8/9 Can't find my mistake


Hi there!
here's my code:

I've "true" on the screen but also I've a message as follows:
Oops, try again. Did you define your by_three? method?

What I did wrong?


Found it
Should be by_three? not by_tree?


You dont actually need the

if param

you just need
return number%3 ==0... bc if its true it returns true if not it returns false.
