Order of Operations and Simplification

The video tutorial explains how to evaluate a mathematical expression using the order of operations. It covers multiplication and division with fractions, simplifying fractions, and using reciprocals for division. The tutorial concludes with the final calculation, resulting in a simplified expression of negative eight.

What is the correct order of operations when evaluating an expression?

• Multiply and divide first, then add and subtract

• Add and subtract first, then multiply and divide

• Evaluate expressions inside parentheses last

• Perform operations from right to left
