Arithmetic and algebra expressions:
Positive integer: Positive integers or natural numbers are numbers that are written only by using the combination of the ten existing
digits (0; 1; 2; 3; 4; 5; 6; 7; 8; 9). The natural numbers are infinite, we cannot list them all.
The first number that is a natural number is 0.
Rational number: Rational numbers are numbers we can write them as fractions that the numerators are
relative integers and the denominators are whole numbers different from zero.
Fraction: A fraction is a division where the dividend is called the numerator and the divisor is called the denominator.
Factors : A factor of a whole number is a positive integer that can divide that whole number, each whole number
has at least two factors.
Common factors: If a natural number divides two numbers by giving an integer quotient and zero remainder then that
natural number is a common factor or common divisor of the two numbers.
Prime factors: A prime factor of a whole number is its factor that is a prime number.
Composite numbers: a composite number is a natural number that is not a prime number.
Even numbers: An even number is a positive integer that is divisible by 2.
Odd numbers: An odd number is a positive integer that is not divisible by 2.
Decimals : decimals are all numbers that can be written with a point or not, all natural number are decimals but
all decimal numbers are not natural numbers.
Substraction : a subtraction is one of the four arithmetic operations that allows you to tell the difference between two numbers.
Divisibility rules : a rule of divisibility helps to know if a natural number is divisible by another
natural number or not.
