Students will review:
This chapter helps students review the lessons in a basic arithmetic calculations unit of a standard GMAT prep course. Topics covered include:
- Accomplishing arithmetic calculations with whole numbers
- Learning about the different types of numbers
- Calculating problems with signed numbers
- Finding the greatest common factor
1. What are the Different Types of Numbers?
Learn all of the different types of numbers: natural numbers, whole numbers, integers, rational numbers, irrational numbers, and real numbers. This video lesson teaches you how to classify any numbers you come across.
2. Arithmetic with Whole Numbers
There are four basic mathematical operations: addition, subtraction, multiplication, and division. These four operations are used in a wide range of everyday skills and are the fundamental blocks of arithmetic.
3. Arithmetic Calculations with Signed Numbers
Signed numbers are often referred to as integers. Integers include both positive and negative numbers. In this lesson, you will learn how to add, subtract, multiply, and divide integers.
4. What Is The Order of Operations in Math? - Definition & Examples
The order of operations is the steps used to simplify any mathematical expression. In this video, learn how to solve problems using these steps and easy tricks to remember them.
5. Order Of Operations: Definition, Problems & Examples
In this lesson, we'll discuss order of operations. We'll look at what the order is, how some people remember it, and one of the most common misconceptions people have regarding it.
6. How to Find the Prime Factorization of a Number
The prime factorization of a number involves breaking that number down to its smallest parts. This lesson will show you two different ways to discover the prime factorization of any number.
7. How to Find the Greatest Common Factor
If the factors of a number are the different numbers that you can multiply together to get that original number, then the greatest common factor of two numbers is just the biggest one that both have in common. See some examples of what I'm talking about here!
8. How to Find the Least Common Multiple
The least common multiple of two numbers is the smallest number that can be divided evenly by your two original numbers. See some examples of what I'm talking about here!
9. Commutative Property: Definition & Review
In this lesson, you're going to learn the meaning of the commutative property as well as in which mathematical operations it is applicable and in which ones it is not.
