# Ch 6: NES Essential Academic Skills Math: Computing Integers

### About This Chapter

## NES Essential Academic Skills Math: Computing Integers - Chapter Summary

These video lessons are designed to expand your ability to compute integers. Before you sit for the NES Essential Academic Skills Mathematics examination, take the time to refresh your memory of the different kinds of integers. You may also review the rules for performing operations with integers in this chapter. After studying the lessons, you could have a better idea of how to:

- Compare and provide examples of integers
- Add positive and negative integers
- Solve addition equations with one- and two-digit integers
- Find the sum of three or more integers
- Calculate subtraction equations with one- or two-digit integers
- Outline the steps necessary to multiply and divide integers
- Simplify expressions with integers

Develop your expertise in these and other areas as you seek teaching certification. The animated video lessons aim to be clear and concise. They're generally less than ten minutes long, and they can be accessed online anytime. You should also take each of the short self-assessment quizzes, which will test your readiness for pertinent questions on the NES Essential Academic Skills Mathematics examination.

### NES Essential Academic Skills Math: Computing Integers Chapter Objectives

The NES Essential Academic Skills examination includes three subtests in Reading, Writing and Mathematics. Prove your comprehension of integers and the techniques used to compute them during the NES Essential Academic Skills Subtest III - Mathematics examination. This subtest is computer based, and it contains 45 multiple-choice questions. You'll have one hour to provide complete answers on the third subtest and potentially earn a mathematics endorsement.

### 1. What are Integers? - Definition & Examples

Integers are numbers that have no fractional or decimal components. Learn the definitions of integers and non-integers and how to differentiate between them, plus find examples of numbers that contain both.

### 2. How to Compare Integers

Discover how to compare integers, which are all positive and negative whole numbers. Review what integers are before exploring the meanings and characteristics of less than, greater than, and equal to.

### 3. Adding Positive & Negative Integers

Positive integers are whole numbers larger than zero, and negative integers are whole numbers smaller than zero marked with the '-' sign (-1, -2, -3, etc). Learn methods of how to add positive and negative integers through examples provided.

### 4. Addition Equations with One-Digit Integers

Equations with single-digit integers include a variable 'X,' and an integer that can be solved using clever addition and subtraction. Discover the steps to learn how to solve these equations through example problems.

### 5. Addition Equations with Two-Digit Integers

Addition equations can include numbers higher than 10, which all contain two-digits. Follow the steps of how to solve addition equations with these integers, and see examples of how to solve for X to arrive at the solution.

### 6. Adding Three or More Integers

Integers are whole numbers which can be positive or negative. Study the definition of integers, learn about adding three or more integers, and study examples of how this works.

### 7. Subtraction Equations with One-Digit Integers

Subtraction equations with a one-digit integer can be easy, and even fun, to solve once they are understood. Discover what a subtraction equation is and how to solve one, then view a couple examples to clarify the process.

### 8. Subtraction Equations with Two-Digit Integers

Subtraction equations are problems that contain a subtraction operation. Learn how to solve subtraction equations with two-digit integers, and study the examples of this type of equation.

### 9. Multiplying Integers: Rules & Examples

In multiplying integers, the sign of the product varies based on the signs of the given integers. Learn about the rules and examples of multiplication of integers, and learn how to multiply simple, complex, and negative integers.

### 10. Dividing Integers: Rules & Terminology

In dividing integers, it is important to consider the sign of the numbers. Explore the rules and terminology on division of integers, and learn how to divide numbers with the same sign, with different signs, or with zero as a numerator or denominator.

### 11. How to Simplify Expressions with Integers

Expressions with integers are easy to simplify once the basics are understood. Delve into this topic and explore what an integer expression is and how to use order of operations, then view a couple of examples.
