I have never seen an app like this. It seems as if this app was tailored just for me. Overall this is an exceptionally wonderful app.

Although I have given positive reviews to wolfram apps over the years, I must say that the advertising on the start-up screen is offensive. I have not seen this from any other company. For the future great mathematicians that will be here in 20 years, I would sleep easier had they started their math career using pencils and reams of graph paper. As it is now, we will lose in the long run to countries that are too poor to provide computers or iPads to their children. Perhaps, for every child that uses this app, Wolfram could donate a package containing a variety of graph paper for them to xerox and use in their pursuit of math perfection.

I've been using this app during Dad and Daughter Math Night with my 10yo. We're using it to explore topics that are part of her regular math class, often ahead of the class. I think it's terrific. You should know that this is basically a learner-friendly front end to Wolfram Alpha, which in turn incorporates many of the functions of Mathematica (a high end professional math tool). So there's a natural progression from pre-algebra through the other wolfram apps to Mathematica (of course by 2022 who knows what kids will use). It requires a data connection to work. The only downside is that nobody yet provides a math curriculum based on this tool. That's what we need to give it five stars. I'm surprised that hasn't happened yet, it would make a great eBook.

My one complaint is that apparently when you ask the program to calculate Mean, Median, & Mode for a string of numbers you must re-enter the number string for each answer. I would expect you should be able to enter the number string once and have the program spit out all 3 answers at the same time.

I wanted an app that I could recommend to my students who needed a review or tutoring...this is NOT that...this app does the work for them. That said, it is slick and well laid out.

It does not calculate the surface area of a cone!
