[[Hisabati|Kihisabati]], '''kisobadilika''' ni [[namba]] ambayo [[thamani]] yake haibadiliki.<ref>{{Cite book|url=https://somabiblia.com/wp-content/uploads/2019/12/kamusi-tuki-english-swahili-1.pdf|title=Kamusi ya Kiingereza-Kiswahili|publisher=TUKI}}</ref> Namba kama 1, 2, 3, n.k. ni visobadilika, lakini vinaweza kuchukua thamani zisizofahamika. Kwa mfano, fikiria [[mlinganyo]] wa [[husisho mstari]]:

<math>f(x)=ax+b</math>

Hapa, {{Mvar|x}} ni [[Kigeugeu (hisabati)|kigeugeu]], namba ambayo thamani yake siyo thabiti. Namba {{Mvar|a}} na {{Mvar|b}} ni visobadilika; thamani zake ndizo thabiti hata zisipofahamika. Kisobadilika chenye thamani isiyofahamika mara nyingi huitwa [[kizigeu]].
