About

Liri Calculator is a Material Design application that solves mathematical equations. At first it appears to be a simple calculator with only basic arithmetic operations. However it features a flexible expression parser with support for symbolic computation, a large set of built-in functions and constants and works with different data types like numbers, big numbers, complex numbers, fractions, units and matrices.
