Chifukwa simungathe kugawaniza ndi ziro? phunziro

Zero pawokha ndi chidwi kwambiri. Chokha wachabechabe, pakalibe mfundo ndi pafupi fanizo lina zikuchulukirachulukira kufunika kwake mu nthawi 10. Pali mphamvu ziro nthawi zonse kupereka 1. chizindikiro akadali ntchito Maya chitukuko, ndipo iwo akadali anayimira mfundo "chiyambi chochititsa." Ngakhale mu kalendala ya anthu Maya anayamba ndi ziro-day. Ndipo chithunzi ichi amagwirizana ndi zoletsedwa kwambiri.

Kuyambira zaka sukulu oyambirira, ife bwino anaphunzira ulamuliro "simungathe kugawaniza ndi ziro." Koma ngati mwana anthu ambiri mu chikhulupiriro ndi wamkulu mawu sapezekapezeka chikaiko, mu nthawi zina mukadali kumvetsetsa zomwe zimayambitsa kumvetsa chimene malamulo inakhazikitsidwa.

Chifukwa simungathe kugawaniza ndi ziro? Pa funso ili ine ndikufuna kumvetsetsa lomveka. Mu mphunzitsi kalasi sakanakhoza kuchita izo, chifukwa mu masamu malamulo anafotokoza mothandizidwa ndi maikwezhoni, ndi pa usinkhu umenewo, ndipo ife tinalibe lingaliro chomwe chiri. Ndipo tsopano yafika nthawi kumvetsa ndi kupeza bwino lomveka chifukwa chimene inu simungathe kugawaniza ndi ziro.

Mfundo yakuti mu masamu, ziwiri zokha ntchito zinayi (+, -, ×, /) ndi anazindikira palokha: chulutsa ndi Kuwonjezera. Ena a opaleshoni imatengedwa kuti anachokera. Taganizirani chitsanzo yosavuta kumva.

Ndiuzeni ine, kuchuluka kwa momwe inu kupeza pamene inu kuchotsera 18 20? Mwachibadwa, mu mutu wathu yomweyo kuyankha kumeneko: zidzakhala 2. Ndipo tabwera choncho? Kwa ena funso zingaoneke zachilendo - pambuyo onse, chirichonse chiri bwino, zomwe zimachitika 2, wina kufotokoza kuti pakati pa masenti 20 ndi 18 zichotsedwe iye ali makobidi awiri. Nawatsimikizira onse mayankho awa si chipeneko Komabe, vutoli akhale osiyana maganizo a masamu. Kachiwiri, kuti waukulu ntchito masamu ndi kuchulukitsa ndi Kuwonjezera, ndi zina Pankhaniyi yankho lake lili pothetsa aone kuti pali zotsatirazi: × + 18 = 20. Zimenezo ndizoonekeratu kuti × = 20 - 18, × = 2. Zingaoneke, chifukwa onse tsatanetsatane kujambula? Ndipotu, chophweka kupulayimale. Komabe, popanda izi molimba chifukwa chake inu simungathe kugawaniza ndi ziro.

Tsopano tiyeni tiwone zomwe zimachitika ngati tikufuna 18 kugawanitsa ndi ziro. Kachiwiri kukhazikitsa aone kuti pali 18: × = 0. Popeza ntchito ya kugawikana lachokera ku chulutsa njira kuti asinthe aone kuti pali wathu timapeza × * 0 = 18. Uku n'kumene ndinayamba ndipo deadlock. Pali Xs mu malo pamene kuchulukitsa ndi ziro amapereka 0 ndi kutenga 18, ife analephera. Tsopano zimaonekeratu kwambiri chifukwa inu simungathe kugawaniza ndi ziro. Zero yokha akhoza kugawidwa mu chiwerengero mukufuna, koma m'malo mwake - kalanga, zosatheka.

Ndipo zomwe zimachitika ngati ziro anagawa yekha? Izi akhoza kulembedwa mu mawonekedwe: 0 0 = ×, kapena × * 0 = 0. aone kuti pali uyu ali wopandamalire chiwerengero njira. Choncho, chifukwa ali osawerengeka. Choncho, ntchito ya kugawikana ndi ziro , ndipo mu nkhani iyi, nayenso, chiribe tanthauzo.

Division mwa 0 pa muzu wa nthabwala ambiri kungoganiza masamu, amene ngati n'koyenera akhoza kudabwa munthu wosadziwa. Mwachitsanzo, taganizirani aone kuti pali: × 4 * - 20 * × = 7 - 35. anamasulira m'mabokosi 4 kumanzere ndi kumanja 7. kupeza 4 * (× - 5) = 7 * (× - 5). Tsopano kuchulukitsa kumanzere ndipo lamanja la aone kuti pali ndi nusu 1 / (× - 5). The aone kuti pali amatenga mawonekedwe: 4 * (× - 5) / (× - 5) = 7 * (× - 5) / (× - 5). Kuchepetsa kachigawo ndi (× - 5), ndipo tidzabwera kuti 4 = 7. tikhoza kunena kuti 2 * 2 = 7! Kumene, ndale apa ndiye kuti muzu wa aone kuti pali la ndiyofanana 5 ndipo kunali kosatheka kuchepetsa nusu, popeza zinachititsa magawano mwa ziro. Choncho, pamene kuchepetsa tuzigawo twa ayenera nthawi zonse onetsetsani kuti ziro si anali kukhala chimene chachititsa kuti, mwinamwake ndipo zotsatira zake zidzakhala sizimadziwika ndithu.
