Term | Definition |
---|---|
Algebraic Expression | A mathematical phrase involving at least one variable. They can contain numbers and operation symbols. |
Cube Root | One of three equal factors of a number. For example. 3 x 3 x 3 = 27, so 3 is the___________ _________ for 27. |
Exponent | The number of times a base is used as a factor of repeated multiplication. |
Equation | A mathematical sentence that contains an equals sign. |
Inverse Operation | Pairs of operations that undo each other, for example, addition and subtraction OR division and multiplication. |
Irrational | A real number whose decimal form is non-terminating and non-repeating . This type of number cannot be written as the ratio of two integers. |
Like Terms | Terms that have the same variable raised to the same power. Only the coefficients of these terms can be different. |
Multiplicative Inverses | Two numbers that when multiplied together equal 1, for example, 4 and ¼. |
Perfect Square | A number that has a rational number as its square root. |
Radical | A symbol that is used to indicate finding the root of a number. √ |
Rational | A number that can be written as the ratio of two integers with a nonzero denominator. |
Scientific Notation | A representation of real numbers as the product of a number, where the number is 1≤ n<10, and a power of 10, used primarily for very large or very small numbers. |
Square Root | One of two equal factors of a nonnegative number. For example, 5 is this for 25 because 5 • 5 = 25. -5 is also this for 25 because (-5) • (-5) = 25. |
Variable | A letter or symbol used to represent a number. |
