Whenever evaluating expressions that do not have parentheses (brackets) nor indices.

Multiply out all the brackets (parentheses) and then combine like terms.

Yes. The default order of evaluating expressions is BODMAS/PEMDAS. To change that order, parts of the expression need to be put in brackets (parentheses). Yes.

The default order of evaluating expressions is BODMAS/PEMDAS. To change that order, parts of the expression need to be put in brackets (parentheses).

The standard order of operations follows the acronym PEMDAS. This is Parentheses, Exponents, Multiplication, Division, Addition, Subtraction. So operations are done on expressions within parentheses first.

Put a comma between them. Better still, put them in brackets (parentheses) before that.

The process of multiplying a number outside a set of parentheses to everything inside the parentheses is called distributing or the distributive property. This property is used to simplify algebraic expressions by multiplying the external number to each term inside the parentheses.

* 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

Do you mean like this: (x + 5)(2x + 7) If so, then it means you multiply.

Adding parentheses in an equation can change the order of operations and is known as the distributive property. This property allows you to group terms together for simplifying expressions or equations.
