Inombolo yesisekelo 12: Umlando omfushane
Izinombolo eziyisisekelo 12, ezaziwa nangokuthi izinombolo ze-duodecimal, isuka emasikweni asendulo ahlukahlukene. Lolu hlelo kukholakala ukuthi lwasuka ekusetshenzisweni kwequnuckles (ngaphandle kwesithupha) ukubala, linikeza isamba samayunithi ayi-12 esandleni esisodwa. Kuwo wonke umlando, amasiko ahlukahlukene aye amukela lesi simiso ngamazinga ahlukahlukene. Phakathi kwabaziwa kakhulu kunabaseBabiloni, ababesebenzisa isimiso socansi esisekelweni sama-60, kodwa bahlukanisa izinombolo zabo ngamaqembu amancane angu-12; kanye nabaseGibhithe lasendulo, ababesebenzisa uhlelo lwe-duodecimal ekulinganiseni isikhathi.
Uhlelo lwe-duodecimal: izinombolo namagama
Ohlelweni lwezinombolo ezingu-12, izimpawu eziyi-12 ezihlukene zisetshenziselwa ukumela izinombolo: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A (10), kanye no-B (11). Ngezansi kunohlu lwezinombolo eziyisisekelo eziyi-12 nezilingana nazo ngesi-Spanish, okuhlanganisa ifonetiki kubakaki:
- 0 – uziro (/'θe.ro/)
- 1 – eyodwa (/'u.no/)
- 2 - ababili (/ ababili/)
- 3 - ezintathu (/'ntathu/)
- 4 – ezine (/'kwat.ro/)
- 5 – ezinhlanu (/'θin.ko/)
- 6 - eziyisithupha (/sejs/)
- 7 – eziyisikhombisa (/'sje.te/)
- 8 – XNUMX (/'o.tʃo/)
- 9 – nine (/'nwe.βe/)
- A – ishumi (/'djeθ/)
- B – ishumi nanye (/'on.θe/)
Ukusetshenziswa okungokoqobo kwezinombolo ze-duodecimal
Uhlelo lwe-duodecimal lunezinzuzo ezithile, ikakhulukazi uma kuziwa ekusebenzeni ukubalwa kwe-arithmetic futhi kube lula ukuhlukana. Njengoba i-12 iyinombolo ehlanganisa kakhulu, inezahlukanisi eziningi kunanoma iyiphi inombolo encane kunayo (1, 2, 3, 4, 6, kanye no-12). Lokhu kwenza izingxenyana zibe lula.
Isibonelo sokusetshenziswa okungokoqobo kwesistimu ye-duodecimal singatholakala ku- ukulinganisa isikhathi. Njengoba sazi, usuku luhlukaniswe lwaba amahora angu-24, ihora ngalinye libe imizuzu engu-60, futhi umzuzu ngamunye ube imizuzwana engu-60. Lezi zigaba ziphathwa kalula ohlelweni lwe-duodecimal kunedesimali evamile.
Isisekelo se-12 kwezemfundo nocwaningo
Nakuba isistimu yedesimali ibusa kumasiko amaningi esimanje, intshisekelo ku-base 12 njengolunye uhlelo lwezinombolo iyaqhubeka. Abanye othisha nothisha, kanye nabacwaningi bezibalo nomlando, bayayibona ikhono lesimiso esinjalo futhi bakhuthaze ukufundisa kwaso njengento ehambisana nezibalo ezivamile. Lokhu kungasiza abafundi ukuthi bathuthukise ukuqonda okujulile nokune-nuanced okwengeziwe kwenombolo nokusebenza, kanye nokwazisa ukubaluleka kokuhlukahluka kumathuluzi ezibalo.
Izinombolo ze-Duodecimal kuzincwadi namasiko e-pop
Kuyathakazelisa ukuthi uhlelo lwezinombolo eziyisisekelo ezingu-12 nalo lenze uphawu lwalo ezincwadini nasesikweni le-pop. Ababhali bezinganekwane zesayensi namaphupho, okuhlanganisa namagama omndeni afana no-JRR Tolkien kanye no-Ursula K. Le Guin, basebenzise uhlelo emisebenzini yabo yezinganekwane ukuze bakhe enye imihlaba nezilimi ezicebile.
Kafushane, uhlelo lwezinombolo eziyisisekelo 12 lunikeza umbono ohlukile futhi ovame ukusebenza kakhudlwana ngezibalo nokuthi singawusebenzisa kanjani ukuveza imibono nokuxazulula izinkinga. Ngokubheka le ndlela ehlukile, asigcini nje ngokwandisa ukuqonda kwethu izibalo kodwa amandla ezinhlelo zezinombolo ngokuvamile.
