So I am supposed to find the b-complement for 193 given that b = 5 and the number of digits allowed is n = 6.

Now I think I am a bit confused regarding the b-complement in general.

Is it that whenever b is odd, just like in the case we have here, you are supposed to subtract 1 from the base and calculate the complement with the result?

If that's the case, you would calculate the 4-complement of 193, right? But do I then also subtract the then found out number from 444444 or still 555555?
