Can we solve this cryptarithm? It's pretty difficult. This is probably the hardest challenge for you. I times KINGJO equals JOKING So we've given you a hint here - that I equals to 4. Can you solve it?

Solve the alphametic part of the course challenge

OK! Let’s get down to the course challenge. Try and solve the following cryptarithm: I x KINGJO = JOKING The hint is: I=4

This isn’t an easy one, so spend some time on it. You can ask for hints in the discussion, but don’t give away the answer. That you’ll be able to see on the next step. Good Luck!
