Number Quiz!

[650lb Sumo]

Can you name these categories/sequences of numbers?

(1) Divisible by two; Indivisible by two (Two Marks)
(2) Numbers which can only be divided by themselves and 1; Numbers which can be divided by more numbers than just themselves and 1 (Two Marks)
(3) Square roots of negative numbers
(4) 1, 1, 2, 3, 5, 8 etc.
(5) In 2/5, what are 2 and 5? (Two Marks)

(6) Numbers which can be written with a set number of decimal places; Numbers which can't (Two Marks)
(7) 1, 3, 6, 10, 15 etc.
(8) Why is 1.618... significant?
(9) What is special about 2,520?
(10) What is 3.1416... and what does it represent? (Two Marks)

Spoiler: Answers

(1) Even, Odd (used some simple definitions in this quiz)
(2) Primes, Composites
(3) Imaginary Numbers
(4) Fibonacci Sequence
(5) Numerator and Denominator

(6) Rational and Irrational
(7) Triangular Numbers
(8) It's the Golden Ratio.
(9) It's the smallest number divisible by all integers 1 to 10.
(10) π is the ratio of a circle's circumference to its diameter.

The pass mark is 8/15! How did you do?

Wow, this is the first time I actually passed one of these quizzes. And I barely passed with 8 marks.

I got 18 because I’m so good at the maths

1. Even and odd
2. Prime numbers, and numbers no long in their prime
3. Imaginary numbers, like most men and women's body count.
4. 13, Fibonacci sequence, I use this to fall asleep sometimes.
5. Numerator denominator
6. Men and Women
7. 21, triangles are a number sequence
8. Golden
9.
10. Pie, The Never Ending Story of mathematics.

He may be illiterate, but guy can solve the quotient with the best of them.

 

[HeffDoesWant]

9.

 

[Slapjit]

Oho ji... only number 9 I miss got 14/15 Waheguru watching and mummy ji already warming up chappal always full marks or full punishment haanji

 

[HUGHPHUG]

I just like to tell you all to go fuck yourselves

 

[ChickenBrother]

8/15 barely passed but this is a subject I should have scored higher on. At least I still remember some of my basic math(s).

 

[milliniar]

8 forgot some terms been out of school too long lol

I missed composites and "traingular numbers"

Anyone have a working explanation for those without copy pasting something? I don't even remember hearing that term before, though the calculation for the sequence generation is easily understood.

Took me a few tries to remember 2,520 first thought it was some special number squared, then thought it was adding up the angles of some special polygon, then thought of the actual answer third. Fun quiz!

Imagine you have lots of pool balls. With square numbers you can make squares. With cube numbers you can make cubes. With triangular numbers you can make (equilateral) triangles.

The complex stuff involving triangular numbers I don't remember and would have to look up.

I did not pass (6) but when I read the answers I remembered all of them but Triangular numbers. Never remembered that. Also never knew 2540.
