Recognizing Patterns in Real Numbers (Properties)
Math in short is a representatin of a pattern! in a continuation of our review section we are going to be discussing being able to recognize some of those patterns also known as Properties.There are 5 basic Properties that we are going to discuss, Associative, Commutative, Distributive, Identity , Inverse. Please see below for a breakdown.
Associative
- Addition
- Multiplication
Associative
- This property simply means that rearranging the grouping in which the numbers or letters are placed has no affect on the sun, if additive, or the product, if multiplication.
Associative
- Addition: b + ( x + n ) = n + ( x + b )
- Multiplication: -n * ( b * x ) = ( b * – n ) * x
Commutative
- Addition
- Multiplication
Commutative
- This property simply means that rearranging the order in which the numbers or letters are placed has no affect on the sun, if additive, or the product, if multiplication.
Commutative
- Addition: x + n = n + x
- Multiplication: nx = x*n
Distributive
Distributive
- In this property it simply means that a real number will be distributed over the addition in the equation. This is also true for subtraction.
Distributive
- Addition: x * ( b + n ) = x * b + x * n
- Subtraction: x * ( b – n ) = x * b – x * n
Identity
- Addition
- Multiplication
Identity
- In this property the deletion of zero makes no difference in the sum. this is the Additive Identity.
- In this property the deletion of one makes no difference in the product. This is the Multiplication Identity.
Identity
- Addition: 0 + b = b
- Multiplication: bx * 1 = bx
Inverse
- Addition
- Multiplication
Inverse
- In the Addition Inverse Property the sum of a real number and its inverse will equal zero.
- In the Multiplication Inverse Property the product of a real number large than zero and it’s inverse will produce 1.
Inverse
- Addition: x + -x = 0
- Multiplication: x * (1/x) = 1
