Manambala zomveka ndi ntchito pa iwo

Lingaliro la chiwerengero amatanthauza abstraction uliri chinthu ku mfundo kachulukidwe ka view. Koma pali kufunika kuthamanga zinthu, kotero panali mayina n'zosangalatsa kumva mu wosazindikira anthu anthu. Kenako anakhala maziko a masamu ndi sayansi.

Kuti mupewe mfundo masamu, m'pofunika choyamba, talingalirani zomwe mtundu wa manambala ali. mitundu yambiri yaikulu ya manambala. Ali:

1. Natural - amene ife mu kuwerenga zinthu (Nkhani zawo zachilengedwe). Ambiri a iwo kuimira ndi Latin kalata N.

2. Zonse (zawo ndiwo amaimira kalata Z). Zikuphatikizapo zachilengedwe, mosiyana ndi iwo integers zoipa ndi ziro.

3. zomveka manambala (kalata Q). Iwo ndiwo amene akhoza ankayimiridwa ngati kachigawo, ndi numerator amene ali ofanana ndi inteja, ndipo ndi chimene chachititsa - zachilengedwe. Onse integers ndi manambala zachilengedwe ndi zomveka.

4. zenizeni (awo amaimira kalata R). Zikuphatikizapo manambala zomveka ndi zopanda nzeru. Otchedwa manambala zopanda nzeru ndi zomveka anachokera ku ntchito zosiyanasiyana (ndi mawerengedwe a logarithm muzu Tingafinye), eni okha zomveka.

Choncho, aliyense kukukhala awa ndi kagawo wa zotsatirazi. Chitsanzo cha nkhani yolembedwa ichi ndi chithunzi mu mawonekedwe T N.. Euler mabwalo. Chithunzi ndi kuchuluka kwa ovals concentric, omwe ili mkati zina. Wamkati, chowulungika wamng'ono kukula (dera) ndi ya nambala achilengedwe. Kwathunthu chimakwirira ndi zikuphatikizapo malo amene amaimira ya integers, amene nawonso, kwagona pa ulamuliro wa manambala zomveka. Kunja, wamkulu chowulungika chikukhudza ena onse, zimatanthauza khamu la manambala enieni.

M'nkhani ino tikulingalira ya manambala zomveka, katundu wawo ndi makhalidwe. Monga tanenera kale, iwo monga manambala zonse zosatha (zabwino komanso zoipa ndi ziro). manambala zomveka kuphatikiza mndandanda wopandamalire ndi katundu zotsatirazi:

- amaika izi analamula kuti, kutenga awiri aliwonse a manambala zino tikhoza nthawizonse amandiuza ndani wa iwo ali wamkulu;

- kutenga awiri aliwonse a manambala awa, ife nthawi zonse pakati pa iwo chimodzi, ndipo, chotero, chiwerengero cha anthu - manambala zomveka ndi mndandanda wopandamalire;

- zonse zinayi ntchito masamu pa manambala amenewa chifukwa cha iwo nthawizonse nambala inayake (ndi zomveka); kupatulapo magawano mwa 0 (ziro) - sikutheka;

- manambala aliyense zomveka akhoza ankayimiridwa ngati tuzigawo twa decimal. tuzigawo twa awa ikhoza kukhala amalire kapena wopandamalire nthawi.

Kuyerekeza manambala awiri zokhudza ya zomveka, tiyenera kukumbukira:

- chiwerengero zabwino kuposa ziro;

- chiwerengero zoipa nthawi zonse pasanathe ziro;

- pamene kuyerekeza awiri zoipa zomveka ochuluka ndiye amene mtheradi kufunika (modulus) zochepa.

Kodi kuchita zochita ndi manambala zomveka?

Kuti pindani manambala awiri ndi chizindikiro chomwecho, m'pofunika anagona makhalidwe awo mtheradi ndi kuika patsogolo Uwerenge chizindikiro chilichonse. Kuwonjezera manambala ndi zizindikiro zosiyana n'zofunika kwambiri kuchotsera zochepa ndi kuika chizindikiro yawo mtengo mtheradi ambiri.

Pakuti Kuchotsera nambala zomveka kwa chiwerengero china yokwanira woyamba kuwonjezera zosiyana chachiwiri. Pakuti kuchulukitsa chiwerengero awiri muyenera kuchulukitsa kufunika kwa mfundo zawo mtheradi. Ndipo zotsatira zake zidzakhala zabwino ngati zinthu ndi wa chizindikiro chomwecho, ndi zoipa ngati osiyana.

Kudulidwa wapangidwa chimodzimodzi, ndiye mfundo mtheradi ali mseri, ndipo chifukwa aikidwa kutsogolo kwa chizindikiro "+" zinachitikira mwangozi zizindikiro za lopeza ndi divisor, ndipo chizindikiro "-" ngati mismatch a.

KUSIYANA KWA manambala zomveka amaoneka ngati mankhwala zinthu zingapo ofanana ndi mnzake.
