	It's counting both archived and current comments.

	I like the time, by the way. It's one of those quizzes that, since it's basically a computation race, if more than 5% of the people get all of them, then there's too much time.

	I agree with shawnoc that the time is good. Unfortunately, I didn't get into my "mojo" until only 30 seconds were left and I failed.

	Math major, but in 3 minutes I only got through 2^27. I even got through the 1-10 ^ 1-10 quiz with time to spare. This one is hard.

	@RainmanDX don't worry, having a major in maths doesn't necessarily mean you are good at mental arithmetic, ask any bookie.

	this should have a sequel: "powers of 1"

	Maths FTW!

	With all the quizzes, I try again and again and push myself to do better (without cheating)(ever), but I think this is the first time I've ever hit a wall in my Sporcling career. I got up to 2^24 on my first try, then I tried again, and got 26, then 28, then 29, and then 29, and then 29, and then 29 again. I am mentally incapable of pushing any further than twenty-ninth power. The experience is humbling, and sad, but also quite satisfying. I have a quiz I cannot conquer but wish I could.

	My strategy was just more or less memorizing all the numbers up to 2^26 (67,108,864), then I had do the arithmetic from that point on. I remember when I was little, out of boredom, I would frequently compute 1+1=2, 2+2=4, 4+4=8, etc. with my first eight-digit calculator until it said "Error."

	why oh why are 1 and 2 not the most correctly guessed answers? In the voice of GOB, "COME ON!!"

	mjenks:	Dec 9th, 2009 at 15:54 GMT	3 points
	Wow, and I thought memorizing 2^20 would only come in handy when taking NMRs.

	MagicFingers:	Dec 9th, 2009 at 16:56 GMT	2 points
	Brain hurts, but it was actually fun haha! Got to 20
