What is an agreed set of rules to evaluate numerical expression?

The usual rules are: * Evaluate anything within parentheses first. * Evaluate multiplications and divisions from left to right. * Then evaluate additions and subtractions from left to right.


How would you evaluate a numeric expression with addition subtraction multiplication and exponents?

You didn't include division in your question, but I will include it in the answer. First, evaluate all the exponents. Second, do all the multiplications and divisions together, in order from left to right. Third, do all the additions and subtractions together, in order from left to right.


Is a rule used to clarify which procedures should be performed first in a given mathematical expression?

BIDMAS (UK) or PEMDAS (US). B or P : Brackets (Parentheses) I or E : Index (Exponent) DM or MD : Division and Multiplication. Equal priority, evaluate from left to right. AS : Addition and Subtraction. Equal priority, evaluate from left to right.


How do you use the order of operations to evaluate expressions with exponents?

To evaluate expressions with exponents using the order of operations, follow the PEMDAS/BODMAS rules, which stand for Parentheses/Brackets, Exponents/Orders, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right). First, calculate any expressions inside parentheses or brackets, then evaluate the exponents. After that, perform multiplication and division before finally carrying out addition and subtraction. This systematic approach ensures that each part of the expression is calculated in the correct order.


What is a set of rules for evaluating an expression involving more than one operation?

First evaluate all powers. Then evaluate multiplications and divisions, from left to right. Then evaluate additions and subtractions, also from left to right.Parentheses change the order of operations: you must evaluate anything in parentheses first, before combining it with anything outside the parentheses. Within the parentheses, the first rule also applies (first evaluate powers... etc.).Parentheses can be implied in some cases. For example, in fractions, you have to evaluate the numerator and the denominator separately, before carrying out the division of numerator / denominator. Also, in the case of powers, e.g. 25+3, the exponent has to be evaluated before the power. In the example, you add 5+3 before calculating the power.
