<prompt> Bheka isiqephu esingezansi bese uphendula umbuzo ngemuva kwalokho ngolimi olufanayo nesiqephu: Isiqephu: Izinhlelo eziningi zezinombolo, ezinjengezinombolo eziphelele kanye nezinengqondo zijabulela isakhiwo seqembu esinikezwe ngokwemvelo. Kwezinye izimo, njengakuma-rational, zombili imisebenzi yokuhlanganisa nokuphindaphinda idala izakhiwo zeqembu. Izinhlelo ezinjalo zezinombolo zingamanduleli wezakhiwo ezijwayelekile ze-algebraic ezaziwa njengamaroli nezinkambu. Eminye imiqondo ye-algebraic ebonakalayo efana namamojula, izikhala ze-vector kanye nama-algebra nayo yakha amaqembu. Umbuzo: Yiziphi izibonelo ezimbili zezakhiwo ze-algebraic jikelele?  <response>: izindandatho nezinkambu
