||||
| 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.
🗑
|
||||
