okubala
Ukucindezela inkinobho
izikhathi ezingaphezu kweyodwa kubonisa
izikrini zokusetha ezengeziwe.
Izilungiselelo ezidwetsheliwe ( ___ ) zizenzakalela kusukela ekuqaleni.
Deg Rad Gra
Icacisa amazinga, ama-radians noma ama-grads njengenombolo
yobungako bechopho yokufaka inani nokubonisa imiphumela yesibalo.
(90°= π /2 yama-radians = 100 wama-grads)
Fix Sci Norm
Icacisa inani lezinombolo ezihamba ngazodwa ezivezwa kumphumela
wesibalo.
Fix: Inani olichazayo (kusuka ku-0 kuya ku-9) lilawula inani lezindawo
zedesimali emiphumeleni yesibalo. Imiphumela yesibalo yenziwe
inombolo egcwele ngokuyiswa kwinombolo egcwele eseduze ngaphambi
kokuba ivezwe.
Isibonelo: 100 ÷ 7 = 14.286 (Fix 3)
14.29 (Fix 2)
Sci: Inani olichazayo (kusukela ku-1 kuya ku-10) lilawula inani
lezinombolo ezihamba ngazodwa ezibalulekile ngemiphumela yesibalo
eveziwe. Imiphumela yesibalo yenziwe inombolo egcwele ngokuyiswa
kwinombolo egcwele eseduze ngaphambi kokuba ivezwe.

Norm: Ukukhetha esinye sezilungiselelo ezimbili ezitholakalayo (Norm 1,
Norm 2) sinquma ububanzi lapho imiphumela ezoboniswa
ekuziphindaphindeni kwenombolo. Ngaphandle kwebanga elicacisiwe,
imiphumela iboniswa ngokusebenzisa ifomethi engekho yokuveza.
