Tetration is iterated exponentiation, like how exponentiation is iterated multiplication. Tetration can be defined recursively as: | Tetration is iterated exponentiation, like how exponentiation is iterated multiplication. Tetration can be defined recursively as: | ||

For example, a↑↑1 = a, a↑↑2 = a<sup>a</sup>, and a↑↑3 = a<sup>a<sup>a</sup></sup>. | For example, a↑↑1 = a, a↑↑2 = a<sup>a</sup>, and a↑↑3 = a<sup>a<sup>a</sup></sup>. | ||
