So I had this: 7*8+x*6*1+x*x At this point it's unclear what I should do.

So I had this: 7*8+x*6*1+x*x At this point it's unclear what I should do. I dragged the 8 on top of the * and that didn't seem to do anything. I dragged it onto the 7 and it asked what it should be. I said "56", but it put "56.0" for some reason. I dragged the 1 onto the x, and replaced that with "x", and now this is as simple as it can be, really. But no, it seems to want more. It seems it wants the "x * x" turned into x^2, which isn't necessarily simpler. I could find no way to factor out the "x"s, even though for some purposes that's simpler. I can certainly find no way of converting x*6*9+x*x into x(x+54) even though that's the simplest form. And if you say that you want standard form, why is x*54+x^2 the standard form, and not: x^2 + 54x which every mathematician would prefer. As I say, I find it an exercise in frustration, rather than enabling in any sense. If it were clearer what was the target then it might be better, but I don't know what it's trying to achieve.
