# A.1 Foundations of Algebra

http://www.freemathvideos.com In this video series explain the properties of real numbers. When working with numbers in mathematics it is very important to understand the properties of real numbers because knowing the properties tells us what we are allowed to do with certain numbers and why. When mathematics gets more difficult these properties remain true and become a foundation of how to solve and simplify in mathematics.

http://www.freemathvideos.com Definitions are very important to your understanding of why and how we use mathematical processes. Without understanding what a process or certain terms mean it is very hard to understand how or why to do something. That is why I want to spend some time explaining to you these processes or definitions. Please understand that these videos are my interpretation and that there may be other ways of explaining or describing the same information.

### A.143 Simplifying with negative one

http://www.freemathvideos.com In this video series I will show you how to apply the distributive property when a grouping term is being multiplied by a negative one. We often omit the one when writing and applying the distributive property of negative one because it does not change the absolute value of the number. However we still need to multiply the negative one to every term inside the grouping term. Tags: negative, negative one, distributive property, simplify, grouping term, how to, learn, expression
