Ndimasewera Masamu. Wapakati

Mu masamu, ambiri masamu a manambala (kapena pafupifupi) - Uwerenge manambala onse akonzedwa ichi, anagawa ndi nambala yawo. Awa ndi ambiri ndipo zowombetsa mkota mfundo kukula pafupifupi. Monga mukudziwa, kupeza phindu ambiri, m'pofunika n'cigwagwa onse deta muyenera muchigawane mwa chiwerengero cha mawu.

Kodi masamu zikutanthauza?

Tiyeni tione chitsanzo.

Chitsanzo 1. Popeza manambala 6, 7, 11. Tiyenera kupeza phindu pafupifupi.

Kusankha.

Kuyamba, kupeza Uwerenge manambala onse deta.

6 + 7 + 11 = 24

Tsopano kugawa kuchuluka chifukwa ndi chiwerengero cha mawu. Popeza tili ndi mawu atatu, motero, ife kugawanitsa ndi atatu.

24: 3 = 8

Choncho, phindu pafupifupi ya manambala 6, 7 ndi 11 - ndi 8. N'chifukwa 8? Chifukwa kuchuluka kwa 6, 7 ndi 11 mofanana eights atatu. Izi akuonekera bwino mu fanizoli.

Mtengo pafupifupi kungafanane kwa "kukhazikika" a manambala. Monga mukuonera, gulu la mapensulo akhala mlingo chomwecho.

Tiyeni tione chitsanzo china, kulimbitsa kudziwa kwawo.

2. Popeza manambala: 3, 7, 5, 13, 20, 23, 39, 23, 40, 23, 14, 12, 56, 23, 29. M'pofunika kupeza phindu pafupifupi.

Kusankha.

Ife tikupeza ndalama.

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

Gawani ndi nambala ya mawu (Pankhaniyi - 15).

330: 15 = 22

Choncho, zikutanthauza mtengo wa ya manambala ndi wofanana 22.

Tsopano tiyeni tione manambala negative. Kumbukirani momwe mwachidule iwo. Mwachitsanzo, muli manambala awiri 1 ndi -4. Kodi kupeza ndalama zawo.

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

Podziwa ichi, tiyeni tione chitsanzo china.

Mwachitsanzo 3. Pezani phindu zikutanthauza la manambala: 3, -7, 5, 13, -2.

Kusankha.

Pezani Uwerenge manambala.

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

Popeza mawu a 5, gawani kuchuluka chifukwa ndi 5.

12: 5 = 2,4

Choncho, masamu zikutanthauza mtengo wa 3, -7, 5, 13, -2 ndi 2.4.

Masiku ano, patsogolo sayansi ndi zambiri yabwino ntchito kupeza phindu avareji mapulogalamu. Microsoft Office kupambana - mmodzi wa iwo. Fufuzani pafupifupi phindu mu kupambana yachidule ndi yosavuta. Makamaka, pulogalamuyi ndi pa Microsoft Office mapulogalamu phukusi. Taganizirani malangizo mwachidule, momwe kupeza masamu zikutanthauza mtengo ndi pulogalamu imeneyi.

Pofuna kuwerengera phindu avareji mndandanda wa manambala, ntchito ntchito OKWANA. The malembedwe kwa nchito imeneyi:
= Avereji (argument1, argument2, ... argument255)
kumene argument1, argument2, ... argument255 - mwina ndi manambala kapena maumboni maselo (maselo anatanthauza ranges ndi magulu).

Kupanga izo momveka kwambiri, ife udzayesera kudziwa adapindulapo.

1. Lowetsani nambala 11, 12, 13, 14, 15, 16 C1 selo - C6.
2. Sankhani selo C7, mwa kuwonekera pa izo. Mderali tiyenera kusonyeza kufunika pafupifupi.
3. Dinani pa "Njira" tabu.
4. Sankhani More Nchito> kuti Statistical kutsegula mndandanda dontho-pansi.
5. Select OKWANA. Zitatha izi bokosi kukambirana liyenera kutsegula.
6. Sankhani ndi kukoka kuti selo C1-C6, kuti mwachindunji osiyanasiyana mu bokosi kukambirana.
7. Tsimikizani kanthu anu ndi kukanikiza "Chabwino".
8. Ngati inu anachita chirichonse molondola, selo C7, muyenera kuona yankho - 13.7. Mwa kuwonekera pa ntchito foni C7 (= Avereji (C1: C6)) adzakhala kuwonetsedwa chilinganizo bar.

yabwino kwa ntchito nchito imeneyi kuti kusunga kaundula, ma invoice wopelekedwa kapena pamene inu muyenera kupeza phindu avareji mndandanda wautali kwambiri za manambala. Choncho, kawirikawiri amagwiritsidwa ntchito maudindo ndi makampani akuluakulu. Zimenezi zimathandiza kusunga dongosolo la cikumbutso, ndi limachititsa msanga chilichonse (mwachitsanzo, ndalama pafupifupi pamwezi). Komanso mothandizidwa ndi kupambana, mungapeze phindu avareji kugwira ntchito.
