Coefficient | The number that is multiplied by the variable in an algebraic expression. |
Expression | A mathematical phrase containing numbers, operations, and/or variables. |
Constant term | A term that has a number but no variable. |
Evaluate (an algebraic expression) | Substitute a number for each variable in an algebraic expression. Then use the order of operations to find the value of the numerical expression. |
Substitute | to replace a variable with a number or another expression in an algebraic expression. |
Equation | A mathematical sentence that uses an equal sign, =, to show that two expressions are equal. |
Solve | to find an answer or a solution. |
Solution of an equation | A value that makes an equation true. |

Term | the parts of an expression that are added together. |
Like Term | Terms that have identical variable parts. |
Equivalent Expression | Expressions with the same value. |
Simplify | to write a fraction or expression in simplest form. |
Distributive Property | To multiply a sum or difference by a number, multiply each number in the sum or difference by the number outside the parentheses. Then evaluate. |
Order of Operations | The order in which to perform operations when evaluating expressions with more than one operation |
Ordered pair | A pair of numbers (x, y) used to locate a point in a coordinate plane. The first number is the x-coordinate, and the second number is the y-coordinate |
Integer | The set of whole numbers and their opposites. |
Opposite | two numbers that are an equal distance from zero on a number line |
