How to add two vectors of the same direction? Two vectors of opposite directions?

Two identically directed vectors: the total vector will be directed in the same direction, and its modulus will be equal to the sum of the added vectors.

Two oppositely directed vectors: the total vector will be directed towards the vector with a large modulus, and the modulus of the total vector will be equal to the difference between the vectors (the smaller vector must be subtracted from the larger vector).
