How do you add the following vectors? Please provide a step by step answer!

1) EA - CB + DB + AD

2) PT - QT + SR - SQ

**Reiny**, Thursday, February 7, 2008 at 11:18pmSince 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
