Is there an association law for vector subtraction?
The representation of vector 1. Algebraic representation: generally, small letters α, β, γ in boldface are used for printing Or a, B, C Handwriting is used in a, B, C, etc Geometric representation: vector can be represented by directed line segment. The length of directed line segment indicates the size of vector
