Discrete Math  Geometric Vectors

I'm lost!
How do you add the following vectors? Please provide a step by step answer!
1) EA  CB + DB + AD
2) PT  QT + SR  SQ

Since vectors have magnitude and direction, a vector like CB = +BC
so EA  CB + DB + AD
= EA + AD + DB + BC
= EC
notice I made then terminal point of a vector equal to the initial point of the next vector, so you are "just going" from E to A, then onto D, and then to B and finally from B to C.
So you have gone from E to C, or the vector EC
Do the second question the same way
