Mmene angathetsere matsenga lalikulu (kalasi 3)? Madalitso kwa ophunzira

masamu masamu kulibe chiwerengero sangaganize. Aliyense wa iwo ndi wapadera njira zawo, koma chithumwa awo kwagona kuti njira n'kogwiritsa kubwera kwa mitunduyi ndi. Kumene, tingayese kuwathetsa, monga iwo amati, mwachisawawa, koma idzakhala nthawi yaitali kwambiri ndi pafupifupi munthu wabwino.

Nkhaniyi itithandiza kulankhula za wina wa zinsinsi izi, koma kukhala enieni - wa lalikulu matsenga. Tikatha kupenda mwatsatanetsatane mmene angathetsere lalikulu matsenga. 3 kalasi ya pulogalamu bwino, ndithudi, izo zimapita, koma mwina si aliyense anamvetsa kapena sanakumbukire.

Kodi chinsinsi ichi?

Magic lalikulu, kapena monga iwo ukutchedwa, zamatsenga - tebulo lomwe chiwerengero cha mizati ndi mizere ya yemweyo, ndipo iwo onse anadzazidwa ndi zithunzi zosiyana. Vuto lalikulu kwa ziwerengero kuchuluka kwa ofukula, yopingasa ndi opendekera kupereka phindu chomwecho.

Kuwonjezera lalikulu matsenga, palinso theka-zamatsenga. Amatanthauza kuti Uwerenge manambala koma yemweyo vertically ndi horizontally. Magic lalikulu "wamphamvu" kokha kukachitika kuti ntchito kudzaza manambala zachilengedwe mgwirizano.

Komabe pali chinthu monga ofananira matsenga lalikulu - ndi pamene mtengo wa ndalama za manambala awiri ndi wofanana, pa nthawi imene iwo anakonza symmetrically za pakati.

Ndi kofunika kudziwa kuti mabwalo angakhale kukula kulikonse kuwonjezera pa 2 ndi 2 lalikulu 1 1 amadziwikanso ankaona kuti zamatsenga, ngati zinthu zonse zitakwanira, ngakhale kuti imakhala nambala imodzi.

Choncho, ndi tanthawuzo tawerenga, tsopano tiyeni tikambirane za mmene angathetsere matsenga lalikulu. 3 maphunziro kalasi chodziwikiratu kufotokoza zonse monga zofunikila nkhaniyi.

Kodi njira zimene

Anthu amene amadziwa mmene angathetsere lalikulu matsenga (3 kalasi amadziwa), nthawi yomweyo kuti njira zitatu zokha, ndipo aliyense wa iwo ndi oyenera mabwalo zosiyanasiyana, koma sangaunyalanyaze njira chachinayi, ndiwo "mwachisawawa" . Ndipotu njira zina pali kuthekera kuti anthu osaphunzira komabe angathe kuthetsa chithunzi ichi. Koma njira imeneyi timapatula mu bokosi yaitali ndipo usapite ku kachitidwe ndi luso.

Yoyamba njira. Pamene lalikulu ali wosamvetseka

Njira imeneyi ndi yabwino kokha kwa kuthetsa chotero lalikulu lomwe lili wosamvetseka nambala ya maselo, mwachitsanzo, 3 ndi 3 kapena 5 pa 5.

Choncho, Mulimonsemo poyamba ayenera kupeza nthawi zonse zamatsenga. nambala iyi, amene analandira pamene kuchuluka kwa manambala diagonally, vertically ndi horizontally. Iwo masamu pogwiritsa ntchito njira:

Mu chitsanzo ichi, tikambirana lalikulu atatu ndi zitatu, chilinganizo amaonekera kotero (n - chiwerengero cha mizati):

Choncho, tili ndi lalikulu. Chinthu choyamba kuchita - kulowa nambala imodzi pakatikati pa mzere woyamba kuchokera pamwamba. manambala onse wotsatira ayenera kuyikidwa mu malamulo omwewo khola pa opendekera.

Koma nthawi yomweyo funso n'lakuti, kuthetsa lalikulu matsenga? Kalasi 3 chodziwikiratu kugwiritsa ntchito njira imeneyi, ndipo anthu ambiri adzakhala ndi vuto, momwe izo mwa njira iyi, ngati izi siziri selo? Kuti mukonze zinthu, muyenera kugwiritsa ntchito luso lanu la kuyerekezera ndi kutsiriza yemweyo matsenga lalikulu pamwamba ndi likukhalira kuti nambala 2 adzakhala mu selo m'munsi bwino. Choncho, mu lalikulu wathu ife kulowa awiri mu malo omwewo. Izi zikutanthauza kuti tiyenera kulowa manambala kuti pamodzi iwo anapereka mtengo wa 15.

manambala wotsatira woyenera chimodzimodzi. Kuti ndi 3 adzakhala pakati pa ndime yoyamba. Koma 4 sadzatha kulemba mfundo imeneyi, popeza malo ake ndi kale unit. Pankhaniyi, nambala 4 ili pansi 3, ndi kupitiriza. Zisanu - pakati lalikulu, 6 - mu chapamwamba lamanja ngodya, 7 - 6, 8 - lamanzere chapamwamba ndipo 9 - pakati pa mzere pansi.

