Mafomura Ekuwanda Nokukurumidza
Kuwanda ndeimwe yemabasa makuru mumasvomhu, akakosha pakushandiswa kwakasiyana-siyana munzvimbo dzakasiyana-siyana, kubva pakuverenga kusvika kumainjiniya epamusoro. Mumazana emakore, nyanzvi dzemasvomhu nevadzidzisi vakagadzira mafomula akawanda ekuwanda nekukurumidza uye mazano ekuita kuti basa iri rive nyore, zvichiita kuti rive nyore uye risingatore nguva yakawanda. Chinyorwa chino chinoongorora dzimwe dzenzira idzi dzehunyanzvi dzinovimbisa kuita kuti kuwanda kuve nyore uye kukurumidze, zvisinei nenhamba dziripo.
Basic Kunzwisisa
Usati watanga kushandisa nzira dzekuwedzera nhamba nekukurumidza, zvakakosha kuti uve neruzivo rwekutanga rwekuwedzera nhamba. Chaizvoizvo, kuwanda inzira yekuwedzera nhamba (multiplicant) pairi kakati wandei (multiplicant).
Kuwanda ne10, 100, 1000, nezvimwewo.
Nzira iri nyore asi inobatsira zvikuru inosanganisira kuwanza nenhamba dzakadai se10, 100, 1000, nezvimwewo. Paunowanza nhamba nenhamba idzi, unongowedzera zero kumagumo kwenhamba.
- Muenzaniso:
\[7 \kawa 100 = 700\]
Kuwedzera zero mbiri pa7 kunopa 700.
- Muenzaniso:
\[53 \kawa 10 = 530\]
Kuwedzera zero imwe chete pa53 kunopa 530.
Kupeta kaviri uye Kupatsanura nehafu
Imwe nzira inoshanda inosanganisira kupeta nhamba imwe kaviri woipatsanura nehafu. Nzira iyi inoshanda zvikuru kana imwe yenhamba dzakaenzana asi inogona kuwedzerwa kune dzimwe nyaya zvakare.
- Muenzaniso:
\[16 \kawa 25\]
Kaviri kaviri 16 kuti uwane 32 uye kamura 25 nehafu kuti uwane 12.5. Zvino verenga:
\[32 \kawa 12.5 = 400.\]
Zviri nyore kubata nepfungwa nekuti kutarisa pazvikamu, kunyanya masimba e2, kunoita kuti maitiro acho ave nyore.
Nzvimbo Yekugovera
Hunhu hwekugovera chimwe chishandiso chinobatsira pakuwanda nekukurumidza. Iyi nzira inosanganisira kupatsanura nhamba imwe chete kana dzese kuita zvidimbu zviri nyore uye kudziwedzera zvakasiyana usati wawedzera mhedzisiro.
- Muenzaniso:
\[23 \kawa 7\]
Putsa 23 se \((20 + 3)\) wobva wawedzera chikamu chimwe nechimwe ne7:
\[20 \kawa 7 = 140\]
\[3 \kawa 7 = 21\]
Pakupedzisira, wedzera mhinduro mbiri:
\[140 + 21 = 161.]
Nzira Yechikwere
Nzira iyi inoshanda zvakanyanya pakuwandanisa nhamba dziri pedyo. Unotanga wawana pakati penhamba mbiri, wobva waisa nhamba iyi panhamba wogadzirisa musiyano mudiki.
- Muenzaniso:
\[19 \kawa 21\]
Nhamba dzese dziri pedyo ne20, pakati padzo.
Sikweya pakati nepakati:
\[20 \kawa 20 = 400\]
Sezvo 19 iri pasi pe1 pane 20 uye 21 iri pamusoro pe1 pane 20:
\[(20-1)(20+1) = 400 – 1 = 399.\]
Kushandisa Nhamba Dzekuwedzera
Nzira yekushandisa nhamba dzinoenderana inosanganisira kusarudza nhamba iri nyore iri pedyo neimwe yenhamba dziri kupetwa uye kushandisa kubvisa kugadzirisa chigadzirwa.
