Kunakidza Mathematics. pakati nepakati

In masvomhu, kuti svomhu avhareji nhamba (kana paavhareji) - Verengai nhamba zvose izvi yakatarwa, yakakamurwa nokuwanda. Ndiwo kupfuura kwose kwose uye generalized yokuti avhareji saizi. Sezvaunoziva, kuwana paavhareji mutengo, zvakakodzera aunganidze ose mashoko raunoda mugovane nenhamba mazwi.

Chii svomhu kunoreva?

Ngatimboonai muenzaniso.

Muenzaniso 1. Vakapiwa kuwanda 6, 7, 11. Tinofanira kuwana kwavo avhareji ukoshi.

Decision.

Chokutanga, kuwana Verengai vose kuwanda mashoko.

6 + 7 + 11 = 24

Zvino unofanira kugovera kunoguma mari maererano nokuwanda mazwi. Sezvo tine mashoko matatu, ukuwo, isu kugovera matatu.

24: 3 = 8

Somugumisiro, avhareji kukosha nhamba 6, 7 uye 11 - ndiko 8. Nei 8? Nekuti uwandu 6, 7 uye 11 zvichava zvakafanana eights matatu. Izvi zvinoonekwa pachena mumufananidzo.

Avhareji anokosha fananei kuti "munoenzanisa" nhamba. Sezvaunogona kuona, boka nepenzura vava chete chechetere.

Funga mumwe muenzaniso, kusimbisa ruzivo rwavo.

Muenzaniso 2. Tichifunga kuwanda: 3, 7, 5, 13, 20, 23, 39, 23, 40, 23, 14, 12, 56, 23, 29. Zvakakodzera kuwana kwavo avhareji ukoshi.

Decision.

Tinoona Verengai.

3 + 7 + 5 + 13 + 20 + 23 + 39 + 23 + 40 + 23 + 14 + 12 + 56 + 23 + 29 = 330

Divide nenhamba mazwi (mu iyi - 15).

330: 15 = 22

Somugumisiro, Zvichakadaro kukosha yakatarwa nenhamba akaenzana 22.

Zvino funga akaipa nhamba. Yeuka kuti ipe nyaya navo. Somuenzaniso, mune nhamba mbiri dziri 1 uye -4. Uchawana mari yavo.

1 + (-4) = 1 - 4 = -3

Achiziva izvi, ngatikurukurei mumwe muenzaniso.

Muenzaniso 3. Find Zvichakadaro ukoshi nhamba: 3, -7, 5, 13, -2.

Decision.

Find Verengai nhamba.

3 + (-7) + 5 + 13 + (-2) = 12

Sezvo chibvumirano 5, zviparadzanise zvichiita mari ne 5.

12: 5 = 2,4

Somugumisiro, svomhu kunoreva kukosha 3, -7, 5, 13, -2 iri 2.4.

Mazuvano, kwezvinhu mberi zvikuru nyore kushandisa kuwana avhareji ukoshi ekombiyuta. Microsoft Office Excel - mumwe wavo. Search avhareji kukosha Excel nokukurumidza uye nyore. Kunyanya, chirongwa ichi chiri Microsoft Office yekombiyuta. , Funga mirayiridzo pfupi sei kuwana svomhu Zvichakadaro ukoshi pamwe chirongwa ichi.

Kuti kuverenga paavhareji ukoshi munhevedzano nhamba, shandisa AVHAREJI basa. The nemarongerwo nokuti basa iri:
= Avhareji (argument1, argument2, ... argument255)
apo argument1, argument2, ... argument255 - zviri kana nhamba kana sero nezvakanyorwa (nokuti masero raireva neeSultan uye arrays).

Kuti kuita zvakawanda pachena, isu ichaedza zivo yawana.

1. Enter nhamba 11, 12, 13, 14, 15, 16 muchitokisi C1 - C6.
2. Sarudza Sero C7, kuburikidza nekudzvanya pamusoro payo. In nzvimbo ino, isu tigokuzivisai avhareji kukosha.
3. Click on "Zvituko" Tab.
4. Sarudza More rutina> Statistical kuti uvhure donhwe-pasi pasi.
5. Select AVHAREJI. Pashure mubhokisi iri nhaurirano kunofanira kuzarura.
6. Sarudza uye zvuva nechitokisi C1-C6, kuti kutaridzwa siyana iri nhaurirano bhokisi.
7. Zadzisai chiito yako nokutsikirira "OK".
8. Kana iwe wakaita zvose zvakarurama, sero C7, unofanira kuona zvaanoitawo - 13.7. By nekudzvanya pamusoro sero basa C7 (= Average (C1: C6)) zvichakurukurwa akaratidza muna fomura kubhawa.

Very nyore kushandisa basa iri kuti rekodhi-kuchengetwa, invoices kana kana iwe chete vanofanira kuwana paavhareji ukoshi refu kwazvo akatevedzana nhamba. Saka, zvinoita rinowanzoshandiswa mumahofisi uye makambani makuru. Izvi zvinobvumira kuti kuchengetedza hurongwa zvinyorwa, uye zvinoita kuti ukurumidze kuwana chinhu (somuenzaniso, paavhareji mari pamwedzi). Uyewo tichibatsirwa Excel, unogona kuwana avhareji kukosha mashandiro.
