Dear Girls and Boys,
We are moving onward to a new STANDARD- EXPRESSIONS and EQUATIONS. This will mean that when you look into Infinite Campus, you will need to change tabs to Expressions and Equations to see your grades.
Expressions are really Algebraic Expressions- see, you already sound smarter!!! Lol
Algebraic expressions are is an expression that contains a variable. A VARIABLE is a symbol that stands for a number. An algebraic expression has a variable and at least 1 operation(+ - x /).
In algebra, often times, the multiplication signs are omitted. For instance: 6d is 6 times d; 9st is 9 times s times t;mn is m times n; and a ^2 is a times a. The other important vocabulary terms are : COEFFICIENT: a coefficient is a number that is attached to a variable :6x - 6 is the coefficient , and CONSTANTS: these are numbers that stand alone: 6x + 3- 3 is the constant.
To summarize: an equation has a variable and at least one operation.
Coefficient- is the number that is attached to the variable.
Constant is the number that stands alone. You must be very familiar with these terms and use them in class.

As always in MATH,
