Order of Operations
A rule that tells the correct sequence of steps for evaluating a math expression.
The order of operations is a rule that tells the correct sequence of steps for evaluating a math expression. We can remember the order using PEMDAS: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).
This framework ensures that everyone gets the same answer when evaluating an expression.
- Type: Mathematical Framework
- Core Idea: Consistent Evaluation of Expressions
- Key Elements: PEMDAS/BODMAS
PEMDAS
The steps for the order of operations.
Parentheses
First, evaluate any expressions inside parentheses or other grouping symbols.
Exponents
Next, evaluate any exponents.
Multiplication and Division
Then, perform any multiplication or division, working from left to right.
Addition and Subtraction
Finally, perform any addition or subtraction, working from left to right.
Implementation & Strategy
Costs, timelines, and strategic considerations for adopting the Order of Operations.
Estimated Project Costs
The Order of Operations is a mathematical rule, so it doesn't have a direct cost. However, there are costs associated with teaching and learning the rule. These costs can range from a few dollars for a textbook to several thousand dollars for a private tutor.
Implementation Strategy
The Order of Operations is a fundamental concept in mathematics, and it is typically taught in elementary school. The best way to learn the Order of Operations is to practice, practice, practice.
