Vector Operations and Scalar Functions

The video tutorial covers three basic vector operations: scalar multiplication, addition, and subtraction. It explains how scalar operations involve multiplying a vector by a number, while addition and subtraction involve two vectors. The tutorial discusses the resulting vectors' meanings, such as scaling, averaging, and direction change. It emphasizes the importance of the order of operations, especially in subtraction, and demonstrates how to use Grasshopper components for these operations.
