Distributive Property: Definition, Formula, Examples

Distributive Property: Definition, Formula, Examples – The distributive property is a well-known property related to numbers and algebra in mathematics. As the name suggests, this property focuses on distributing or dividing a quantity through proper conditions. The distributive property or distributive law is only operated in the multiplication of numbers and algebra. This is why it is also called the distributive law of multiplication.

Note: Distributive property can never be applied in the addition or subtraction of numbers. Even if you apply, the result will be void or produce errors in the solution.

Before diving deep into multiplication’s distributive property, let us have a quick look at other important properties in mathematics. They are listed below:

  • Commutative Property: This property states that the numbers or terms can commute or move their places in the expression without altering the result. This is true for addition and multiplication. For instance, (1 + 4) = (4 + 1) and (2 * 4) = (4 * 2). Subtraction doesn’t follow this property, for example, (1 – 4) = -3 is not equal to  (4 – 1) = 3.
  • Associative Property: This property states that the number of terms in an expression can associate themselves or groups with each other without altering the result. This is true for addition and multiplication. For instance (1 + 4) + 3 = 1 + (4 + 3).

Let us now discuss what distributive property means and examples.

Distributive Property Definition

Let us first understand a simple concept. If you have to distribute something, let’s say chocolate, with your friends, you divide the chocolate bar into pieces to ease the distribution, right! Mathematics follows the same concepts. When we have to simplify a hard problem, the distributive property helps to break down the expression into a sum or a difference of 2 numbers.

Mathematically the distributive property states that any expression provided in the form K × (L + M) can be easily resolved as K × (L + M) = KL + KM. This is known as the distributive law of multiplication’s application in addition. Likewise, the distributive law also stands true for expression containing subtraction. This is expressed as K × (L – M) = KL – KM.

As you all can witness, K is being distributed to both the terms in addition or subtraction. Here K is known as an operand, and the terms inside the expression are known as addends.

Let us learn some important terms we have learned so far:

  • Operand: The term being distributed is known as the operand.
  • Addends: The terms inside the bracket which are either added or subtracted are known as addends.
  • Distributive property of addition: K × (L + M) = KL + KM
  • Distributive property of subtraction: K × (L – M) = KL – KM

We can visualize now it states that when the operand is multiplied by the sum or difference to the addends, it is equal to the sum or difference of the individual product of operand and addend terms.

Distributive Property Formula

The formula for a given value’s distributive property can be stated as

c * ( a + b ) = ca + cb

This concludes all the theoretical aspects of the distributive property of multiplication. Next, let us look at the distributive law of multiplication over addition and subtraction in-depth with proper instances.

Distributive Property of Addition

When multiplying a number (operand) by the summation of two integers (addend), we use the distributive property of addition. Multiplying three by the sum of 10 + 8 is a good example. 3 x (10 + 8) is the mathematical expression for this.

Example: The distributive principle of addition may solve the formula 3 x (10 + 8).

Solution: Using this, we multiply each addend by three using the distributive property before solving the formula 3 x (10 + 8). After that, we may add the products by dividing the number 3 between the two addends. This signifies that the addition will take place before the multiplication of 3 (18) and 3 x (10) + 3 x (8) = 30 + 24 = 54 is the result of the distribution property of addition.

Distributive Property of Subtraction

Similarly, when multiplying a number (operand) by the difference between two integers (addend), we use the distributive property of subtraction. Multiplying three by the difference of 10 – 8 is a good example of subtraction’s distributive property. The mathematical expression for this equation is 3 x (10 – 8).

Example: The distributive principle of subtraction may be used to solve the formula 3 x (10 – 8).

Solution: Using this, we multiply each addend by three before solving the formula 3 x (10 – 8). After that, we may subtract the products by dividing the number 3 between the two addends. This signifies that the subtraction will take place before the multiplication of 3 x (18) and 3 x (10) – 3 x (8) = 30 – 24 = 6 is the result of the distributive property of subtraction.

We have talked so much about the distributive property, but how does it stand true in mathematics? Is there a way to verify this property? Indeed there is verification. Continue reading the article to know why.

Verification of Distributive Property

Let’s look at how it works for various operations. We’ll use the distributive law to apply the two basic operations of addition and subtraction separately.

  1. Distributive Property of Addition: We already know that the addition’s distributive property is given as k × (l + m) = kl + lm. Now it is time to verify this property by taking an example.

