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 "â—‡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. Here's the home page for the game.
