No ads! Completely free super calculator ~ An intelligent student calculator that integrates scientific calculations, calculators, fraction calculators, unit conversions, fourth equations of one variable, function curves, polynomial decomposition, calculations of degrees, minutes and seconds, trigonometric functions, inverse trigonometric functions, fraction calculations, permutations and combinations, common denominators, common multiples, factorials, absolute values, remainders, logarithm operations and other intelligent operations. It has no ads and small memory. It is easy to use and will pass every exam!
Student Calculator is a multi-functional, compact and lightweight calculator tool application without advertising. It is perfectly suitable for any computer model. It covers standard four calculations, scientific calculations, unit conversion and other functions, and has historical records.
The operation of the calculator is more realistic than other calculators on the market. You can modify calculation formulas by moving the cursor, display historical records by date, and make notes on historical records and edit calculations again. Added history lock function, the locked history will not be cleared when clearing the history!
Switch between dark mode and light mode at will!

Function introduction:
【Standard Calculator】
1) It supports basic operations such as addition, subtraction, multiplication and division that are used in daily life. It is easier to use than the built-in calculator and is easy to operate.
2) Supports the function of viewing historical records. No matter how complicated the process is, the process will not be remembered incorrectly. The historical process is completely saved and the historical records can be commented and re-edited.
3) Edit the input box again, drag the cursor arbitrarily, and modify the formula results at will, which is convenient for checking and re-reading without making mistakes.
【Scientific Calculator】
1) Supports scientific calculations of formula operations, logarithmic functions, power functions, trigonometric functions, and inverse trigonometric functions
2) Supports factorial, angle and radian operations, square operations, calculation of degrees, minutes and seconds, etc.
3) Supports quadratic equations of one variable, function curves, polynomial decomposition, fraction calculations, permutations and combinations, common divisors, common multiples, factorials, absolute values, remainders, linear functions of one variable, inverse proportional functions, quadratic functions of one variable, exponential functions, logarithmic functions, circles, ellipses, hyperbolas, parabolas, etc.
【Unit conversion】
Supports length, area, volume, mass, temperature, pressure, power, heat, force, density, time, speed, angle, storage, and base unit conversion
