A four-function calculator is the simplest type of pocket calculator and is suitable for basic arithmetic.

Scientific and graphing calculators can perform computations on data sets and have built-in complex functions such as linear regression. In some math courses, scientific and graphing calculators are prohibited during exams because students are required to perform these complex functions without assistance.
