The following section provides a brief review of number properties that are helpful in working with numerical and variable expressions.
Brief Review of Factors
When you multiply two numbers, each of them is a factor.
In this example, both 3 and 4 are factors. In fact, you can write any number as the product of its factors.
Brief Review of Algebraic Expressions and Equations
An algebraic expression includes numbers, operations, and variables and is written in the form of a polynomial.
Here is a simple example of an algebraic expression.
Equations can sometimes consist of algebraic expressions, like the one shown below.
Algebraic Expressions with Coefficients
One type of algebraic expression consists of a number multiplied by a variable. Here is an example.
Both the 3 and the x are factors, but with algebraic expressions, the 3 is also called a coefficient. In these algebraic expressions the coefficients are highlighted in red.
Other Expressions with Coefficients
Here are some other examples of coefficients with exponential, logarithmic, rational, and trigonometric expressions.
