 In contrast, let us imagine we do not know the value of `n`:
 
 ```scala
-power(2, unkownNumber)
+power(2, unknownNumber)
 ```
 Driven by the inline annotation on the parameter, the compiler will try to unroll the recursion.
 But without any success, since the parameter is not statically known.

 We will come back to this example later and see how we can get more control on how code is generated.
