Mahele ma 'Aʻohe: no ke aha mai?

Ke kanana 'pāpā ma ka mahele ma ka' Aʻohe ua kau a hiki i Junior kiʻekiʻe kula. Children pele mai manaʻo e pili ana i kona kumu, akā, ma ka ike maopopo, e ike i ke kumu i kekahi mea ua hookapuia, a me ia mea hana hoihoi a me ka maikaʻi kēia.

makemakika ana

Makemakika ana, a i ao aku i ke kula, kaiʻewaʻewa i ka hua'ōlelo o ka makemakika. Ka mea, hoʻomaopopo piha wale elua o kēia mau hana - hou a me ka multiplication. Ka mea, e hookomoia ma ka manaʻo o ka iho, a me nā mea a pau e hana me ka nui kekahi aoao ai kekahi ka i ka nānā 'ana ma luna o kēia mau. Oia hoi, he mea hiki ole i wale i ka puunaue ma Aʻohe, akā, i ka puunaue nui.

Subtraction a me ka mahele

He aha Ka nalowale i ke koena o ka hana? Hou, i ke kula ua 'ike nui ia, no ka laʻana, unuhi eha mai ka ehiku - laila lawe ehiku chocolates, eha o ia ai, a helu i ka poʻe i koe. Akā, ka makemakika , aole ia i hoʻoponopono i ka pilikia o ka ai ono loa a me ka laulā, ike ia pau okoa. No ia mea, mea wale nō hou, ka mea, i ka mooolelo o ka 7 - 4 = ka helu i o ka huina o ka helu 4 E e like no 7. I mea, no ka mathematicians, 7 - 4 - ua shorthand helu kaulike m + 4 = 7. kēia mea,ʻaʻole he subtraction, akā, i ka pilikia - e 'imi i ka helu i oe pono e waiho ma kahi o ka m.

ʻO ia pili ana i ka mahele me ka multiplication. Mahele ana he umi i elua, mladsheklassnikov hoolakolako mai he umi candies i loko o nā like puʻu. Mathematician ia lakou nei ke ike helu kaulike: 2 · m = 10.

A ka mea i akaka ke kumu ia mea 'ino ai mahele ma' Aʻohe: ia mea wale ole. Record 6: 0 e e huli i loko o ka helu kaulike 0 · He m = 6. I na olelo e ae, e makemake e huli i ka helu i hiki ke hoonuiia ka 'Aʻohe a kiʻi 6. Akā, ua ike i ka multiplication ma Aʻohe manawa e hāʻawi mai' Aʻohe. 'O kēia ka nui waiwai o ka' Aʻohe.

Pela, aia no he mea me ka helu ana, hoonui ma 'Aʻohe, e haawi aku i kekahi helu'ē aʻe ma mua o' Aʻohe. No laila, i kēia helu kaulikeʻaʻohe pāʻoihana, aole hoi he mea helu, i makemake e correlated me ka mooolelo o ka 6: 0,ʻo ia hoʻi, ka mea, aole ia i hana pono. Ma kona senselessness a me ka olelo i ka papa aku i ke ku e ana 'Aʻohe.

Ua 'Aʻohe i puunaueia ma ka' Aʻohe?

He mea hiki ke 'Aʻohe puunaueia e Aʻohe? Ka helu kaulike 0 · He m = 0 mea,ʻaʻole paʻakikī, a hiki e ia e like me ka m loa 'Aʻohe a kiʻi 0 · 0 = 0. A laila, 0: 0 = 0? Akā, inā, no ka laʻana, lawe no ka m pa alima, i loaa 0 · 1 = 0. Ua hiki e ia no ka m me ka mau kekahi i makemake ka helu a me ka puunaue ma Aʻohe, a me ka hopena, e noho i ka ia: 0: 0 = 9, 0: 0 = 51, a no laila, ma.

Pela, ma keia helu kaulike, e hiki ke hookomo i kekahi helu o ka loa, a me 'oe hiki ole koho kekahi, he mea hiki ole i ka hoʻoholo' ana he nui loa i koho moolelo 0: 0. I mea, no hoi, aole e hana i keia mooolelo ke aloha, a me ka puunaue ma 'Aʻohe mea no ole: ka mea, i puunaueia e ma ia ia iho.

I mea nui ka hiʻona o ka mahele hana, i mea, i ka multiplication, a me ka pili i ka helu mea 'Aʻohe.

I ka ninau i koe: no ke aha la hiki ole puunaue ma Aʻohe, akā, ka mea hiki ke deducted? Mākou ke i aku nei au i keia makemakika hoʻomaka me keia hana hoihoi pilikia. E imi i ka pane, e pono e aʻo i ka 'olelo makemakika ka wehewehena o ka laulā e puhi ia, a hālāwai me ka hana ma luna o ia mau mea. No ka laʻana, he mea ole wale na mea, akā, i luna 'nui, i ke ku e i kekahi, mai kaʻike mau mahele. Ua ua i komo i loko o ke kula laulā maʻamau, akā, i ke kulanui haʻi'ōlelo ma ka makemakika e hoʻomaka ana me keia.
