	Very good quiz! Took me a minute to understand, but the time limit is reasonable and a great idea.

	Cool quiz. 8^3 took me too long. Please make many more.

	Hmmm, are there many taking the test multiple times? 24% get all 30 correct in the allotted time? I got to the beginning of the Grab Bag and was shocked to see how low a percentile I fell in. Took it again, (now knowing all answers) and still missed the last one before timing out. Only 76th percentile. Great quiz...I need to do one-a-day!

	Nice divergence from the typical qualitative quiz.

	That "to the .5 power" one flummoxed me.

	Interesting game. It was easy for me because I was a freakin' math major, but I like the idea, and I liked the little twists (throwing in a ^.5 and ^0, for example).

	@Commodore, at a guess there's a high number who fall at 10/0.25

	Looks like we all crossed a culture barrier today. "Math" vs "Maths" or never shortening "Mathematics". As a lazy person and not just as an American, I'm going with the least syllables and the fewest letters, math it remains for me. Show me an equivalent where the Brits have the shorter pronunciation and i'll gladly convert.

	@ SowCrates: I'm interested to know how you speak, if you think math has less syllables than maths - they both have one syllable when I say them! I'm British so would always use maths, but I'm certainly familiar enough with American culture not to be confused by the usage of math, or bother whinging about it...

	wow - great quiz - what a race against the clock!

	Fun - I take pride in being good at basic math (to make up for how bad I am at higher-level math). I got them all except section five, which I got flustered on and couldn't finish. I'd love to see more of these.

	why do people think it should be maths?! do you guys shorten economics by writing econs? of course, hence why mathematics is totally acceptable abbreviated as math

	terpfan417:	Nov 4th, 2009 at 18:05 GMT	4 points
	I liked that. Wasted too much time on 8^3.

	unc_rameses:	Nov 4th, 2009 at 18:10 GMT	10 points
	Only one problem with the quiz: you can answer with the negative of the absolute value of an answer and it is still counted as correct! (Don't ask me how I figured that out...it's sort of embarrassing)

	sss:	Nov 4th, 2009 at 18:43 GMT	4 points
	@ unc_rameses: unfortunately that's a limitation of the Sporcle code; it strips all non-alphabetic characters, spaces and common words like 'and' and 'the' before comparing the input to the answer. Bit annoying, but still a good quiz. Re my previous comment, are there more than one of you out there that view 'maths' as a polysyllabic word then?!

	pbysr:	Nov 4th, 2009 at 18:49 GMT	7 points
	Sowcrates clearly wrote "least syllables and fewest letters." Maths=5 letters. Math=4 letters.

	sss:	Nov 4th, 2009 at 18:58 GMT	0 points
	...and mentioned 'shorter pronunciation'. They're equivalent, is all I was saying. And typing an extra letter isn't really anything to get upset about, although thanks for counting them for me, I don't think I could've managed that.

	-15*4 is definitely -60, so he got it right. Good work. Also 3^4 and (-3)^4 are both 81, so that wouldn't matter anyway.

	janwillemvandijk:	Nov 4th, 2009 at 19:25 GMT	18 points
	nice one. Sheesh, got 100% but boy did I have to think hard on a couple of those questions. @memphis: -154 = -60; where did you get the idea that -15-15-15-15 (-154) is +60? If you still think you are right, then you won't mind agreeing upon receiving -15*4 USD from me. I'll send you my bank details when you've figured it out.

	Wow this was a great challenge - much more so than that Easy Math quiz over in the user section. Great job!

	HalfWelsh:	Nov 4th, 2009 at 19:32 GMT	15 points
	WHAT?? how is -15*4 positive? negative times positive is negative. I don't know what's worse, that you got that wrong or that you felt the need to tell us all that you are wrong!

	I love when arithmetic is considered "difficult" math.
