Kuthetha ukuthini ukucinga emva?Ityala lengxaki yokutyhala inverse kwishishini leMengniu

Kuthetha ukuthini ukucinga emva?Imeko yengxaki eguqukayo kwishishini likaMengniu (elixabisa isigidi esinye) Ukuba ingundoqo yokucinga iguqulwe, ayigxininisi kwiinjongo ezinokufezekiswa phantsi kweemeko ezikhoyo.Umzekelo: ufumana imali engakanani ngonyaka?Kunoko, igxininisa kwiimeko kunye neendlela zokufikelela kwiinjongo: ezifana...

Eli nqaku lifuna ukwabelana ngengcinga yenguquko:

• Kuthetha ukuthini ukucinga ngenguquko?
• Indlela yokucinga yokuguqula isinceda njani senze imali?

iindaba ezintshaIshishini leentengiso linengxaki, njenge "Goldbach Conjecture".

Yintoni ingcamango yeGoldbach?

Ingqikelelo yeGoldbach yenye yeengxaki ezindala ezingasonjululwanga kwithiyori yamanani.

Le ngcamango yavela okokuqala kwimbalelwano yowe-1742 phakathi kwePrussian Christian Goldbach kunye nesazi sezibalo saseSwitzerland uLeonhard Euler.

Kwimathematika yanamhlanje, uqikelelo lukaGoldbach lunokubonakaliswa ngolu hlobo:

• "Naliphi na inani elikhulu kuno-2 linokumelwa njengenani lamanani amabini aphambili."
• Le ngcamango iyahambelana namanani aseYurophu ngelo xeshaisayensiKukho uqhagamshelo kwingxaki edityanisiweyo yokwenziwa kwezinto ezixoxwe ngababhali.

EzorhweboOosomashishini (oosomashishini) banenkxalabo malunga notyalo-mali lwemali, ngaba inokuvelisa imbuyekezo ehambelanayo?

Kodwa nangona kunjalo, oosomashishini abaninzi bafuna ukwenzauKhuthazo lweWebhu, tyala i-1 USD ngokutshintshiselana nge-3 USD, i-5 USD okanye ngaphezulu.

Ndiyathemba ukuba intengiso esasazeka kwisibhakabhaka yonke iya kuba yinjongo echanekileyo.Intengiso ye-Wechatukukhangisa, ngaloo ndlela ukufezekisa injongo "yonke imbumbulu itshabalalisa intshaba".

Kuphela emva koko wenzeUkunyuswa kweakhawunti yoluntuIindleko zentengiso "kukubeka imali yakho apho umlomo wakho ukhoyo".

EzininziWechatKwaye abantu abatsha beendaba bafuna ukwazi: yintoni inkunkuma "yesiqingatha sentengiso"?

Enyanisweni, lo mbuzo uhlolisiswe malunga nekhulu leminyaka, kwaye akukho mntu ufumene impendulo, kodwa umntu omnye ufumene ifomula yokuguqula ukufumana impendulo esondeleyo kule mpendulo.

Impendulo yile:

1 = 3 Ifomula yobutyebi

Ukuba ufunde incwadi ethi, "12 Months of a Millionaire," umbhali waloo ncwadi, uVincent, yincwadi yakhe kuphela.

• UVincent wayengumfundi kaJaya Braham.
• Umvuzo wakhe wonyaka ngaphambi kweminyaka eyi-30 idlula ingeniso edibeneyo yabaphathi abaninzi abaziintloko.
• Ukuthembela nje kwipeni, isiqwenga sephepha kunye nebhotile yeyeza kunokunceda uVincent oneminyaka engama-28 ubudala afumane i-1 yezigidi zeedola kwiminyaka emibini.

Enyanisweni, indlela kaVincent ilula kwaye iyasebenza.

Logama nje ufunda ukucinga, ungayisebenzisa kwangoko kwaye ube namandla njengeVincentuphawu！

Ityala lokwenza imali ngokucinga ngokuguqula

Ikwenza njani oku uVincent?

Ingcamango engundoqo ngamagama amabini - ukuguqulwa.

• Le yifomula yobutyebi awayifumana ngokuvavanywa—— 1 = 3

Uvavanya njani uVincent?

1. Waqala wathenga izintlu ezingama-9000 3000 zeemveliso ezifanayo awayezithengile, waza wahlulahlula ngokwamaqela amathathu anezinto ezingama-XNUMX XNUMX ngalinye.
2. Bala ixabiso leleta nganye yi-$0.6, i-3000 yindleko ye-1800 yeedola.
3. Kufuneka kubekho imiyalelo engama-30 yokwaphula.

Emva koko wabhala iintengiso ezintathu ezahlukeneyoukukhuphelaIileta, iikopi ezingama-3000 zakhutshwa:

• Ibhetshi yokuqala yee-odolo ezili-10, ulahlekelwe yimali
• Ibhetshi yesibini yee-odolo ze-15, ilahlekelwe yimali
• Ibhetshi yesithathu yee-odolo ezingama-30, caba

Emva koko, ibhetshi yesithathu yokubhala ikopi yaphuculwa ngakumbi kwaye yathunyelwa kwinqanaba elikhulu, kunye nereyithi yokuphendula eyi-2%.

Ukuthengwa okuphindaphindiweyo (ixabiso lobomi) kubalwe kwaye kwafumanisa ukuba umthengi ngamnye uthenge umyinge weebhotile ze-4.4 kwixesha leenyanga ezintandathu.

Emva kokutsala iindleko ngale ndlela, umxhasi ngamnye umhlawula i-180 yeedola kangangeenyanga ezintandathu.

Emva koko: iileta ze-1000 20 x 180 = 3600 iidola zase-US - iindleko yi-600 yeedola zase-US, ngoko ke iileta ze-1000 zinokufumana i-3000 yeedola zase-US.

Ngamanye amazwi, isiphumo soguqulo:Uya kufumana i-3 yeedola ngeleta nganye oyithumelayo.

• Le yifomula yobutyebi eveliswa yinguquko: 1 = 3 Ifomula yenzuzo.

Le fomyula ayinamathematika, kwaye kuphela abo baye benza ukuguqulwa bayazi imfihlelo.

Nje ukuba isiphelo sokuguqulwa senziwe, kuya kuba lula ukulandela, kwaye emva kokuphindaphinda okuninzi, ubutyebi buya kunyuka.

Shwankathela undoqo wokucinga ngenguquko

• Undoqo "wokuguqula ukucinga" kukubala"Umlinganiselo wemveliso(Umlinganiselo wegalelo)"
• Igalelo-imveliso ratio, eyaziwa ngokuba imbuyekezo kutyalo-mali, IsiNgesi isishunqulelo ROI
• Yimali oyenzayo ngokwenza into, yahlulwe yimali oyifakayo.
• Okukhona uphezulu umlinganiselo wegalelo-mveliso, kokukhona usenza imali eninzi.

Umzekelo, ubutyebi bendlela yokucinga (umlinganiselo wemveliso):

• Umlinganiselo wegalelo-imveliso = ixabiso langoku lengeniso yeprojekthi yotyalo-mali / utyalo-mali lweprojekthi × 100%
• 600 / 200 x 100% = 3

Ukudala ubutyebi yinkqubo ukusuka kwi-0 ukuya kwi-100:

• Ukusuka ku-0 ukuya ku-1 yeyona nto inzima.
• Nje ukuba uguqule ifomula yakho yobutyebi ukuya ku-1 = 3
• Emva koko kulula kakhulu ukusuka kwi-1 ukuya kwi-100.

Ewe, nantsi ke namhlanje.
