Indlela Ufunda indlela yokuxazulula izinkinga izibalo ngaphandle umzamo kakhulu?

Ngokuhamba wezibalo edingekayo ukuhlangabezana zonke izinhlobo zibalo nezinkinga, kodwa kubangele izinkinga eziningi. Lonke Iphuzu liwukuthi kudingeka usebenzele ukuba uhambe futhi ngokuzenzakalelayo kilelihlelo. Kanjani ukuze ufunde ukuze uxazulule izinkinga izibalo, ukuqonda kwabo, uyofunda kulesi sihloko.

Imisebenzi elula

Asiqale nge elula. Kuyadingeka ukuqonda essence yayo, ngakho-ke, kubalulekile ukuba aqeqeshe izibonelo esilula esikoleni sabaqalayo ukuthola impendulo efanele inkinga. Indlela Ufunda indlela yokuxazulula izinkinga zezibalo, sizobe ukuchaza kuwe kule ngxenye, izibonelo ezithile.

Isibonelo 1: Ivan futhi Dima babamba izinhlanzi ndawonye, kodwa Dima pecked kabi. Yini Ubamba abafana? Dima babamba izinhlanzi 18 lincane lonke catch, omunye guys izinhlanzi 14 ezincane kunenye.

Lesi sibonelo asuka Yiqiniso wezibalo telibanga lesine. Ukuze kuxazululwe le nkinga, kubalulekile ukuqonda essence yayo, umbuzo ngqo ukuthi ukuphela udinga ukuthola. Lesi sibonelo isixazululekile e ezimbili ezilula zinyathelo:

18-14 = 4 (inhlanzi) - wabanjwa Dima;

18 + 4 = 22 (inhlanzi) - wabanjwa guys.

Manje ungakwazi ukubhala ngokuphepha phansi impendulo. Siyakhumbula umbuzo oyinhloko. Uyini catch Imininingwane? Impendulo: izinhlanzi 22.

ISIBONELO 2:

Flying ukhozi nondlunkulu, kuyaziwa ukuthi undlunkulu lafika ngendiza amahora amabili nane amakhilomitha, futhi ukhozi ezintathu amahora landizela 210 amakhilomitha. Kukangaki ijubane ukhozi ngaphezulu.

Siphawula ukuthi kule Ngokwesibonelo, imibuzo emibili uqopha yalokho, ungakhohlwa ibonisa izimpendulo ezimbili.

Thina uqhubekele isinqumo. Lo msebenzi kudinga ukuba ngazi ifomula: S = V * T. Yena impela aziwayo kwabaningi.

isixazululo:

14/2 = 7 (km / h) - isivinini undlunkulu;

210/3 = 70 (km / h) - isivinini Eagle;

70/7 = 10 - kaningi Eagle Isivinini idlula undlunkulu Isivinini;

70-7 = 63 (km / h) - ukuze Isivinini ingasaphathwa undlunkulu isivinini Eagle.

Bhala impendulo: izikhathi 10 isivinini Eagle idlula undlunkulu isivinini; 63 km / h ngokushesha kunokuba undlunkulu ukhozi.

Izinga ezingcono

Indlela Ufunda indlela yokuxazulula izinkinga izibalo usebenzisa itafula? Kulula kabi! Njengomthetho, amatafula zisetshenziselwa lula nemibandela nokumisa. Ukuze uqonde le ndlela, udabule isibonelo.

Nasi lezincwadi ne emashalofini ezimbili, izincwadi ngolokuqala ngokuphindwe kathathu ngaphezu kweyesibili. Uma nge umlenze wokuqala kude izincwadi eziyisishiyagalombili, kanti eyesibili ukubeka 32, zizokwenziwa zibe ihlukaniseke ngokulinganayo. Phendula umbuzo: bangaki amabhuku babedabuka ku eshalofini ngamunye?

Kanjani ukuze ufunde ukuxazulula izwi izinkinga izibalo, thina manje konke ngokucacile show. Ukuze kube lula bezibona izimo ukwakheka itafula.

isimo

	1 eshalofini	2 eshalofini
kwaba	3	x
yaba	3-8	x + 32

Manje singenza ezothando:

8 3x = x + 32;

3, x = 32 + 8;

2 = 40;

x = 20 (izincwadi) - kwaba ngosuku lwesibili eshalofini;

20 * 3 = 60 (izincwadi) - kwaba eshalofini kuqala.

Impendulo: 60; 20.

Nasi isibonelo esihle yokuxazulula le nkinga iyabheda ekulungiseleleni ezothando usebenzisa etafuleni asizayo. It lula kakhulu umbono.

logic

kukhona imisebenzi eminingi ngokuhamba wezibalo. Kanjani ukuze ufunde ukuze uxazulule izinkinga logic mathematics, sizobheka kulesi sigaba. Ukuze uqale ukuthola isimo bamba, liqukethe izinto eziningana:

1. Sine phambi kwethu ishidi izinombolo kusuka 1 kuya 2009.
2. Sawela zonke izinombolo aphambene.
3. Kulaba esisele inani asusiwe ukuma ngesikhathi lingalingani izindawo.
4. Isenzo sokugcina kwenziwe kuze kube yilesi sikhathi, kuze inombolo eyodwa uhlala.

