 ### Mathematical operations calculator must support
 * Arithmetic (`+`, `-`, `*`, `/`, `//`, `%`, `^`) (`^` is a power).
 * Comparison (`<`, `<=`, `==`, `!=`, `>=`, `>`).
-* 3 built-in python functions: `abs`, `pow`, `round`.
+* 2 built-in python functions: `abs` and `round`.
 * All functions and constants from standard python module `math` (trigonometry, logarithms, etc.).
