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.
