Question

what are the properties of real number​

Answer 1

Answer:

Property (a, b and c are real numbers, variables or algebraic expressions)

1. Distributive Property a • (b + c) = a • b + a • c

2. Commutative Property of Addition a + b = b + a

3. Commutative Property of Multiplication a • b = b • a

4. Associative Property of Addition a +(b + c) = (a + b) + c

$\huge\red{★ANSWER》}$

A real number is a value that represents a quantity along a continuous number line. Real numbers can be ordered. The symbol for the set of real numbers is script R, which is the letter R in the typeface "blackboard bold".

The real numbers include: counting (natural) numbers (N){1, 2, 3, ... },

whole numbers {0, 1, 2, 3, ... }, integers (Z){... , -3, -2, -1, 0, 1, 2, 3, ...},

rational numbers (Q) (such as -½, 6.25, rn3) and

irrational numbers (such as rn4).

FYI: The series of three dots ( ... ), seen within the sets above, is called an ellipsis.

As used in mathematics, the ellipsis means "and so forth".

The properties of the Real Number System will prove useful when working with equations, functions and formulas in Algebra, as they allow for the creation of equivalent expressions which will often aid in solving problems. In addition, they can be used to help explain or justify solutions.
