Hello, Steemians!
Let me introduce to you my new mathematical contest. It was inspired by IQ tests and @cryptotem nice dice challenges!

The rules:

• Upvote and resteem this post
• Make a comment with your answer, where you explain it
• First right answer wins
• Answer not later than 6 September 23:59 UTC

The task:

Now you need to find a dependency between numbers and figures and then answer what number should be instead of "?".

Thank you for your attention!
