No maths grad here and got 17/19. I didn't see anything beyond GCSE-level maths or general knowledge. (Apart from the quiz thumbnail image!)

Guessed "Euclid" for "e" number and missed the 1 thru 100 summation (despite previously seeing comments in other quizzes on the Gauss series formula: sum = n(n+1)/2 with n=100 returns 5050 :o)

The only ones that were a bit tricky really were the e one, which I only knew because it was part of a question on Trivial Warfare recently, and the sum of the numbers 1 through 100. I didn't know the formula for that, but I reasoned the 1+100=101, 2+99=101, 3+98=101, etc., so I multiplied 101*50.

I think I'm going to have to agree with you there. I got 13. I'm not necessary a "math guy", but I've delt with math quite a bit and thought I had done pretty well all things considered. I think I would have done a little better with more time (some of them were coming to me as a dredged through the memory banks). But I certainly believe that there are plenty of people that have google open on another tab as they take these quizzes.

Please accept "base 2" instead of binary. I don't know if I am right, although Wikipedia suggests I am, but when I think of a numbering system, I think of base 2, but when I think of the results of the system, I think of a binary number.

In any event,base-2 is certainly a correct answer to the question you asked.

Seconds and hours are purely physical definitions. Thus this question has nothing to do with mathematics. While the same holds for the "meter", the relation between "centi" and "kilo" indeed relates to mathematics. Just said. Further, with the non-metric system used in parts of the world, it appears to be an accident that all countries use the same units of time. ;-)

I'm curious how you think someone would answer the question "How many seconds are in an hour?" without using math. True, you could just know it off the top of your head, but I think most people would say, "Okay, 60 minutes in an hour and 60 seconds in a minute, so the answer is 60 * 60."

I think s/he means that you can just as easily ask 'how many players are on a football team' or 'how many objects do you see in this image' and it would be the same sort of question i.e. arbitrary counting using definitions set by people as opposed to pure unadulterated unbiased 'mathematics'. Although I do agree with you, most people will use mental maths to solve this, so I'd say it's still fitting.

I suppose if you wanted to make it more obviously mathy (mathsy?) you could change it to "seconds in a day" or "seconds in a week" or something like that, because there are some people who just have the number of seconds in an hour memorized. Don't do "minutes in a year," though, because then it's definitely a music question, not a math question.

If you go down that road, you'll end up in a place in which none of the questions is really mathematics enough. After all, Pythagoras is just an old Greek dude and the formula would have worked no matter who discovered it. So it's a history question.

To find out the sum of all the numbers in any set that increases at regular intervals (eg., each number is 1 higher than the one before it, or each number is 5 higher than the number before it), just add the lowest and highest numbers, then divide by 2. Take your answer, and multiply it by the number of terms in the set. So, in this case, there are 100 numbers (or "terms"), increasing by 1 each time. Add the high and the low: 1+100=101. Divide by 2: 50.5 (this answer will also be the average of all the numbers in the set). Then multiply that number (50.5) by the number of terms in the set (i.e., 100). So, 50.5 x 100 = 5050.

An easy way to see the answer it to separate the sum into two parts:

1+2+...+50

100+99+...+51

then adding the terms two by two: 1+100 , 2+99, ..., 50+51 , one obtains 50 times 101 = 5050.

I think you mean complex rather than imaginary. It may a translation issue; in French for instance, "imaginary numbers" are called "pure imaginary numbers" to distinguish them from "complex numbers", as those were originally simply called "imaginary numbers".

I agree with you, the 3 numbers can be described as real and complex. The hint is a bit confusing.

A certain amount of common sense can be required--remember, the instructions on Jetpunk's quizzes always ask if you can guess an answer based on a hint; it never says "Each of these answers has one unique, correct, answer: provide it."

In this case, yes, they are real numbers; but what is the motivation for listing them, if the answer is "real numbers"? None--they are not better exemplars of real numbers than any other.

But they are, famously, irrational and proofs of their irrationality is usually part of a math curriculum; high school math students are likely to see a proof of √2's irrationality. So irrational is obviously the best and intended answer, even if there are other strictly correct ones.

I do think it's slightly weird to spell "Pi" and not use π, it kind of implies you're referring to the letter and not the constant, but it's still clear what's being asked for.

All three of the questions about stuff named after mathematicians ask for the mathematician rather than the item. It's not "Euler's number" about e, and "sequence" is already filled in for "Fibonacci". So it's nicely self-consistent in the quiz.
