ORELA Math: Vector Operations - Videos & Lessons

About This Chapter

Oregon now uses the National Evaluation Series (NES) examination for teacher certification rather than the ORELA Math examination. Watch this chapter's video lessons to learn about the use of vectors in preparation for this test.

ORELA Math: Vector Operations - Chapter Summary

This chapter's educational video lessons are designed to teach you what you need to know about vector operations in preparation for answering related questions on the ORELA Math examination. Review strategies for adding and subtracting vectors, and learn to take the geometric approach to working with vectors. The information you explore in this chapter could help you with:

Defining vectors and providing examples
Explaining how to geometrically add and subtract vectors
Performing scalar multiplication
Discussing techniques for calculating and using a resultant vector

The lesson instructors are experienced educators who will help you to absorb and review this material on vectors. Take advantage of the opportunities to ask your questions, refer to the included text transcripts and to study at your own pace. You may also use the video tags to watch just a portion of the video again. When you've watched the lessons, take the quizzes that follow and see how much of the information you've remembered.
