The subtraction of vectors is accomplished in the same way as the addition of vectors:
Definition
Let a, b, and c be vectors of the same order and form. The difference vector c := a - b is then calculated by subtracting the corresponding elements of the vectors a and b: c_{k }:= a_{k }- b_{k}.Note that the subtraction can be formally seen as a summation: a-b:=a+(-b).
Subtracting two equal vector results in a vector with all elements being
zero. This vector is also called a zero vector, usually depicted by o.
