It has trouble with word problems, but if you can write down a word problem in math notation it shouldn't be an issue.

I also tried it on a weird fraction from an AP algebra exam, which it kind of failed at, but then I swiped over and it was showing me this graph, which included the correct answer: I love this app, not just because it would've helped 8th grade Paul out of a jam, but because it's such a computery use of computers.

On about half the middle school science problems I tried, the app was able to identify the topic at question and show me additional resources about the concepts involved, but for others it was no more powerful than a simple web search.

But for algebra this thing is I pointed it at 2x 2 = 7x - 5, which I wrote down at random, and it gave me a 10 step process that results in x = 7/5.

You use the tiny computer in your pocket to be basically smarter than you already are.

It's technology that augments a human brain, not just a distraction.

Typical phrases that indicate an Optimization problem include: Before you can look for that max/min value, you first have to develop the function that you’re going to optimize.

There are thus two distinct Stages to completely solve these problems—something most students don’t initially realize [Ref]. Now maximize or minimize the function you just developed.

For instance, a few weeks ago you could have gotten this as a standard max/min homework problem: You would probably automatically find the derivative $A'(r)$ (which you could equivalently write as $\dfrac)$, then find the critical points, then determine whether each represents a maximum or a minimum for the function, and so forth.

That’s exactly what we’re now going to do in Stage II. ) Remember that is just a constant — it’s some number, like 355.
