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

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

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.

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.

* 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.