Example: Let us take an Expression, say, 10 x ( 3 + 6).

Solution: We will normally solve this expression by using the rules of BODMAS as standard.

In the first step, we will always solve the expressions inside the bracket. In this case (3 + 6 ) = 9. In the second step, we will multiply 10 by the number obtained, i.e. 9. This will give us the result as 10 x 9 = 90.

Now solve this using the distributive property of addition:

10 x ( 3 + 6 ) = (10 x 3) + (10 x 6)

= 30 + 60

= 90

As we can see both the methods yield the same result.

  1. Distributive Property of Subtraction: Now, let us verify the same for the distributive property of subtraction. We all already know that the distributive property of addition is given as k × (l – m) = kl – lm. Now it is time to verify this property by taking an example.

Example: Let us take an expression, say, 10 x (6 – 3).

Solution: We will normally solve this expression by using the rules of BODMAS as standard.

In the first step, we will always solve the expressions inside the bracket. In this case ( 6 – 3 ) = 3. In the second step, we will multiply 10 by the number obtained, i.e. 3. This will give us the result as 10 x 3 = 30.

Now solve this using the addition:

10 x ( 6 – 3 ) = (10 x 6) – (10 x 3)

= 60 – 30

= 30

Distributive Property: Definition, Formula, Examples

 

As we can see both the methods yield the same result again.

Hence, we have verified that the property of both addition and subtraction distribution is true.

Distributive Property of Division

The distributive property of division is the same as the distributive law of multiplication, with only the multiplication sign changing to division along with the operation. The larger term is divided into smaller factors (addend), and the divisor acts as the operand. You will understand this better with the example given below.

Example: Using the Distributive Property of Division, solve 36 ÷ 12.

Solution: 36 can be written as 24 + 12

Therefore we can write 36 ÷ 12 = (24 + 12) ÷ 12

Now, let us distribute 12 inside the bracket

⇒ (24 ÷ 12) + (12 ÷ 12)

⇒ 2 + 1

This gives us the answer as 3.

Distributive Property Examples

Example 1: Solve the Expression 2 (11 + 7) using the Distributive Property.

Solution:

Using the distributive property formula,

k × (l + m) = (k × l) + (k × m)

= (2 × 11) + (2 × 7)

= 22 + 14

= 36

Therefore, the value of 2 (11 + 7) = 36

Example 2: Prove that 5 x (3 – 12) has a Negative Result using the Distributive Property of Multiplication.

Solution:

Using the distributive property formula,

k × (l – m) = (k × l) – (k × m)

= (5 × 3) – (5 × 12)

= 15 – 60

= -45

Therefore, the value of 5 x (3 – 12) = – 45, which is a negative integer.

Frequently Asked Question

1. What is distributive property examples?

Distributive property is a rule that states that you can distribute the terms of an expression. It’s used when you have one term that’s being multiplied by another term but you want to distribute the term being multiplied by another number.

For example:

5(x+y) = 5x + 5y

In this case, x and y are multiplied by 5, which means we can distribute the 5 over them. So we would rewrite this as 50x + 50y.

Let’s look at another example:

(6x+2)(x-1) = 6×2 – 2x – 1

2. What property is distributive property?

It is a property that allows you to divide the whole by its parts. It is usually used in mathematics and algebra. For example, if you have the sum of two numbers and want to find the sum of their parts, you would use the distributive property.

3. What is the distributive property of 3?

The distributive property of 3 is a mathematical rule that allows you to distribute one number to each term in a sum.

For example, if you want to add 2+3+4, you can’t just say “add 6” because 2+3=5 and 4+3=7. You need to find a way to split up the 6 among those two terms.

The distributive property of 3 tells us how to do this: we’ll multiply each term by 3 before adding them together. So our answer is 9+12=21.

4. How do you do the distributive method?

The distributive method is a way to solve an equation by multiplying the parentheses on either side of the equality sign. The distributive law states that when multiplying or dividing by a sum or difference of terms, one must multiply or divide each term in the expression by each term in the sum or difference.

For example, if you have:

(a + 4)(a – 2) = 4a^2 – 8a + 8 – 8a

You would distribute the 4 from the first term to each term in the second term:

4a^2 – 8a + 8 – 8a = (4a^2) + (4(-2)) + (8) + (-8) = 16 – 0 + 0 = 16

5. Why do we use the distributive property?

The distributive property turns a multiplication problem into an addition problem. For example, if you have x * y, where x and y are positive numbers and x is greater than 1, then you can rewrite this as (x – 1) * y + x * y.

