1,61803...
2,71828...
3,14159...

Answer

Pi (π) is the ratio of a circle's circumference to its diameter, approximately equal to 3.14159... It is an irrational number.

Question 2

Question 2 : What do you call a number divisible only by 1 and itself?

Réponses possibles :

Nombre parfait
Nombre premier
Nombre composé
Nombre entier

Answer

A prime number is only divisible by 1 and itself. The first prime numbers are 2, 3, 5, 7, 11, 13...

Question 3

Question 3 : Which Greek mathematician is famous for his theorem about right triangles?

Réponses possibles :

Euclide

Question 4

Question 4 : What is the factorial of 5 (5!)?

Réponses possibles :

25
60
100
120

Answer

5! = 5 × 4 × 3 × 2 × 1 = 120. The factorial of a number is the product of all positive integers less than or equal to that number.

Question 5

Question 5 : What is the golden ratio, approximately equal to 1.618, called?

Réponses possibles :

Phi (φ)
Epsilon (ε)
Delta (δ)
Sigma (σ)

Answer

The golden ratio (φ or phi) ≈ 1.618 appears in nature, art, and architecture. It is related to the Fibonacci sequence.

Question 6

Question 6 : In the Fibonacci sequence, what number follows 8?

Réponses possibles :

11
13
15
16

Answer

The Fibonacci sequence: 1, 1, 2, 3, 5, 8, 13, 21... Each term is the sum of the two preceding ones. After 8 comes 5+8=13.

Question 7

Question 7 : What does the symbol ∞ represent in mathematics?

Réponses possibles :

Zéro
Pi
Infini
Somme

Answer

The symbol ∞ (lemniscate) represents infinity, introduced by John Wallis in 1655. It symbolizes a quantity without limit.

Question 8

Question 8 : What is the result of 2 to the power of 10 (2¹⁰)?

Réponses possibles :

512
1000
1024
2048

Answer

2¹⁰ = 1024. This is an important number in computing because computers work in base 2 (binary).

Question 9

Question 9 : Which mathematician invented calculus at the same time as Leibniz?

Réponses possibles :

Newton
Euler
Gauss
Fermat

Answer

Isaac Newton and Gottfried Leibniz developed calculus independently in the 17th century, creating a famous controversy.

Question 10

Question 10 : How many faces does a regular dodecahedron have?

Réponses possibles :

6
8
12
20

Answer

A regular dodecahedron has 12 pentagonal faces. It is one of the five Platonic solids.

Question 11

Question 11 : What do you call a number that equals the sum of its proper divisors (example: 6 = 1+2+3)?

Réponses possibles :

Nombre premier
Nombre composé
Nombre parfait
Nombre amical

Answer

A perfect number equals the sum of its proper divisors. The first ones are 6, 28, 496, 8128. They are related to Mersenne primes.

Question 12

Question 12 : What is the square root of 144?

Réponses possibles :

11
12
13
14

Answer

√144 = 12 because 12 × 12 = 144. 144 is a perfect square, the twelfth in the series 1, 4, 9, 16, 25, 36...

Question 13

Question 13 : Which theorem states that there are infinitely many prime numbers?

Réponses possibles :

Théorème de Fermat
Théorème d'Euclide
Théorème de Gauss
Théorème de Riemann

Answer

Euclid proved around 300 BC that there are infinitely many prime numbers. His proof by contradiction remains a classic in mathematics.

Question 14

Question 14 : In geometry, how many degrees is the sum of angles in a triangle?

Réponses possibles :

90°
180°
270°
360°

Answer

The sum of angles in a triangle in Euclidean geometry is always equal to 180°, regardless of the triangle's shape.

Question 15

Question 15 : What is Euler's number (e), the base of natural logarithms?

Réponses possibles :

1,41421...
1,61803...
2,71828...
3,14159...

Answer

Euler's number e ≈ 2.71828 is the base of natural logarithms. It is a fundamental constant in analysis, related to exponential growth.

Accepted Answer

Pythagoras (6th century BC) proved that in a right triangle, the square of the hypotenuse equals the sum of the squares of the other two sides.
