*Tetration is called iterated exponentiation.

*The notation <math>^n a</math>  means <math>a^a^a\cdots</math> the application of exponentiation <math> n-1</math> times.

*The notation <math>^n a</math>  means <math>a^a^a^\dots</math> the application of exponentiation <math> n-1</math> times.

*Tetration is simply defined by:For any positive real  a>0 and non-negative integer {\displaystyle n\geq 0} n\geq 0, we define {\displaystyle \,\!{^{n}a}} \,\!{^{n}a} by:
