Excellent scientific calculator with step-by-step solutions, symbolic algebra, graphing, equations, integrals and derivatives. The calculator has globally more than 50 million downloads and 250 000 five-star ratings. You can write expressions in a natural way and watch your calculations. The result is displayed as a number, simplified expression etc. An expression can also be entered from a photo. Take a picture of a handwritten or printed expression, and the calculator recognizes it and inserts it into the display, ready to be edited or evaluated. (premium) A step-by-step solution shows how an expression is solved, one step at a time, from the entered expression to the final result. Every step is explained, so you can see not only the result, but also the way to it. (more detailed steps are premium) Calculation details give you extended information about the result - alternative forms of the result, all complex roots, the unit circle, properties of a function and more. The calculator has several layouts suitable for various screen sizes: - "pocket" for small devices - "compact" for smartphones (in portrait and landscape orientation) - "expanded" for tablets Users can choose from several high-quality themes. The calculator has many functions, such as: - up to 100 digits of significand and 9 digits of exponent - basic arithmetic operations including percentage, modulo and negation - fractions and mixed numbers - periodic numbers and their conversion to fractions - unlimited number of braces - operator priority - repeated operations - selecting a part of an expression and applying context operations to the selection - equations (with one or more variables, systems of equations) - variables and symbolic computation - derivatives and integrals - graphs of functions, equations, integral area and limits; 3D graphs - matrices and vectors - statistics - regression analysis - complex numbers - conversion between rectangular and polar coordinates - sums and products of series - limits - advanced number operations such as random numbers, combinations, permutations, common greatest divisor, etc. - trigonometric and hyperbolic functions - powers, roots, logarithms, etc. - degrees, minutes and seconds conversion - fixed point, scientific and engineering display format - display exponent as SI units prefix - memory operations with unlimited extended memories - clipboard operations with various clipboard formats - result history - multiline display on tablets showing the complete history of calculations and access to the previous results - binary, octal and hexadecimal numeral systems - logical operations - bitwise shifts and rotations - more than 120 physical and mathematical constants - conversion among 250 units - Reverse Polish notation.

"Permutation Combination Calculator" is an application that makes it easy to perform calculations for permutations and combinations commonly used in mathematics and statistics. By using this app, even those who are not good at mathematical calculations can easily perform calculations. The app is equipped with functions for performing permutation and combinatorial calculations. In permutation calculations, you can find the number of cases where r elements are selected from n elements. Combinatorial calculations, on the other hand, allow you to find the number of cases where r elements are selected from n elements, disregarding the order. In web-based examinations with strict time limits, reducing the time spent on calculation questions can free up time to answer other questions. By allocating your time appropriately and using the "Permutation Combination Calculator", you can take the web-based examinations efficiently and accurately.