Inu tsopano kudziwa mmene angathetsere lalikulu matsenga. Demidov anakonza kalasi 3, koma wolemba uyu anali zosavuta ntchito, koma podziwa njira kuti athe kuthetsa mavuto amenewo. Koma izi, ngati wosamvetseka angapo mizati. Ndipo chochita, ngati tili Mwachitsanzo, apakati 4 4? Imeneyi mu lemba.

Yachiwiri njira. Kuti lalikulu parity awiri

Square awiri parity amatchedwa wina ndi chiwerengero cha mizati akhoza anapambulwa ndi 2, komanso 4. Tsopano tikambirana lalikulu 4 4.

Choncho, kuthetsa lalikulu matsenga (kalasi 3, Demidov, Kozlov, woonda - mu buku la masamu), pamene chiwerengero cha mizati yake ndi wofanana 4? Ndi yosavuta. Mosavuta kuposa chitsanzo patsogolo.

Mu malo oyamba ife tikupeza zonse zamatsenga ntchito chilinganizo chomwecho chimene chinaikidwa mu nthawi yotsiriza. Muchisanzo chimenechi, chiwerengero ndi 34. Tsopano inu muyenera kumanga manambala ngati kuti Uwerenge umodzi, yopingasa ndi opendekera ali yemweyo.

Choyamba tiyenera kujambula zina mwa maselo kuchita ichi, mungathe pensulo kapena m'maganizo. Kujambula pa kumathandiza kupeza ngodya zabwino zonse, ndiye chapamwamba-lamanzere selo ndi ufulu chapamwamba, wamanzere ndi kutsikira bwino. Ngati lalikulu adzakhala 8 8, ndiye si koyenera kujambula bokosi lina mu ngodya, ndi zinayi, kuyeza 2 ndi 2.

Tsopano muyenera kujambula likulu a lalikulu, kotero kuti kumathandiza kupeza ngodya ya ngodya nkhawa kale shaded maselo. Muchisanzo chimenechi, ife apakati pa mzinda wa 2 ndi 2.

Kupeza kudzazidwa. Adzadzadza kuchokera kumanzere kupita kumanja ndondomeko imene maselo ili, monga kulowa mtengo adzakhala maselo shaded. Iwo likukhalira kuti chapamwamba kumanzere ngodya 1 analowa mu kumanja - 4. Kenako lembani chapakati 6, 7, ndi zina 10 ndi 11. kumanzere m'munsi ndi ufulu 13 - 16. Ife timakhulupirira ndondomeko chodzaza bwino.

Maselo atsala anadzazidwa mu njira imodzi, mu dongosolo atsikira. Zimenezo nchifukwa chakuti otsiriza wakhala alembedwa chithunzi 16, pamwamba pa sikweya kulemba 15. Komanso 14. Kenako 12, 9 ndi zina zotero, monga mmene tionela pacithunzi-thunzi.

Tsopano inu mukudziwa momwe chachiwiri kuthetsa lalikulu matsenga. Kalasi 3 amavomereza kuti m'bwalo la iwiri parity ndi zosavuta kwambiri kuthetsa kuposa ena. Chabwino, ife titembenukira kwa njira otsiriza.

Njira yachitatu. Kuti lalikulu ndi parity single

Square umodzi parity amatchedwa lalikulu chiwerengero cha mizati kuti angathe kugawidwa mmagawo awiri, koma osati zinayi. Pankhaniyi, m'bwalo la 6 6.

Kotero, ife kuwerengera nthawi zonse zamatsenga. Ndi wofanana 111.

Tsopano tiyenera lalikulu zowoneka ogaŵikana anayi lalikulu zosiyanasiyana 3 ndi 3. 3 ndi kukula kwa anayi yaing'ono lalikulu 3 lina lalikulu 6 6. kumanzere Upper akutchedwa A, m'munsi bwino - B, pamwamba pomwe - wamanzere ndi C - D.

Tsopano muyenera kuthetsa lililonse lalikulu yaing'ono, pogwiritsa ntchito njira pachiyambi kuti amaperekedwa m'nkhani ino. Iwo likukhalira kuti lalikulu A ndi manambala 1 mpaka 9, mu V wa - 10 18, C - by 19 27 D - kuchokera 28 mpaka 36.

Ngati mwaganiza mabwalo onse anayi, ntchito adzayamba pa A ndi D. Ziyenera kukhala mu lalikulu A zowoneka kapena ndi pensulo anawagawa maselo atatu, ndicho chapamwamba kumanzere, wamanzere, ndi pakati. Kunja kuti manambala allocated - ndi 8, 5 4. Mofananamo, m'pofunika kuzindikira ndi Square D (35, 33, 31). Onse amene amapitiriza kuchita ndi sinthanani manambala allocated a lalikulu D kuti A.

Tsopano inu mukudziwa momwe otsirizawa momwe mukhoza kuthetsa lalikulu matsenga. Kalasi 3 lalikulu limodzi parity sakonda kwambiri. Zimenezi n'zosadabwitsa, chifukwa onse anapereka kovuta kwambiri.

Pomaliza

Nditawerenga nkhani imeneyi, mwaphunzira kuthetsa lalikulu matsenga. Kalasi 3 (Moreau - wolemba la sukulu) amapereka ntchito zofanana ndi maselo ochepa wodzazidwa. Taganizirani chitsanzo chake sizimatanthauza, monga kudziwa njira zonse zitatu, inu mosavuta kuthetsa zolinga onse akupemphedwa.
