Dear Serbian Smartypants, I'm sure he only meant high school math class was the last time he had to use these concepts, not that it's where he first learned them all. Arrogance isn't attractive.

Feb 3, 2016

In the first place, Eurocrum, I'm a she not a he, and in the second place I was a social worker and then a stay-at-home mom, neither of which had a lot of call for math vocabulary, especially since my kids were brilliant and didn't need help with their homework. And in my younger days in the 1950s and '60s, many of those terms weren't taught until high school if even then. Some of the terms on here we were never taught - factorial, natural numbers, summation. I am amazed now to look at the math homework of my younger grandchildren. They are doing math we never heard of until higher grades. I think that's a great thing and I wish I'd had the chance to learn more. But there's no need for you to be arrogant because you know more than I do on the subject.

Level 71

Feb 3, 2016

I find most serbians are jerks. Relax serbians I am just making a callous generalization the way eurochem did. I only know one serb and he's pretty cool.

I really hope you realize that you all sound arrogant. It's these kind of comments that deter me from going on JetPunk. Most of it is just people saying their age and their time and bragging about it, people attacking others who said the wrong word and someone takes full offense for that, or some sexually biased crap that makes it look like users of JetPunk are sexually biased into thinking women aren't allowed to get 100% on a quiz. I'm not insulting Quizmaster and his policies, but I'm warning that even JetPunk can turn out like Facebook.

Level 31

Jun 23, 2022

poor serbian man just wanted to express his comments.

Level 58

Oct 17, 2013

"Quantity that represents both a speed and a direction" should be velocity, not vector.

Level 73

Oct 17, 2013

Velocity is a type of vector, I think.

Level 58

Oct 17, 2013

Yes, velocity is indeed a vector, but not every vector measures speed and direction. A vector could just as easily represent displacement (distance and direction) or acceleration and direction.

Level 83

Jun 23, 2015

Agree with Scuadrado - a vector is a magnitude and a direction, which can represent a number of real-world (and theoretical) phenomena - acceleration and force are two real-world examples.

Level ∞

Oct 17, 2013

Changed the answer to velocity.

Level 58

Oct 17, 2013

And velocity questions belong on a physics quiz not a math vocabulary quiz.

Level 54

Jan 27, 2014

Agree with martryn

Level 57

Jul 7, 2014

You could change the clue to read "magnitude" rather than speed. Then the correct answer would be vector.

Level 57

Aug 1, 2014

You could stop the circle-jerk of semantics and just take the quizzes. Obviously if you're that well informed, this quiz doesn't pose much of a challenge to you anyway.

Level 65

Jul 13, 2016

@PorcNBeanz

Physics is very similar to math, with a tad bit of science added in there, so I think it belongs there.

Level 59

Nov 3, 2016

Math and physics are one and the same. The only difference is that math isn't constrained by reality.

Level 67

Jun 9, 2018

Physics is a subset of maths.

Level 57

I'm here to scout out possible contestants in the next 'Nitpicker Elite' series and I'm having a field day...

Level 65

Oct 17, 2013

Lines are two-dimensional in and of themselves. Also complex numbers should be acceptable as well as imaginary numbers.

Level 59

Jan 9, 2014

"Lines are two-dimensional..."

No they aren't. :)

Level 47

Oct 30, 2014

points have no dimension, lines have one, and planes have two. Think of how many numbers it takes to specify your position if you were within the entity in question. You're either on the point or off it, so you don't need any number to tell you where you are; you can be on a line at point 4, or -36.845, or any spot specified by one number that tells you how far along you are; and the plane takes two numbers.

Level 45

Dec 20, 2015

Man, I was taught that a line was two dimensional in school. No wonder I turned out so bad at math!

Level 40

Jul 30, 2017

Well a straight line isn't! You'd need two dimensions to define a curve though.

Level 69

May 16, 2019

@GameKitty maybe what they were trying to say was that a line drawn on a board or on a piece of paper does in fact have some width (and technically some depth as well even though its just a layer of chalk or ink) which makes it kind of 2 dimensional. but the mathematical definition of a line is something that only has 1 dimension.

Level 45

Jul 17, 2014

How many sides does a circle have?

Two, silly, an inside and an outside!

Level 65

Jul 13, 2016

And that is exactly why they are two-dimensional.

