Why does commutative and associative properties can help us add mixed numbers?
The commutative and associative properties are helpful when adding mixed numbers because they allow for flexibility in rearranging and grouping the numbers. The commutative property lets us change the order of the mixed numbers being added without affecting the sum, while the associative property lets us group different parts of the numbers together for easier calculation. This can simplify the addition process, particularly when dealing with fractions and whole numbers in mixed numbers. By using these properties, we can efficiently find a sum without getting confused by the complexity of the numbers.
What is associative property of addition with fractions?
The associative property of addition states that when adding three or more numbers, the way in which the numbers are grouped does not affect the sum. For fractions, this means that for any fractions a, b, and c, the equation (a + b) + c = a + (b + c) holds true. This property allows for flexibility in calculation, making it easier to simplify or compute sums involving fractions.
How can you use the distributive property to simplify?
To simplify using the distributive property, you distribute a number or variable outside a set of parentheses to each term inside the parentheses. For example, if you have the expression 3(x + 2), you would distribute the 3 to both x and 2 to get 3x + 6. This helps you combine like terms and simplify the expression further.
Simplify the expression 9(x plus 3) using the Distributive property.?
To simplify the expression (9(x + 3)) using the Distributive property, multiply 9 by each term inside the parentheses. This gives you (9 \cdot x + 9 \cdot 3), which simplifies to (9x + 27). Thus, the simplified expression is (9x + 27).
How can you use properties of operation to write an equivalent expression?
You can use properties of operations, such as the commutative, associative, and distributive properties, to write equivalent expressions. For example, the commutative property allows you to change the order of terms in addition or multiplication (e.g., (a + b = b + a)). The associative property lets you regroup terms (e.g., ( (a + b) + c = a + (b + c) )). The distributive property allows you to distribute a factor across terms in parentheses (e.g., (a(b + c) = ab + ac)). Using these properties can simplify expressions or rewrite them in different forms while maintaining equality.

What are the directions when you have an expression?
When you have an expression you have to simplify by eliminating all grouping symbols and combining like terms.
Rewriting what expression so that it has no grouping symbols and all of the like terms have been combined?

What property is this (4x8)x3 (8x4)x3?
It is the commutative property of multiplication.
Simplify law of addition?
The Associative Law of Addition says that changing the grouping of numbers that are added together does not change their sum. This law is sometimes called the Grouping Property. Examples: x + (y + z) = (x + y) + z. Here is an example using numbers where x = 5, y = 1, and z = 7.

Do you simplify while using the distributive property to write an expression?
When using the distributive property to write an expression, you do not simplify within the parentheses before applying the property. The distributive property involves multiplying the term outside the parentheses by each term inside the parentheses. Once you have distributed the term, you can then simplify the resulting expression by combining like terms. Simplifying before distributing would result in an incorrect application of the distributive property.
