You need to memorize some rules. For instance, multiplication and division have a greater priority than addition and subtraction; parentheses are used to change the priority.
-----------------------------------
Students often learn this mnemonic: "Please Excuse My Dear Aunt Sally" .
Do the operations in this order:
1st, simplify what's in Parentheses. This includes fraction bars, absolute value signs and radical signs.
2nd, evaluate powers ("Exponents") .
3rd, do all Multiplications and Divisions in order from left to right.
4th, do all Additions and Subtractions in order from left to right.
Once you get used to applying "Aunt Sally's Rule", you'll find it's pretty hard to beat!
What else can I help you with?
Why is it important to use order of operations to evaluate algebraic expressions?
I think it is important because you need to know it when you get older.
How do you evaluate a math expression?
The evaluate a algebraic math expression you first must substitute a number for each variable. Then you must perform the operation in the correct order.
Do you have to arrange in order the terms in algebraic expressions before adding?
Yes
How is order of operations used when evaluating algebraic expression?
The order of operations is a set of rules that dictates the sequence in which mathematical operations should be performed to accurately evaluate algebraic expressions. This sequence is often remembered by the acronym PEMDAS: Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right). By following this order, you ensure that complex expressions are simplified correctly, leading to consistent and accurate results. Neglecting this order can result in incorrect answers.
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 the process for evaluating expressions called?
An algebraic expression is a process for evaluating expressions. Replacing variables with numerals and following a standard order of operations is used for the process.
What is the order of operation performed in a fraction?
To Evaluate expressions using the order of operations where there are fraction bars, simplify the top and bottom first, then divide.
