Calculator is ready to perform the following tasks:
- calculate a numeric expression with common and decimal fractions, parentheses, power, square root and percentages;
- show a short and detailed version of the solution in one of three ways - in decimal fractions with a given accuracy (like a regular calculator), in common fractions or mixed numbers;
- simplify the expression and factorize;
- solve a linear or quadratic equation. For a quadratic equation with fractional coefficients, there are 2 solutions: either with the specified coefficients or with the reduction of the coefficients to integers (by default);
- solve a cubic equation;
- solve the inequality or a system of 2 or 3 inequalities with one unknown;
- compare two numeric expressions;
- translate a common fraction to a decimal and a decimal to common fraction;
find a LCM, GCD, all the divisors and prime factors of multiple numbers;
- reduce, reduce to a common denominator and compare multiple fractions;
- calculate the proportion;
- plot graphs of a linear, quadratic and others function. (To plot a graph, specify an expression with ' X ' without the '=' sign).

The advanced capabilities of the calculator:
- using parameters (letters) instead of numbers to expressions and equations;
- replacing parameters with numeric values;
- substitution of expressions (use to solve the system of equations);
- long division for solving tasks in decimals (the check box in the menu to show or hide long division);
- long division for polynomials.

Additional information:
- voice input of the task is available (voice calculator);
- three switchable windows with shared memory for working with three tasks;
- saving intermediate results in a task log (temporary memory) for further use (for adding, substituting);
- storing examples in permanent memory;
- it is possible to print the solution or save it in a file;
- groups of screen elements, including the keyboard, are scaled separately for optimal adjustment for different screens;
- for the background, you can connect a picture from the gallery.
