Answer:
Example 2: List the elements of the set {x | x is a natural number between 5 and 11}.
There are two parts to this:
the number has to belong to the set of natural numbers {1, 2, 3, ...} and
it has to be between 5 and 11 - which by the way would not include those two numbers.
Let's see what we get when we put those ideas together:
{6, 7, 8, 9, 10}
You would not have an ellipsis after the 10 because this set would stop at the number 10.
Step-by-step explanation:
Have you ever sat in a math class, and you swear the teacher is speaking some foreign language? Well, algebra does have it's own lingo. This tutorial will go over some key definitions and phrases used when specifically working with sets of numbers as well as absolute values and opposites. Even though it may not be the exciting part of math, it is very important that you understand the language spoken in algebra class. It will definitely help you do the math that comes later. Of course, numbers are very important in math. This tutorial helps you to build an understanding of what the different sets of numbers are. You will also learn what set(s) of numbers specific numbers, like -3, 0, 100, and even pi (pi) belong to. Some of them belong to more than one set. I think you are ready to go forward. Let's make you a numeric set whiz kid (or adult).
