# Ch 8: NES Math: Vector Operations

### About This Chapter

## NES Math: Vector Operations - Chapter Summary

Use the lessons in this chapter to review facts about operations and calculations with vectors as you study for the NES Math exam. Our lively videos, self-assessment quizzes and useful study aids will guide you in preparing for questions on:

- Types of vectors
- Geometric approach to vector addition and subtraction
- Resultants of vectors
- Scalar multiplication of vectors

You can watch these videos and take the accompanying quizzes anytime your schedule allows, using a computer or mobile device. Our instructors keep the lessons brief and use plenty of animations, examples and practice problems to explain their topics. If you have questions, you can easily contact them through our message board.

### NES Math: Vector Operations - Chapter Objectives

Arizona, New Mexico, Oregon, Washington and Wisconsin use the NES Math test as one way of assessing readiness for certification to teach the subject at the secondary level. The test is computer-delivered and consists entirely of multiple-choice questions, divided into five content domains. Questions on vector operations are in the content domain on Statistics, Probability, and Discrete Mathematics, which accounts for 19% of the test's total score.

The lesson quizzes and the chapter exam we offer are in the same format as the NES Math test, so taking them will help you become familiar with the types of questions you'll face. Our tests also show you where you may need additional study prior to test day, and video links can point you to the right spots in the lesson for review.

### 1. What Is a Vector? - Definition & Types

After watching this lesson, you will be able to explain what vectors are in physics, give some examples of vectors and have a basic idea of how they can be manipulated mathematically. A short quiz will follow.

### 2. Vector Addition (Geometric Approach): Explanation & Examples

After watching this video, you will be able to explain why we might need to add two vectors and, given magnitudes and directions, add two vectors using geometric methods. A short quiz will follow.

### 3. Vector Subtraction (Geometric): Formula & Examples

After watching this lesson, you will be able to subtract vectors geometrically and give examples of how that process might be used in physics. A short quiz will follow.

### 4. Resultants of Vectors: Definition & Calculation

After watching this video, you will be able to explain what a resultant of a vector is and use mathematics to calculate the resultant of two vectors. A short quiz will follow.

### 5. Scalar Multiplication of Vectors: Definition & Calculations

After watching this video, you will be able to explain what scalar multiplication is and complete basic calculations involving the scalar multiplication of vectors. A short quiz will follow.
