Order of Operations and Basic Arithmetic

The video tutorial explains how to simplify expressions using the order of operations. It demonstrates this with two examples: simplifying negative four plus seven squared and negative two plus six cubed. The process involves calculating the sum inside the parentheses first, then applying the power to the result. The first example results in positive nine, while the second example results in positive sixty-four.
