An online calculator calculates a polygon area, given lengths of polygon sides and diagonals, which split polygon to non-overlapping triangles.

This calculator is a solver of cryptarithmetic puzzles. A cryptarithmetic puzzle is a number puzzle in which a group of arithmetical operations has some or all of its digits replaced by letters or symbols, and where the initial digits must be found. In such a puzzle, each letter represents a unique digit.
