#### To learn more about a math statement we often have to simplify or evaluate math expressions. You will need to understand all the terms in an expression to do this. An expression normally consists of two to three parts. The variable is the letter or symbol used to represent an unspecified value. The free form number that is either a negative or positive value is known as the constant. Many times, expressions will also have binomials that contain exponents. In most cases your first item of business is to combine any like terms that may exist. Being able to do this well is the complete key to knocking this one out of the park.

Most of the expressions provide on these worksheets run the expressions through a mathematical system. The values that are fixed and/or shifting within each expression with be positive and negative integers. As students advanced through this section we will introduce fractions to variables to make this just that much more difficult. As you move forward with your math career, you will start to use mathematical expressions to explain or at least figure out things in everyday life. I find myself doing it just to determine the estimated arrival times of flights. These activity sheets will teach your students the differences between expressions and equations, and will show them how to evaluate and solve them. These worksheets explain how to evaluate and simplify expressions using fractions and variables that are included. This section has lessons and plenty of practice problems.
