How can I prove this?
Hint: what might it be mod3 ?
Sorry, I dont get it...
What might it be mod3?
I see that mod9 - mod6 gives mod3
Division of 3 gives an odd number
mod9-mod6=mod3???? That's not right. What tiny-tim is suggesting is that if you know x=2 mod 6 then you can figure out what x is mod 3. Ditto for x=3 mod 9.
