Mastering the Order of Operations with PEMDAS

This video tutorial covers the order of operations, commonly remembered by the acronym PEMDAS. The instructor explains the hierarchy of operations: parentheses, exponents, multiplication and division (from left to right), and addition and subtraction (from left to right). The tutorial includes five examples demonstrating how to apply these rules, including handling fractions and nested parentheses. The video also promotes an Algebra 1 course with additional lessons.

What does the acronym PEMDAS stand for?

• Parentheses, Exponents, Multiplication, Division, Addition, Subtraction

• Parentheses, Exponents, Multiplication, Division, Addition, Subtraction

• Parentheses, Exponents, Multiplication, Division, Addition, Subtraction

• Parentheses, Exponents, Multiplication, Division, Addition, Subtraction

Which operation should be performed first according to PEMDAS?

• Exponents

• Parentheses

• Addition

• Multiplication

If you have multiple multiplication and division operations, how should you proceed?

• Multiplication first, then division

• From left to right

• Division first, then multiplication

• From right to left
