Basic steps for adding vectors:
- draw first vector
- starting from the head of the first vector, draw the second vector
- repeat for as many vectors as you need
- the resultant will be a vector drawn from the tail of the first vector you drew (start) to the head of the last one (finish).

To subtract vectors:
- make the vector being subtracted negative by flipping it 180 degrees (or just erase the head and draw it where the tail originally was)
- now add the vectors using the same process as addition.
