Question | Answer |
---|---|
Algebra | The branch of mathematics that involves expressions with variables. |
Algebraic Expression | A combination of variables, numbers, and at least one operation. |
Arithmetic Sequence | A sequence in which each term is found by adding the same number to the previous term. |
Base | In a power, the number used as a factor. In 10^3, the base is 10. That is, 10^3 = 10 × 10 × 10. |
Coefficient | The numerical factor of a term that contains a variable. |
Defining The Variable | Choosing a variable to represent an unknown value in a problem, and using it to write an expression or equation to solve the problem. |
Domain | The set of input values for a function. |
Equation | A mathematical sentence that contains an equals sign, =. |
Equivalent Expressions | Expressions that have the same value. |
Evaluate | To find the value of an expression. |
Exponent | In a power, the number that tells how many times the base is used as a factor. In 53, the exponent is 3. That is, 53 = 5 × 5 × 5. |
Factors | Two or more numbers that are multiplied together to form a product. |
Function | A relation in which each element of the input is paired with exactly one element of the output according to a specified rule. |
Function Rule | The operation performed on the input of a function. |
Numerical Expression | A combination of numbers and operations. |
Order of Operations | The rules to follow when more than one operation is used in a numerical expression. |
Perfect Squares | Numbers with square roots that are whole numbers. 25 is a perfect square because the square root of 25 is 5. |
Powers | Numbers expressed using exponents. The power 3^2 is read three to the second power, or three squared. |
Radical Sign | The symbol used to indicate a nonnegative square root, √. |
Range | The set of output values for a function. |
Sequence | A list of numbers in a certain order, such as 0, 1, 2, 3, or 2, 4, 6, 8. |
Solution | A value for the variable that makes an equation true. The solution of 12 = x + 7 is 5. |
Square | The product of a number and itself. 36 is the square of 6. |
Square Root | One of the two equal factors of a number. The square root of 9 is 3. |
Term | Each number in a sequence. |
Variable | A placeholder, usually a letter, used to represent an unspecified value in mathematical expressions or sentences. In 3 + a = 6, a is a variable. |
