About Number Properties
Number properties are rules and characteristics that help us work with and understand numbers in mathematics. These properties make it easier for us to perform operations like addition, subtraction, multiplication, and division. We’ll cover some essential number properties in this article, including the commutative, associative, distributive, and identity properties.
What are Number Properties?
Number properties are basic rules that describe how numbers behave in mathematical operations. By learning these properties, we can better understand how to work with numbers and solve math problems efficiently.
Commutative Property
The commutative property states that the order of numbers in addition or multiplication does not affect the result. In other words, changing the order of numbers won’t change the answer. This property applies to both addition and multiplication, but not to subtraction or division.
For example:
- For addition: 5 + 3 = 3 + 5
- For multiplication: 4 × 7 = 7 × 4
Associative Property
The associative property tells us that when adding or multiplying three or more numbers, the way we group them does not affect the result. Like the commutative property, this rule applies only to addition and multiplication, not subtraction or division.
For example:
- For addition: (2 + 3) + 4 = 2 + (3 + 4)
- For multiplication: (6 × 2) × 3 = 6 × (2 × 3)
Distributive Property
The distributive property states that when a number is multiplied by the sum of two other numbers, it’s the same as multiplying the number by each of the two numbers and then adding the results. This property is particularly useful when simplifying expressions in algebra.
For example: 5 × (3 + 2) = (5 × 3) + (5 × 2)
Identity Property
The identity property defines special numbers called “identity elements” that, when combined with other numbers through certain operations, do not change the value of the other numbers. For addition, the identity element is 0, and for multiplication, it’s 1.
For example:
- For addition: 7 + 0 = 7
- For multiplication: 9 × 1 = 9
Distributive Property of Multiplication Over Addition
The distributive property of multiplication over addition is another way to describe the distributive property. It emphasizes that multiplication distributes over addition, as we saw in the previous example.
For example: 4 × (6 + 3) = (4 × 6) + (4 × 3)
Formula Chart of Basic Number Properties
Here’s a quick reference chart with the basic number properties and their formulas:
- Commutative Property
- Addition: a + b = b + a
- Multiplication: a × b = b × a
- Associative Property
- Addition: (a + b) + c = a + (b + c)
- Multiplication: (a × b) × c = a × (b × c)
- Distributive Property
- a × (b + c) = (a × b) + (a × c)
- Identity Property
- Addition: a + 0 = a
- Multiplication: a × 1 = a
Solved Examples of Number Properties
- Commutative Property:
- 8 + 12 = 12 + 8 (Addition)
- 9 × 5 = 5 × 9 (Multiplication)
- Associative Property:
- (7 + 6) + 4 = 7 + (6 + 4) (Addition)
- (3 × 8) × 2 = 3 × (8 × 2) (Multiplication)
- Distributive Property:
- 6 × (4 + 10) = (6 × 4) + (6 × 10)
- Identity Property:
- 15 + 0 = 15 (Addition)
- 11 × 1 = 11 (Multiplication)
Practice Problems of Number Properties
- Apply the commutative property to the following numbers:
- 7 + 9
- 6 × 4
- Apply the associative property to the following numbers:
- (2 + 8) + 5
- (10 × 3) × 7
- Apply the distributive property to the following numbers:
- 3 × (6 + 4)
- Identify the identity elements in the following problems:
- 13 + ?
- 5 × ?
Fun Facts!
- The word “commutative” comes from the Latin word “commutare,” which means “to change” or “to exchange.”
- The associative property is named after the word “associate,” which means “to group” or “to connect.”
- Identity elements are unique to each operation: 0 is the identity element for addition, and 1 is the identity element for multiplication.
