elementary

adj. basic, fundamental

In computational complexity theory, the complexity class ELEMENTARY is the union of the classes in the exponential hierarchy. The name was coined in the context of recursive functions and undecidability; most problems in it are far from elementary. Some natural recursive problems lie outside ELEMENTARY, and are thus NONELEMENTARY. Most notably, there are primitive recursive problems which are not in ELEMENTARY. We knowLOWER-ELEMENTARY  EXPTIME  ELEMENTARY  PR Whereas ELEMENTARY contains bounded applications of exponentiation (for example, ), PR allows more general hyper operators (for example, , using Knuth's up-arrow notation) which are not contained in ELEMENTARY.
