We already talked about the way to fix it here, but they are marked as spoilers.

Try reading up on the max method and how it works with different data types.

hey, i have some problem with this test case too, .max just return 6 every time until you remove it or change, help please

Thanks both this makes sense

I am the author of the Ruby version and I think I don't get your question correctly: I checked and both sample tests cases and the actual submission cases correctly expect 542; what is the issue you are encountering, exactly?

Hey great kata, just wondering why .max returns 6 on the first test rather than 542 though (ruby), does anybody know?
