This lesson is part of the following series:
Combined Beginning Algebra and Geometry Series (30 lessons, $9.90)
Basic Algebra Help 3.5 Hours (14 lessons, $5.94)
This video is about the "M" word. I hate telling students to memorize something but this time....that's the truth. You have to memorize these three rules.
If you want to be successful in Algebra you must learn to add, subtract, multiply, and divide with positive and negative numbers. This video shows you how these rules work and how to use them.
As you watch this video, make sure each step is clear to you. If it is not, pause the lesson, rewind, and watch again. Download the PDF and work right along with me.
In the end you will know these rules "as well as you know your name". That is what it takes to move forward with a good foundation.
The best math help you can find anywhere allows you to work at your own pace, encourages repetition, and talks to you 1:1. That is what this video offers you.

Welcome! I'm so glad you are here! Math help is here for you when you need it.
I believe that using these Algebra and Geometry videos will help you understand the basics of Algebra and Geometry.
Some students try very hard and still struggle to pass math. They start off strong but things quickly begin to fall apart. That happens as soon as the student becomes lost. Teenagers who find themselves in this position often let it "get away from them" before they seek help. Because Math is always a class of stepping stones, it rarely gets better without help.
I urge you to seek help from your child's teacher first. Always. These Algebra and Geometry videos can help too. You can watch...
