How do you know when to add or subtract using distributive property?

1 Expert Answer a(b+c) = ab + ac is the distributive property. The sign within the parenhteses tells you whether to add or subtract.

What is the rule for using distributive property?

To “distribute” means to divide something or give a share or part of something. According to the distributive property, multiplying the sum of two or more addends by a number will give the same result as multiplying each addend individually by the number and then adding the products together.

What is the distributive property in math addition?

The distributive property is a property of multiplication used in addition and subtraction. This property states that two or more terms in addition or subtraction with a number are equal to the addition or subtraction of the product of each of the terms with that number.

Which of the following is distributive property of multiplication over subtraction?

The correct answer is 30(2) + 30(4). The distributive property of multiplication over subtraction is like the distributive property of multiplication over addition. You can subtract the numbers and then multiply, or you can multiply and then subtract as shown below. This is called “distributing the multiplier.”

What is the distributive property of multiplication over subtraction?

The property states that the product of a number and the difference of two other numbers is equal to the difference of the products.

What is the distributive property of subtraction?

The property states that the product of a number and the difference of two other numbers is equal to the difference of the products.

What's the distributive property of multiplication over addition?

The distributive property of multiplication over addition is applied when you multiply a value by a sum. For example, you want to multiply 5 by the sum of 10 + 3. As we have like terms, we usually first add the numbers and then multiply by 5. But, according to the property, you can first multiply every addend by 5.

Which of the following is distributive property of multiplication over addition?

The distributive property of multiplication over addition is applied when you multiply a value by a sum. For example, you want to multiply 5 by the sum of 10 + 3. As we have like terms, we usually first add the numbers and then multiply by 5. But, according to the property, you can first multiply every addend by 5.

What is distributive property give example?

It is used to solve expressions easily by distributing a number to the numbers given in brackets. For example, if we apply the distributive property of multiplication to solve the expression: 4(2 + 4), we would solve it in the following way: 4(2 + 4) = (4 × 2) + (4 × 4) = 8 + 16 = 24.

What is distributive property in maths for Class 8?

The distributive property of multiplication lets you simplify expressions wherein you multiply a number by a sum or difference. According to this property, the product of a sum or difference of a number is equal to the sum or difference of the products.

What is the formula for distributive property?

• The distributive property is expressed in math terms as the following equation: a(b + c) = ab + ac.

When to use the distributive property?

• The distributive property law can also be used when multiplying or dividing polynomials, which are algebraic expressions that include real numbers and variables, and monomials, which are algebraic expressions consisting of one term.

How can I use the distributive property?

• The distributive property also can be used to simplify algebraic equations by eliminating the parenthetical portion of the equation. Take for instance the equation a(b + c), which also can be written as (ab) + (ac) because the distributive property dictates that a, which is outside the parenthetical, must be multiplied by both b and c.

How do you divide using the distributive property?

• The distributive property states that dividing a sum by a number is the same as dividing each addend by the number and then adding the quotients. *Breaking apart the dividend into easier numbers to divide. Sometimes, it is as easy as breaking the number into expanded form.