Level 77

Feb 2, 2016

A plane is not really defined mathematically defined as a "two dimensional version of a line" but a flat, two-dimensional surface.

Level 59

Nov 3, 2016

A line is a one-dimensional surface, so it logically follows that a plane is a two-dimensional line.

Level 48

Jan 19, 2017

Amen to this. It is a two-dimensional surface. A line can be found on a plane. A line is NOT a plane.

Level 57

Feb 22, 2022

Think about it this way:

Line is to one dimension what plane is to two dimensions.

Level 59

Nov 3, 2016

The square root of a negative number is in fact complex, but so is the square root of a positive number, so that would be a really vague answer (like accepting "that one country" on the Countries of the World Quiz)

Level 62

Feb 2, 2023

Rubbish!

Level 50

Jan 25, 2021

Lines are one-dimensional

Level 62

Feb 2, 2023

If you square a complex number, you get another complex number, not a negative number.

Level 11

Oct 17, 2013

The mode isn't always the average. The average is the median. 2, 2, 4, 6, 8, 10, 12. The mode in that sequence is 2, but the average(median) is 6.

Level 72

Mar 31, 2014

"Type of average" != "average always." Please actually read carefully before commenting...

Level 59

Nov 3, 2016

There are multiple types of averages. There are the mode, median, arithmetic mean, geometric mean, harmonic mean, and possibly others I don't know about. None of them are THE average - they are all AN average.

Level 67

Jun 9, 2018

There are a great many different types of mean. Quadratic mean is probably most common after the ones you listed - you square all the data, take the arithmetic mean of that and then take the square root. E.g. To find the quadratic mean of 1, 2 and 2, you square then all: 1, 4, 4. Take the arithmetic mean of that: 3. Then take the square root: √3.

Level 67

Jun 9, 2018

In fact, given any smooth one-to-one function from the positive numbers to the positive numbers it is possible to construct a mean based on that function. The functions for different means are: Arithmetic Mean: f(x) = x; Geometric Mean: f(x) = log(x); Harmonic Mean: f(x) = 1/x; Quadratic Mean: f(x) = x^2.

Level 67

Jun 13, 2018

Actually any one-to-one smooth function from the positive numbers to the real numbers works, as log x will not always be positive.

Level 46

If you liked this one, see how many of the names of polygons you remember. http://www.jetpunk.com/user-quizzes/10371/name-that-polygon

Level 61

Oct 18, 2013

Could you accept "polyhedra"?

Level ∞

Oct 18, 2015

Okay

Level 52

Oct 18, 2013

To be pinickity, i is called THE imaginary number, and numbers of the form a + bi are complex numbers. So the answer "imaginary numbers", strictly speaking, is wrong. At least set it to accept complex numbers and I will be satisfied

Level 45

Oct 19, 2013

Actually, it's not wrong. You're correct that numbers of the form "a+bi" are called "complex numbers", but square roots of negative numbers take the form "bi" and are all called "imaginary numbers". i is the "imaginary unit".

Aren't square roots of negative umbers also called complex numbers?

Level 32

Oct 23, 2013

You should accept Platonic Solid for "...Tetrahedrons and Dodecahedrons...". I got so hung up on these being 2 of the 5 platonic solids that I figured I was spelling platonic wrong! Polyhedron is correct of course, this is just an alternative.

Level 82

Jun 9, 2014

Yes! Yes! Yes! Could not believe it was not taking platonic solid, but went on to try platonic regular solid, platonic forms, regular solid, etc.

Level 28

Aug 16, 2014

yes, this!

Level ∞

Oct 18, 2015

Platonic solid will work now

Level 74

Nov 3, 2016

"Perfect solid" should also be acceptable.

Level 75

Feb 2, 2016

Level 50

Jan 25, 2021

Level 59

Nov 3, 2016

Right triangle = triangle with one right angle...

Level 67

May 17, 2018

The term is not widely used in the UK. But I think the meaning is fairly clear.

Level 84

May 7, 2014

There is no such thing as the square root of negative numbers. The square root is a function defined from the positive numbers to the positive numbers. No analytic continuation to the negative number is regular. Imaginary numbers are numbers whose square is a negative number and no, it's not an equivalent definition.