- Muenzaniso:
\[98 \kawa 97\]
Nhamba dzese dziri mbiri dziri pedyo ne100.
Zviparadzanise se \((100 – 2) \times (100 – 3)\):
\[100^2 – (2 \kawa 100 + 3 \kawa 100 – 2 \kawa 3)\]
\[10000 – (200 + 300 – 6) = 10000 – 494 = 9506.]
Nzira yeLattice
Nzira ye lattice inomiririra kuwanda zvinoonekwa zvinogona kurerutsa maitiro acho, kunyanya kune nhamba huru. Kunyangwe ingave isiri iyo nzira inokurumidza, inoita kuti zvive nechokwadi chekuti zvinhu zvakarurama.
- Muenzaniso:
Wedzera 23 ne41 uchishandisa grid re lattice:
1. Dhirowa gridhi re 2×2.
2. Kamura 23 kuita 2, 3 uye 41 kuita 4, 1.
3. Zadza grid:
4. Dzokorora diagonals:
- Dinagonal iri kuruboshwe ine 8.
– Madhayagiramu epakati anopa \(10 + 12 + 1 = 23\), saka nyora 3, famba ne2.
- Dhinari yekurudyi ndeye 3 pamwe ne2 inotakurwa, zvichipa 5.
Saka, \(23 \kawanzika 41 = 943\).
Nzira yeVedic yekuwedzera
Masvomhu eVedic akatanga kubva kuIndia yekare, anopa nzira dzakasiyana-siyana dzekuverenga nekukurumidza, kusanganisira kuwanda.
- Muenzaniso:
Kushandisa nzira yeVertically neCrosswise kuwanza 32 ne21:
1. Wedzera nzvimbo yemayuniti:
\[2 \kawa 1 = 2\] (nyora 2)
2. Wedzera mutsetse wepakati wobva wawedzera mhinduro:
\[(3 \kawa 1) + (2 \kawa 2) = 3 + 4 = 7\] (nyora 7)
3. Wedzera nzvimbo yegumi:
\[3 \kawa 2 = 6\] (nyora 6)
Saka, \(32 \kawa 21 = 672.\)
Kuwanda kweVarimi veRussia
Nzira iyi yekare inosanganisira kupeta kaviri nepakati. Nhamba imwe inopetwa nepakati, kubvisa zvikamu, uye imwe inopetwa kaviri. Mashoko apo nhamba ine hafu isingawanzoonekwi anopfupikiswa.
- Muenzaniso:
Kanda 18 ne25:
1. Nyora 18 ne25 padivi peimwe neimwe.
2. Kamura kaviri nepakati zvichiteerana:
– 9 (zvisinganzwisisike, chengeta 25)
- 4 ne50
- 2 ne100
– 1 (zvisinganzwisisike, chengeta 200)
Zvose zviri muchirevo ichi: \(25 + 200 = 225 + 50 = 450\).
Saka, \(18 \kawanza 25 = 450\).
mhedziso
Runako rwemasvomhu rwuri mukusiyana-siyana kwayo uye nzira dzakawanda dzekugadzirisa dambudziko. Maitiro ekuwanda nekukurumidza mienzaniso yakakwana yehunhu uhwu, ichishandura iro rinogona kunge riri basa rakaoma kuita maitiro anogoneka, kunyange anonakidza. Ungave uri mudzidzi ari kutsvaga nzira dzinokurumidza dzekubata masvomhu, nyanzvi inoda kuverenga zvinobudirira, kana kungoda masvomhu, kugona aya maitiro ekuwanda nekukurumidza pasina mubvunzo kuchawedzera kugona kwako kuverenga. Nekudzidzira nguva dzose, nzira idzi dzichava dzechipiri, zvichiita kuti kuwanda nekukurumidza uye kwakarurama kuve hunyanzvi hunofadza.
