Interesting article. I ran across a problem yesterday that was similar to P(x)^Q(x) = 1, which then asked me to find the sum of the solutions. I noticed that both P(x) and Q(x) share a root at some a. But I realized, 0^0 is most often defined as 1, and carried on. Checking the answer key later on showed that they chose to neglect that a, and call 0^0 undefined. I'm not sure how I really felt about it.

Note, I also forgot to check when P(x) = -1, assuming that Q(x) is even there ;P

In America there are colleges, and there are universities. We usually refer to community colleges and state colleges as, well college. Then the Ivy League and prestigious universities, are, well referred to as universities. But they are pretty much used interchangeably. Don't stress the difference.

I've seen this problem many times, and I've always fixed it by plugging the device into iTunes and there's been a button that literally says "Enable WiFi on this device".