Level 84

May 7, 2014

As for those who say the answer should be "complex numbers", that's wrong. The square of any complex number is a complex number (for example : (1+2i)²= -3 + 4i ). It's only the pure imaginary numbers that give negative numbers.

Level 75

Feb 2, 2016

Isn't it a complex number with zero real part?

Level 84

Feb 3, 2016

Not all complex numbers are imaginary, thus "complex number" can't be accepted for this question (which should still be corrected, by the way, everytime I read that, my eyes bleed).

Level 67

May 17, 2018

Technically I think Arp is correct. In the field of complex numbers for every complex number z there are actually two complex numbers a such that a^2 = z. In the case of -1 these numbers are i and -i. It is possible to define a function, however, that is defined from the complex numbers to the complex numbers that could reasonably be called a square root - and it is the solution x to the equation x^2 - z = 0 with either the greater real part of if both real parts are the same the greater imaginary part.

Level 82

Jun 9, 2014

Perhaps reflects my advanced age, but we learned the positive integers as 'counting numbers'. Counting number in wikipedia redirects to natural numbers. COuld you add that in? And as mentioned above, please accept platonic solid - or make one of your examples an irregular polyhedron.

Level 47

Oct 30, 2014

I tried "counting numbers," too. Never did get to "natural numbers."

Level 50

Jun 23, 2015

As a math major, I'm depressed that I missed one. I haven't used scalene triangles in quite a while though, to be fair.

Level 59

Nov 3, 2016

Stuff like "scalene" is useless vocabulary that you shouldn't need to know; you just need to know the actual math behind it. Whoever thought they had to create some fancy word just to define a triangle with sides of different lengths was out of their mind.

Level 62

Jun 23, 2015

In the expression a/b=c; c is called the quotient; a is called the dividend, and b is called the divisor, a is also called the numerator and b is also called the denominator.

Quizmaster should accept divisor as well as denominator.

Tetrahedrons and dodecahedrons are actually "regular polyhedrons," since they both have congruent edges and faces, and only a few other polyhedrons fall into that category. Please accept that answer as well.

Level 86

Feb 2, 2016

Fun quiz. The bottom number in a fraction can also be called the divisor. Perhaps you should accept this as well?

Level 87

Feb 2, 2016

Please accept counting numbers. Many include 0 in the definition of natural numbers, but counting numbers can only be nonnegative.

Level 59

Natural numbers never include zero

Level 76

Jan 19, 2017

0 is included in whole numbers, not natural numbers.

Level 76

Aug 4, 2022

I've heard it both ways. Natural numbers usually include 0 in theoretical computer science especially. In my experience people use the term "positive integers" when they want to exclude 0.

Level 75

Apr 8, 2020

Some mathematicians consider zero a to be a natural number, others don't.

Level 84

Feb 2, 2016

Sorry to repeat myself, but seriously, an imaginary number is a number whose square is a negative number, not the "square root of a negative number". That may seem to be equivalent, but it's not. Of course, you have to know a bit about functions to understand that...

Level 59

Nov 3, 2016

Of course, it actually is equivalent. This is a commonly accepted fact that is taught everywhere. Every number has two roots, and every negative number has roots that are imaginary.

Level 67

Jun 22, 2018

You can define a square root of k as a root of the equation x^2 - k = 0. Then imaginary numbers are square roots of negative numbers. A square root is not always a function.

Level 84

Feb 2, 2016

I also don't like that definition of a prime number, because it doesn't clearly exclude the case of 1 ( 1 is NOT a prime number ). The correct, though less explicit definition, is simply to say that a prime number is a number with exactly two positive divisors...

Level 62

1/20. Would have scored 6/20 had I been able to answer in Dutch. Mathematics was never one of my fortes...

Level 32

Feb 5, 2016

3.14 should be accepted for "Pi", as well as,"median" for most common value in a set, and maybe "vertix" for vertex and "Hypothenuse"

Level 59

Nov 3, 2016

Now, on the other hand, a much better approximation would be 16*arctan(1/5) - 4*arctan(1/239).

Level 75

Apr 8, 2020

The median is not the most common value in a set. Mode is the only correct answer.

I would like to add to the cause of counting numbers. It's been nearly 30 years but I distinctly remember those terms being synonymous and the world of google tends to agree.