Umbuzo: bangaki kwesokunxele uncrossed?

Kanjani ukuze ufunde ngokushesha indlela yokuxazulula izinkinga zezibalo ku logic? Ukuze uqalise ekujaheni ukubhala zonke lezi zinombolo kanye abatelekile ngokulandelana, kholwa kimi, kuba umsebenzi eside kakhulu futhi beyiziphukuphuku. Umsebenzi walolu hlobo Kulula ukuxazulula, futhi izinyathelo ezimbalwa. Sinikeza ndawonye ukuba uzindle isinqumo.

Stroke izixazululo

Ake ucabange ngalokho izinombolo kuzohlala emva Isenzo sokuqala. Uma zonke lingalingani isikhishiwe, yilezi: 2, 4, 6, 8, ..., 2008. Kumele kuqashelwe ukuthi wonke ngeembuyabuyelelo ezimbili.

Uvuna enanini lingalingani ensimini. Yini thina sishiye? 4, 8, 12, ..., 2008 Siphawula ukuthi wonke ngeembuyabuyelelo amane (okungukuthi, ngaphandle lonke uhlukaniswa kane).

Ngokulandelayo, ukususa izinombolo enkundleni aphambene. Siye bagcina ne uchungechunge inombolo: 8, 16, 24, ..., 2008 Mhlawumbe usuke kakade ukuyichaza ukuthi wonke ngeembuyabuyelelo eziyisishiyagalombili.

Kulula ukuqagela mayelana nohlelo lwethu eziolandelayo. ngale ndaba ka ngeembuyabuyelelo 16, bese 32, bese 64, 128, 256.

Lapho sifika kulo ngeembuyabuyelelo 512, khona-ke nathi izinombolo ezintathu kuphela: 512, 1024, 1536 Isigaba esilandelayo reserve amaningi ka 1024, kuba kuhla lwethu ingenye 1024.

Njengoba ubona, inkinga isixazululekile aphansi, ngaphandle kokuzabalaza, kanye nenqwaba isikhathi esichithwa.

Olympic

Esikoleni kukhona into okuthiwa ama-Olympics. Ukuze uthole izingane abanamakhono akhethekile. Kanjani ukuze ufunde ukuze uxazulule izinkinga izibalo Olympic, nokuthi zingabantu, sibheke esilandelayo.

Kufanele uqale nge sezingeni leliphasi, sibe nzima nakakhulu-ke. amakhono Umsebenzi ukuxazulula izinkinga Olympic ukunikela izibonelo.

Olympics, Libanga 5. Isibonelo.

Epulazini lethu siphile ayisishiyagalolunye izingulube, bayadla izinsuku ezintathu futhi izikhwama ukudla amabili nesikhombisa. Umakhelwane wabuza umlimi ilivu yakhe ezinhlanu izingulube ezinhlanu izinsuku. Kungakanani udinga ukondla izingulube ezinhlanu izinsuku ezinhlanu?

Olympics, Libanga 6. Isibonelo.

Ukhozi olukhulu izimpukane amamitha amathathu ngomzuzwana, futhi eaglet imitha elilodwa ngesigamu sesibili. Bobabili baqala komunye vertex kwenye. Bangaki omdala ukhozi kuzodingeka silinde zengane, uma ibanga phakathi iziqongo 240 amamitha?

izixazululo

Esigabeni sokugcina, sabuka imisebenzi elula ezimbili Olympic walesigaba lesihlanu nelesithupha. Kanjani ukuze ufunde ukuze uxazulule izinkinga izibalo Olympic ezingeni, siphakamisa ukucabangela njengamanje.

Asiqale kusukela ebangeni lesihlanu. Yini esiyidingayo ukuze uqale? Thola ukuthi bangaki izikhwama kudliwa ayisishiyagalolunye izingulube ngosuku olulodwa, ngoba ukwenza ukubala elula: 27: 3 = 9. Sithole eziningi amasaka ayisishiyagalolunye izingulube ngosuku.

Manje ukubala malini udinga ukuba esinye isikhwana ingulube ngelanga: 9: 9 = 1. Khumbula lokho okwashiwo e isimo, umakhelwane kwesokunxele izingulube ezinhlanu izinsuku ezinhlanu, ngakho-ke sidinga 5 * 5 = 25 (okuphakelayo izikhwama). Impendulo: izikhwama 25.

Isixazululo for lesithupha:

240: 3 = 80 imizuzwana flying ukhozi oludala;

eaglet 1 yesibili izimpukane ezimbili amamitha, ngakho-ke: 80 * 2 = 160 amamitha impukane eaglet for 80 imizuzwana;

240-180 = 80 amamitha fly Eaglet, lapho ukhozi omdala awelele edwaleni;

80: 2 = 40 imizuzwana usadinga Eaglet ukufinyelela, ukhozi oludala.

Impendulo: amasekhondi angu-40.
