Algebraic Expressions

• An algebraic expression differs from an open sentence or equation in that it has no equal sign.
• The value of an algebraic expression can vary depending on the value of the variable.
• Within a single problem, the value of the variable remains the same.
• A variable is a symbol that represents one or more numbers. A mathematical expression with one or more variables is an algebraic expression. To evaluate an algebraic expression, replace each variable with a number and then simplify.
