My first thought when I looked at this was, "Yow, this is hard." I still think it's pretty hard, but I also think that it's a nice way to get people to think about math and to reframe math problems in an interesting way. The idea is that the diamond represents a function which, when defined, will yield a value of '666' when combined with the rest of the problem. So if you have, say "◇665" then the correct answer is "f(x) = x+1". See that I mean? You're thinking of math in terms of functions, not just numbers and variables. It's been made into an app, but you don't actually need the app. If I were a teacher, I'd offer one of these a day, starting with easy ones, and progressing through the year with more and more complex problems, rewarding the class (not an individual) if it's solved by the end of the day.
