Look It Up!!!



What is math vocabulary? Math vocabulary is easier than any other vocabulary because you must provide examples of what the answer can be or a counter example of what the answer can’t be. Providing these examples is easy as well because there is always going to be a definite answer. For math vocabulary there will always be examples. There will be examples because they are used to explain and to prove or disprove theories. As you expand your math vocabulary you will find that most definitions are rules that can or can’t be broken unless there are exceptions. In the following terms you will see examples and definitions that explain what I mean.

Definitions

Domain: what the variable can equal, all real numbers EXCEPT ZERO.


Factor Tree: a method used to factor radicals in a tree form.


Principal Root: positive square root of a number.


Radical: principal nth root of the number


Radicand: the number underneath the radical sign


Rational Expression: a rational expression is a polynomial fraction that contains variables and anything you do with regular fractions you can do with rational. But there are exceptions.



Directions: Match the examples with the correct vocabulary word!!


1. Radical a. 2b²a³/a

2. Rational Expression b. √16x

3. Principal Root c. All Real Numbers, X ≠ O

4. Factor Tree d.√64←

5. Radicand e. √8
√2 √4
2 2 2

6. Domain f.√81=√9x9=9


As you can see vocabulary is very important. If you don’t know vocabulary how were you supposed to solve the problems? Vocabulary is very important because it allows you to understand examples and answers. In addition to that understanding vocabulary helps you prove and disprove theories. When you apply vocabulary it gives you a better understanding of the topic!!!! Hope