It is also useful when solving equations with exponents. For example, if you have 5(x+1) = 10(x), then you can rewrite this as 5x + 5 = 10x.

 

Distributive Property

Distributive Property

Distributive Property – The distributive property is also known as the distributive law of multiplication over addition and subtraction. The name itself signifies that the operation includes dividing or distributing something. The distributive law is applicable to addition and subtraction. Let us learn more about the distributive property of multiplication along with some distributive property examples, how to use the distrivutive property on this page.

What is the Distributive Property?

The distributive property states that an expression which is given in form of A (B + C) can be solved as A × (B + C) = AB + AC. This distributive law is also applicable to subtraction and is expressed as, A (B – C) = AB – AC. This means operand A is distributed between the other two operands.

Distributive Property Definition

According to the distributive property definition, the distributive property allows us to take a factor and distribute it to each member (term) of the group of things that have been added or subtracted. Instead of multiplying the factor by the group as a whole, we can distribute it to be multiplied by each member (term) of the group individually.

Distributive Property Formula

The distributive property formula of a given value is expressed as,

Let us discuss the distributive property of multiplication over addition and subtraction in detail with examples.

Distributive Property of Multiplication Over Addition

The distributive property of multiplication over addition is applied when we need to multiply a number by the sum of two numbers. For example, let us multiply 7 by the sum of 20 + 3. Mathematically we can represent this as 7(20 + 3).

Example: Solve the expression 7(20 + 3) using the distributive property of multiplication over addition.

Distributive Property

Solution: When we solve the expression 7(20 + 3) using the distributive property, we first multiply every addend by 7. This is known as distributing the number 7 amongst the two addends and then we can add the products. This means that the multiplication of 7(20) and 7(3) will be performed before the addition. This leads to 7(20) + 7(3) = 140 + 21 = 161.

Distributive Property of Multiplication Over Subtraction

The distributive property of multiplication over subtraction is similar to the distributive property of multiplication over addition except for the operation of addition and subtraction. Let us consider an example of the distributive property of multiplication over subtraction.

Example: Solve the expression 7(20 – 3) using the distributive property of multiplication over subtraction.

Solution: Using the distributive property of multiplication, we can solve the expression as follows: 7 × (20 – 3) = (7 × 20) – (7 × 3) = 140 – 21 = 119

Verification of Distributive Property

Let us try to justify how distributive property works for different operations. We will apply the distributive law individually on the two basic operations, i.e., addition and subtraction.

Distributive Property of Addition: The distributive property of multiplication over addition is expressed as A × (B + C) = AB + AC. Let us verify this property with the help of an example.

Example: Solve the expression 2(1 + 4) using the distributive law of multiplication over addition.

Solution: 2(1 + 4) = (2 × 1) + (2 × 4)

⇒ 2 + 8 = 10

Now, if we try to solve the expression using the law of BODMAS, we will solve it as follows. First, we will add the numbers given in brackets, and then we will multiply this sum with the number given outside the brackets. This means, 2(1 + 4) ⇒ 2 × 5 = 10. Therefore, both the methods result in the same answer.

Distributive Property of Subtraction: The distributive law of multiplication over subtraction is expressed as A × (B – C) = AB – AC. Let us verify this with the help of an example.

Example: Solve the expression 2(4 – 1) using the distributive law of multiplication over subtraction.

Solution: 2(4 – 1) = (2 × 4) – (2 × 1)

⇒ 8 – 2 = 6

Now, if we try to solve the expression using the order of operations, we will solve it as follows. First, we will subtract the numbers given in brackets, and then we will multiply this difference with the number given outside the brackets. This means 2(4 – 1) ⇒ 2 × 3 = 6. Since both the methods result in the same answer, this distributive law of subtraction is verified.

Distributive Property of Division

We can show the division of larger numbers using the distributive property by breaking the larger number into two or more smaller factors. Let us understand this with an example.

Example: Divide 24 ÷ 6 using the distributive property of division.
Solution: We can write 24 as 18 + 6
24 ÷ 6 = (18 + 6) ÷ 6
Now, let us distribute the division operation for each factor (18 and 6) in the bracket.
⇒ (18 ÷ 6) + (6 ÷ 6)
⇒ 3 + 1
Therefore, the answer is 4.
