Fractions.Equations.Inequality

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.
