Basic Arithmetic and Exponents

The video tutorial explains how to solve mathematical problems using the correct order of operations, often remembered by the acronym PEMDAS (Parentheses, Exponents, Multiplication, Division, Addition, Subtraction). It provides three example problems, demonstrating how to apply these operations step-by-step, including handling exponents and performing calculations within parentheses. The tutorial emphasizes the importance of following the correct sequence to achieve accurate results.

What does the 'P' in PEMDAS stand for?

• Product

• Parentheses

• Power

• Proportion
