Exploring Order of Operations with Integers

This video tutorial explains the order of operations, often remembered by the acronym PEMDAS (Parentheses, Exponents, Multiplication, Division, Addition, Subtraction). It emphasizes that multiplication and division, as well as addition and subtraction, should be performed from left to right, depending on which comes first. Two example problems are solved to illustrate these rules: one without parentheses and one with parentheses, highlighting the importance of following the correct order to achieve the right answer.

What does the mnemonic 'Please Excuse My Dear Aunt Sally' stand for?

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

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

When performing operations, which should you do first if both multiplication and division are present?

• Always multiplication

• Always division

• Whichever comes first from the left

• Whichever comes first from the right
