Commutative property of addition is when 3+9=12 and 9+3=12.

## What number sentence shows the commutative property of addition 9 8 17?

An example of formula that shows Commutative Property of Addition is A + B = C = B + A; wherein A and B are the addends and C is the sum. Therefore, the number sentence of 9+8=17 that shows the Commutative Property of Addition is 8+9=17.

## Which number sentence shows the commutative property of multiplication?

6 x 7 = 42 and 7 x 6 = 42. This concludes that 6 x 7 = 7 x 6 = 42 and demonstrates the commutative property of multiplication between the two numbers.

## What is commutative property sentence?

The commutative property says that the sum does not change when the order of the addends is changed. The Commutative Property. Click on the example of the commutative property. 14 × 9 = 9 × 14. 14 + 9 = 17 + 6.

## What is the definition of commutative?

of or relating to commutation, exchange, substitution, or interchange. Mathematics. (of a binary operation) having the property that one term operating on a second is equal to the second operating on the first, as a × b = b × a. having reference to this property: commutative law for multiplication.

## How do you describe associative property?

This property states that when three or more numbers are added (or multiplied), the sum (or the product) is the same regardless of the grouping of the addends (or the multiplicands). Associative property involves 3 or more numbers. …

## How do you describe 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 commutative property and distributive property?

Since multiplication is commutative, you can use the distributive property regardless of the order of the factors. The Distributive Properties. For any real numbers a, b, and c: Multiplication distributes over addition: a(b + c) = ab + ac. Multiplication distributes over subtraction: a(b – c) = ab – ac.

## What is the connection between repeated addition and an array?

Arrays and repeated addition An array is a group of objects arranged in rows and columns. We can use arrays to show repeated addition. Multiplication is repeated addition. We can use arrays to show multiplication as repeated addition.

## What is an example of repeated addition?

Repeated addition may be helpful for children as they go up the school and are still not confident with their times tables. For example: a Year 3 child who does not know their 6x table yet, may find it easier to work out 4 x 6 by writing 6 + 6 + 6 + 6 and then slowly adding up the 4 sixes.

## How do you introduce a repeated addition?

Write a repeated addition expression (3 + 3 + 3 + 3). Ask a student to solve (12 chocolate chips). Remind students that when we are adding the same number repeatedly, then we can use multiplication. Write a multiplication equation (4 x 3 = 12) and say, “4 groups of 3 is 12.”

## What is repeated addition called?

Repeated addition is adding equal groups together. It is also known as multiplication. If the same number is repeated then, we can write that in the form of multiplication.

## Which is the shortest form of repeated addition?

Repeated addition is also known as multiplication. If the same number is repeated then in short we can write that in the form of multiplication. Here 2 is repeated 5 times so in short we can write this addition as 2 x 5.

## Why repeated addition is important?

Repeated addition is the easiest way to progress from additive to multiplicative understanding. It helps kids build rock solid mathematical understandings, compared to solving pages of multiplication problems. If this step is missed students will struggle with multiplication down the line.
