BCcampus Open Education<\/a> believes that education must be available to everyone. This means supporting the creation of free, open, and accessible educational resources. We are actively committed to increasing the accessibility and usability of the textbooks we produce.<\/p>\n This textbook is an adaptation of an existing textbook that was not published by us. Due to its size and the complexity of the content, we did not have capacity to remediate the content to bring it up to our accessibility standards at the time of publication. This is something we hope to come back to in the future.<\/p>\n In the mean time, we have done our best to be transparent about the existing accessibility barriers and features below:<\/p>\n Known Accessibility Issues and Areas for Improvement<\/p>\n Let Us Know if You are Having Problems Accessing This Book<\/p>\n We are always looking for ways to make our textbooks more accessible. If you have problems accessing this textbook, please contact us to let us know so we can fix the issue.

In this chapter we will work with rational numbers, but you will be also introduced to irrational numbers. The set of rational numbers together with the set of irrational numbers make up the set of real numbers.<\/p>\n In algebra, letters of the alphabet<\/a> are used to represent variables.<\/p>\n Letters often used for variables are .<\/p>\n Variables and Constants<\/strong><\/p>\n To write algebraically, we need some symbols as well as numbers and variables. There are several types of symbols we will be using. There are four basic arithmetic operations<\/a>: addition, subtraction, multiplication, and division. We will summarize them here, along with words we use for the operations and the result.<\/p>\n","protected":false},"excerpt":{"rendered":"Accessibility of This Textbook<\/h3>\n
