Set: A collection of objects.
Point: This may be represented by a dot on a piece of paper and is usually named by a capital letter. This has no length, width, or thickness. It indicates only place or position.
Line: This is a set of points. This may form a curved line or a straight line. Unless otherwise stated, the term line will mean a straight line.
Plane: A set of points that form a flat surface extending indefinitely in all directions.
Closure Property of Addition: This property states that sum of two real numbers is a real number.
Closure Property of Multiplication: This property states that the product of two real numbers is a real number.
Commutative Property of Addition: This property states that when two real numbers are added, the order in which they are added can be changed without changing the sum.
Commutative Property of Multiplication: This property states that when two numbers are multiplied, the order in which of the factors can be changed.
Associative Property of Addition: This property states that when three numbers are added, the sum does not depend on which two numbers are added first.
Associative Property of Addition: This property states that when three numbers are multiplied, the product does not depend on which two numbers are multiplied first.
Identity Property: This property states that any real number added to any real number(a), the sum is a.
Multiplicative Property: This property states that when 1 is multiplied by any real number(a), the product is a.
Additive Inverses: Two real numbers are called this if their sum is the additive identity, 0.
Multiplicative Inverses: Two real numbers are called this if their product is the multiplicative identity, 1.
Distributive Property: This property combines the operations of multiplication and addition. Multiplication distributes over addition.
Multiplication Property Of Zero: This property defines multiplication of a real number by zero as zero.
