Solves systems of two linear equations in two variables using Cramer's Rule.

Shows step-by-step solution.

Supports integer, fractional and decimal coefficients.

Shows results as decimals and fractions.

Stores history with the possibility to recall previous equations.

Sends results and history via email.

Supports both portrait and landscape orientation.
