Adding, subtracting, multiplying and dividing two functions

The video tutorial covers the four basic operations on functions: addition, subtraction, multiplication, and division. It emphasizes the importance of understanding notation and using parentheses. The tutorial also explains how to identify domain restrictions, particularly when dealing with division. The box method is recommended for organizing multiplication of polynomials. Factoring is highlighted as a useful technique for simplifying expressions and determining domain restrictions.
