Algebra


Hello!      Welcome to Algebra I.

I am your math teacher here at CompuHigh. My name is Nicole.  We are going to use a number of math symbols in this class and I will define them here so that you will know what they are. They are very standard on any keyboard, so you have them.

        + Addition Sign
      - Subtraction/Negative Sign
      * Multiplication Sign
      / Division Sign and Fraction Bar
      = Equal Sign
      < Less Than Sign
      > Greater Than Sign
      <= Less Than or Equal To Sign
      >= Greater Than or Equal To Sign
      <> Not Equal To Sign
      ^ Carrot - this symbol raises a number to a power. It is right above your number six key.
      SQRT( )Square root of a number and the number will be inside the parentheses.


Specifically in the lessons on multiplying and dividing fractions, a fraction bar is denoted by a slash / while division is denoted by the symbol ÷. Please do not confuse the fraction bar in these cases for a division sign, division will be denoted by the symbol ÷ only in these cases.

    Revisions are a key part of understanding mathematics.  It is a required part of this course for work to be shown on ALL revisions.

    I will request to see your work if you do not show it- Click here to see how to show your work. I will not give you credit for a lesson that requires revisions if work or explanation is not given. In addition, there is a general rule that if a student gets 3 or less problems incorrect on the first submission, then the student may move on to the next lesson. This is only valid FOR THE FIRST SUBMISSION. Once revisions are required, I will ask for work to be shown for whatever problems I deem necessary to prove mastery of the concepts presented.

    If you need help, ask for help. Be specific with your questions and what you don't understand--I know you may not have done some of this before, but I can only help if you can tell me about the things that confuse you. So if you have any questions, don't hesitate to contact me using the form at the bottom of the page. That's why I'm here. So jump right on in.
