Part 1 of Order of Operations: Explains the order of operations, what it means, and shows examples. Basic--no negative numbers or fractions.

• What is the order of operations?
• What are the basic operations?
• How do you know what to do first when simplifying an expression that has more than one operation?
• How do you know what to do first when you evaluate 15 - 2*4?
• How can you simplify 5^2 - 3 + 8 using order of operations?
• Why does 25 - 3 + 8 = 30?
• How would you simplify (15 - 2)*4?
• How would you simplify 5^2 - (3 + 8)?
• How does adding parentheses change a problem?
• How can you evaluate 48/6*4 using order of operations?
• How would you evaluate 48/(6*4)?
• How can you evaluate 4 + 5(10 - 2^3) using order of operations?
• What does 7*3^2 equal using order of operations?
• How do you evaluate 100/10/2 using order of operations?
This lesson is an introduction to order of operations. The order of operations is written out and explained, then many example problems are shown. In some problems, we examine how parentheses would change the result of the problem. This is a wonderful introduction to using order of operations to simplify expressions.
