The order of operations is PEMDAS: Parenthesis, Exponents, Multiplication, Division, Addition, Subtraction. The phrase "Please Excuse My Dear Aunt Sally" is often used to help remember the order.

What role does Order of Operations play in simplifying algebraic expressions What would happen if we didn't use order of operations?

The order of operations defines, in the absence of parentheses, the order in which binary operations in arithmetic (or algebra) may be carried out. If it were not used, most expressions with more than one kind of operation would have more than one answers. Alternatively, each expression would have to have a parentheses to indicate the Order of Operations and that would make expressions more difficult to read. eg 2+3*5 = 2+15 = 17 (following Order of Ops), but 2+3*5 = 5*5 = 25 (NOT following Order of Ops).


What is a difficult order of operations problem?

Many expressions involve two or more operations. When simplifying such expressions, it is important to perform the operations in the following order:1. Perform any operation(s) within group symbols, which are:a. parentheses ( )b. brackets [ ]c. braces { }d. fraction bar /e. absolute-values bar | |f. radical sign2. Simplify all powers.3. Multiply and divide in order from left to right.4. Add and subtract in order from left to right.If you don't follow this order of operations, you will find a wrong answer.


According to the order of operations for formulas the first expressions calculated are those within?

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.


What is the rules for evaluating expressions?

The various operations within the expression are carried out using the order of operations: BIDMAS (UK) or PEMDAS (US).


Where does pemdas come from?

PEMDAS is an acronym to help you remember the order of operations in mathematical equations.First, you do expressions within Parenthesis and/or Exponents.Then, you do expressions involving Multiplication and/or Division.Finally, you do the expressions involving Addition and/or Subtraction.

What property is it called if you add parentheses?

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.
