4(x+y)
To expand the expression 7x(7y) using the distributive property, you distribute the 7x to both terms inside the parentheses. This results in 7x * 7y = 49xy. The distributive property allows you to multiply each term inside the parentheses by the term outside the parentheses, simplifying the expression.
A sentence using the order of operations in mathematics, known as PEMDAS (Parentheses, Exponents, Multiplication and Division from left to right, Addition and Subtraction from left to right), could be: "To solve the expression 3 + 4 x (5 - 2), we must apply the rules of PEMDAS by first simplifying the expression inside the parentheses, then performing the multiplication before finally adding the remaining numbers."
(8x8)=64
Personally, I think no because i think usually we put brackets to simbolise that we are doing more than one equation and has parentheses. :) Play runescape!
The order of operations is a rule that tells the correct sequence of steps for evaluating a math expression. We can remember the order using PEMDAS: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).
NoRestate the question: When using the order of operations to evaluate an expression would you always do multiplication before division?If this is not your question, please clarify and ask the question again. :-)No. Unless parentheses or other grouping symbols indicate otherwise, you do multiplication and division in order from left to right.

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.
* arithmetic expressions are evaluated from left to right using the rules of precedence.. * when parentheses are used,the expressions within parentheses assume highest priority... * if parentheses are nested, the evaluation begins with the inner most parentheses... * the associativity rules are applied when 2 or more operators of same precedence level appear in a sub expression
To idenify and write number sentence that moded numbers stories by using parentheses when more than one operation in involved.
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.
You need to indicate the order in which the operations are to be performed, using parentheses. So for example, you might have a problem (3+2) x 10 which then simplifies to 5 x 10 = 50. That is a product. However, you could also re-organize that as 3 + (2x10) which simplified to 3 + 20 = 23. That is a sum.
