{...} - {...} -- sum of two vectors

{...} - {...} -- sum of two vectors

Synopsis:

Usage: x = v-w

Operator: - -- a unary or binary operator, usually used for negation or subtraction

Input:

v, an instance of class List: a list interpreted as a vector

w, an instance of class List: a list interpreted as a vector

Output:

x, an instance of class List: the difference of the two vectors

Code:
