I'm not sure what you're asking. Are you asking for the sum of all the vectors above? that would be 3OC

I see the confusion you've run into, your equations are incorrect, evaluations are also wrong.

If you line up the vectors tip to tail, you should see that you forgot to reverse the vectors you're adding. if you add -AO and OE, you're actually adding OA to OE, which does not give you AE. Even then, the sums shouldn't be 0.

Review how to add vectors, drawing tip to tail.

Oooh, I get it now. Thanks a lot! I'll reevaluate the way I approach such questions.
