Understanding Function Operations and Parentheses

This video tutorial covers operations with functions, including addition, subtraction, multiplication, and division. The instructor demonstrates how to evaluate these operations at specific numbers, such as F plus G of 2, F minus G of -1, F times G of 3, and F over G of 4. The video emphasizes the importance of using parentheses in subtraction to avoid errors. The tutorial concludes with a mention of a future video focusing on operations with functions using variables instead of specific numbers.
