PEMDAS: What Does It Mean?
PEMDAS helps us know what to do first when a math problem has more than one operation.
Letter What It Means What You Do
P Parentheses Do what is inside ( ) first
E Exponents Solve powers like 2²
M Multiplication Multiply
D Division Divide
A Addition Add
S Subtraction Subtract
Important Rule
Multiplication and division are done from left to right.
Addition and subtraction are also done from left to right.
You do NOT always do multi...
This resource explores the topic of order of operations in mathematics, specifically focusing on the rules encapsulated in the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction). It opens with a problem revealing how different approaches can lead to different answers, thereby emphasizing the importance of a standardized method for solving mathematical expressions. The document details the order of operations step-by-step, providing worked examples of calculations using parentheses, multiplication, division, and exponents. It also includes real-world applications involving simple scenarios, such as calculating the total number of marbles and the number of pencils remaining after lending. Additionally, there are opportunities for group activities, critical thinking challenges, and an exit ticket to reinforce learning before the lesson concludes.
