eia nā helu i kapa ʻia: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, etc.
ʻO ka moʻo kūlohelohe he kaʻina o nā helu kūlohelohe a pau i hoʻonohonoho ʻia ma ke ʻano piʻi. Hiki ke ʻike ʻia ka haneli mua ma ka pākaukau.
Nā hiʻohiʻona o nā helu maoli
ʻO ka helu maoli liʻiliʻi loa: hoʻokahi (1).
Helu kūlohelohe nui loa: ʻaʻole i loaʻa. He palena ʻole ka moʻo kūlohelohe.
Ma ka moʻo kūlohelohe, ʻoi aku ka nui o kēlā me kēia helu ma mua o ka helu ma mua: 1, 2, 3, 4, 5, 6, 7, etc.
ʻO ka hoʻonohonoho o nā helu kūlohelohe a pau e hōʻike pinepine ʻia e ka leka Latin N.

Nā waiwai o nā helu maoli
Ua ʻike mua mākou i nā hiʻohiʻona o nā helu kūlohelohe. A i kēia manawa e kamaʻilio mākou e pili ana i kā lākou mau waiwai.
- pūʻulu o nā helu kūlohelohe ʻaʻohe palena a hoʻomaka mai hoʻokahi (1)
- hahai ʻia kēlā me kēia helu maoli e kekahi, ʻoi aku ia ma mua o ka helu ma mua e 1

Helu helu maoli a me ka waiwai o ka huahelu
E hoʻomanaʻo ʻo ke kūlana i kū ai ka huahelu ma ka moʻolelo o ka helu ma muli o kona waiwai. No laila, no ka laʻana, aia ka 1123: 3 ʻāpana, 2 ʻumi, 1 haneli, 1 tausani. I ka manawa like, hiki iā mākou ke hana ʻokoʻa a ʻōlelo ʻia i loko o kahi helu 1123, aia ka helu 3 i loko o nā huahelu, 2 i nā huahelu ʻumi, 1 i nā huahelu haneli, a ʻo 1 ka waiwai o nā tausani. huahelu.
ʻO ka huahelu ʻo ke kūlana, kahi o ka huahelu ma ka hōʻailona o kahi helu maoli.
Loaʻa i kēlā me kēia māhele kona inoa ponoʻī. Aia nā huahelu koʻikoʻi ma ka hema, a ʻo nā huahelu liʻiliʻi loa ma ka ʻākau. No ka hoʻomanaʻo wikiwiki, hiki iā ʻoe ke hoʻohana i kahi papaʻaina.
Pili mau ka helu o nā huahelu i ka helu o nā huahelu i ka helu. Aia i kēia papa nā inoa o nā huahelu a pau no ka helu he 15 mau huaʻōlelo. He mau inoa nō nā huahelu ma lalo nei, akā ʻaʻole hoʻohana ʻia.
ʻO ka huahelu haʻahaʻa (liʻiliʻi liʻiliʻi loa) o ka helu kūlohelohe i helu ʻia ʻo ka huahelu ʻāpana.
ʻO ka huahelu kiʻekiʻe loa (kiʻekiʻe) o ka helu kūlohelohe nui, ʻo ia ka huahelu e pili ana i ka huahelu hema loa i ka helu i hāʻawi ʻia.
Ua ʻike paha ʻoe i nā puke haʻawina e kau pinepine i nā wahi liʻiliʻi i ke kākau ʻana i nā helu helu lehulehu. Hana ʻia kēia i maʻalahi ka heluhelu ʻana i nā helu kūlohelohe. A eia kekahi - e hoʻokaʻawale i nā papa helu like ʻole.
ʻO ka papa he pūʻulu o nā huahelu i loaʻa nā huahelu ʻekolu: ʻāpana, ʻumi a me nā haneli.
Pūnaehana helu decimal
Ua hoʻohana ka poʻe i nā manawa like ʻole i nā ʻano kākau helu. A loaʻa i kēlā me kēia ʻōnaehana helu kona mau lula a me nā hiʻohiʻona.
ʻO ka ʻōnaehana helu decimal ka ʻōnaehana helu maʻamau i hoʻohana ʻia nā helu he ʻumi e kākau i nā helu: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9.
Ma ka ʻōnaehana decimal, pili ka waiwai o ka huahelu hoʻokahi i kona kūlana ma ka notation o ka helu. No ka laʻana, ʻo ka helu 555 he ʻekolu mau huahelu like. Ma kēia helu, ʻo ka huahelu mua mai ka hema mai ʻelima haneli, ʻo ka lua - ʻelima mau ʻumi, a ʻo ke kolu - ʻelima mau ʻāpana. No ka mea e pili ana ka waiwai o ka huahelu i kona kūlana, ua kapa ʻia ka ʻōnaehana helu decimal.
Ninau no ka hoao ana iho
ʻEhia mau helu kūlohelohe hiki ke kaha ʻia ma ka ray coordinate ma waena o nā kiko me nā hoʻonohonoho:
