While testing the solution for #34 on an iPad (the specific device was an iPad 2 labeled "Witten"), I found that combining the squared terms on the "Explore" screen wasn't working properly. If I drag out an x-squared term, drop it, then try to combine it with and x-squared-y-squared term, the expression hints don't show up, and dropping the second term next to the first doesn't result in an expression being formed. This does not occur on my desktop running Chrome, even when done using the touch screen.
