what is addition of two vector

Two or more vectors may be added to produce their addition. Note that while adding vectors together we need to take into consideration both their direction and magnitude. For example: If two vectors each of magnitude 2 and in the same direction are added we get a vector of magnitude 4 in the same direction. And if two vectors again each of magnitude 2 but in the opposite directions then the resultant is a zero vector. There are different methods to add vectors some of which are listed below: 1. Polynomial method 2. Parallelogram method 3. Method of components