Level 59

Nov 3, 2016

I would consider adding "square" for two-dimensional line. I've spent some time learning about hypercubes, and the example everybody always uses is that a point is 0 dimensions, a line is 1, a square is 2, and a cube is 3. Going off of this example, the logical answer for "two dimensional line" would be a square. I eventually did get plane as the right answer, but I still think square should be added as a type-in.

Level 67

May 17, 2018

Technically you should replace line with "lime segment".

To be pedantic, a "Three-dimensional version of a circle" is a 3-sphere (a 3-dimensional hypersphere). A normal sphere has only two dimensions: e.g. latitude and longitude. While spheres are often embedded in 3-dimensional space you can also embed a sphere in 4-dimensional space, so it's not really saying much.

Level 67

May 17, 2018

A circle is defined as the set of all points in a plane that are a fixed distance from its centre. A sphere is the logical continuation replacing a plane with 3-dimensional space. You can embed a sphere in 4-dimensional space but it will no longer be the set of all points a fixed distance from the centre.

Level 59

Sep 14, 2018

The original commenter is technically correct; an ordinary "sphere" is actually a 2-sphere, a 2-dimensional surface embedded in 3-dimensional space. A 3-sphere would actually be embedded in a 4-dimensional space. A more accurate answer would probably be "ball," which refers to not only the sphere but also the space enclosed by the sphere.

Level 67

Sep 15, 2018

That is the case in topology. But the most natural definition for a circle in Euclidean geometry requires two dimensions, and a sphere would be the result in three dimensions. The circle itself, though, is I suppose one-dimensional. A ball would be the three-dimensional equivalent of a disc.

Level 87

May 17, 2018

Typed 1 with 100 zeroes and it didn't work. Disappointed.

Level 29

May 17, 2018

A two-dimensional version of a line is a line. Did you mean 3 dimensional?

Level 67

May 18, 2018

A line is one-dimensional. A two-dimensional shape has the up-down and the left-right dimension, but a line only has one: along the line.

Level 66

Jul 14, 2019

think of length height and width. A line only has length. A sheet got two of those and a wooden beam for instance has all 3.

Level 45

May 17, 2018

Hmm, hard when you're not native English. Got 16/20, but I was typing 'regular solids', 'faculty, facultation'. 'irreal numbers, complex numbers'. Never heard of Scalene.

Jun 27, 2018

Got all of them first try, lol, I'm a math nerd.

Level 59

Sep 14, 2018

Strictly speaking, the object commonly referred to as a sphere is only two-dimensional (while a circle has only one dimension). The answer "ball" should also be accepted; the space bounded by a 2-sphere constitutes a three-dimensional ball: https://en.wikipedia.org/wiki/Ball_(mathematics)

Level 27

Nov 30, 2018

the question "two-dimensional version of a line" is incorrect because a line is already in two space, whereas a plane is only used in 3-space.

Level 67

Feb 15, 2019

2-space is a plane.

Level 66

Jul 14, 2019

A plane is on x and y axis, and zero on z axis. It has no vertical height.

Level 93

Dec 19, 2018

Please consider accepting "cylinder" for "three-dimensional representation of a circle." I understand why sphere is more widely answered, but I would argue that not only is a cylinder a three-dimensional representation of a circle, but that it is also a better answer to the question as it really only is a circle extruded over a third dimension rather than a circle rotated around an axis.

Level 67

Feb 15, 2019

A circle is defined in 2-dimensional space as the set of all points that are a given distance from the circle's centre. If you replace 2-dimensional space by 3-dimensional space you get a sphere.

Add depth to the circle to get a cylinder. Add depth to a square and you don't always get a cube. It can be a rectanguloid. "3-D circle" is not good enough.

complex numbers is also an acceptable answer for square root of negative numbers

Imaginary numbers are a subset of the complex numbers. No complex numbers that are not also imaginary numbers are ever square roots of negative real numbers. So imaginary numbers are the correct answer.

Would you consider accepting 'counting numbers' along with 'natural numbers'? Thanks for checking.

This is not a very well informed math quiz. Even after years and years, its still not good.

1) A three dimensional version of a circle doesn't have to be a sphere. It could be a cylinder

2) I would argue that a "two-dimensional line" is a line.
