polynomial
polynôme m

Polynomial. An algebraic expression that contains only positive bases (powers) of a variable or more than x and y . . . For example:

3x²+5x+1
quadratic is a quadratic polynomial

yu23+7y+2
is a cubic polynomial

1 + 3xy + 2y3x2
is a polynomial of degree 5

In the polynomial 7x - 6 + 3X2 + 5X4 the number

multiplied by (x4) is called a coefficient of the quantity x4 .

population
population f

A population. A statistical term referring to a group of

things for which a particular characteristic is being measured. Populations can be finite or infinite.

positive
positif

Positive. Positive. A positive number is a number whose value is greater than zero. For example:

All the numbers 735 - 31/4 - 0.1 are positive numbers.

The numbers - 3,5, -2, 0 are not positive.

pound
livre f

Pound. 1 - A unit of currency (also called "pound" in Arabic). One pound equals (1) 100 pence. 2 - A unit of weight. A pound equals 16 ounces. Every 14 pounds equals one stone. A kilogram equals about 2.2 pounds.

power
power f

Power. For example: 2 raised to the 4th power (written

24)=2×2×16 = 2 and 3 raised to the 2nd power is written as 32) 3×9=3
Any number raised to the 2nd power is called a square, and any number raised to the 3rd power is called a cube.

prime
primaire

Prime. A prime number is a number that has two factors, namely 1 and the number itself. There are an infinite number of prime numbers. For example: 2, 3, 5, 7, 11, 13, 17, 19, etc.

Note that 2 is the only double prime number.

prism
prisme m

Prism. A prism is a polyhedron that has the same cross section along its length.

The volume of a prism can be found by multiplying the cross section area by the length of the prism.

probability
probabilité f

Probability Probability is a measure of the likelihood of an event occurring. The value of probability ranges from 0 (impossibility of the event) to 1 (certain event). For example:

The probability of the sun rising from the east = 1.

The probability of Sunday coming after Monday = 0.

The probability of a head (tails) appearing when tossing a coin = 0.5

In cases where there are several equal outcomes, the probability of a particular event is measured as follows:

The number of events that are in favor of the outcome / the total number of possible events

product
produit m

The product (product) of two or more numbers is

The product of multiplying these numbers together

each other. For example:

9 16 35 )1322( The product of matrices (1) and (12) is

The product of 2, 3 and 4 is 2×3×24 = 4

The product of 6 and 11 is 6×66 = 11
The product of the two matrices
