There are different rules for different operations.

Parenthesis Exponents Multiply Divide Addition Subration Or, PEMDAS

Signed numbers are "plus" and "minus" numbers.

additive inverse and associative property and if one is involved, then also identity

The set of real numbers is closed under addition, subtraction, multiplication, and division (except that you cannot divide by zero). By closed, this means that if the two numbers in the operation are both real numbers, the result of the operation will always be a real number. Dividing by zero is undefined (for all practical purposes)

No, they are binary operators. Two numbers (or variables) are combined, according rules of operation to give a single answer.

These mnemonic devices were developed by SHERWIN E. BALBUENA, mathematics teacher of Cabitan NHS, Mandaon, Masbate, Philippines", to teach his students with disabilities the rules in operating signed numbers. LA US means "Like signs Add, Unlike signs Subtract". This device lets the student remember the rule in adding signed numbers. LP UN means "Like signs Positive, Unlike signs Negative". This device lets the student recall the rules in finding the product and quotient of two signed numbers.

Most operations may be carried out on signed numbers: addition, subtraction, multiplication, division, exponentiation, trigonometric functions and so on. For some operation the domain may need to be restricted (or the codomain extended).
