**DESCRIPTION:**

**Calculators were one of the most revolutionary tools in the last century and they were able to greatly change our world and make all kinds of calculations easy. Before the advent of calculators, people had to use their minds and paper tools to do all the calculations. This would increase the time needed to perform calculations and increase the probability of errors in calculations. With calculators, humans could leave calculations to electronic devices and leave their minds free to cultivate other ideas and thoughts. Calculator applications were among the first applications that were installed on smartphones. In such a way that now a calculator application is installed on all smartphones by default. Of course, these programs are replaced by users with other calculator applications due to their low features and limited capabilities. Today we are at your service with a great calculator to replace the default Android calculator. Scientific Calculator 300 Plus is an advanced calculator application for the Android operating system developed by nhipham and published for free on Google Play. This calculator is able to solve all your calculation needs and provides you with a variety of features that make you unnecessary to install another program. For example, you can use this program as a simple calculator or use it to perform calculations such as integral calculations, solving equations, calculating exponential expressions and other types of calculations. To avoid complicating the user interface of the program, related tools are placed in separate sections. For example, a section for a simple calculator, a section for an advanced calculator, a section for performing calculations related to programming, a section for drawing graphs of mathematical expressions, and other sections for performing calculations related to chemistry are embedded in this program. Is. Mathematical expressions in this program are displayed in the same way as they are written on paper, so that it is easier for the user to understand them.**

**Scientific Calculator 300 Plus was developed specifically for use in applications related to science and engineering. It is an actual calculator that has a lot of different functions that it can perform. As a result of this factor, this calculator is the most suitable calculator for usage in academic settings.**

**In addition to calculators for algebraic and trigonometric functions, the Scientific Calculator 300 Plus also includes calculators for logarithmic and trigonometric functions. This calculator also includes calculators for percentages, powers, roots, trigonometric, and logarithmic functions. It allows you to perform operations such as multiplying fractions, converting fractions to decimals, and solving problems that involve fractions. It combines the capabilities of a hyper calculator and a regular scientific calculator into one convenient device. This is a calculator that is both highly functional and adaptable. Results are always displayed in both rectangular and polar coordinates, regardless of whether the subject studied is linear algebra, calculus, complex numbers, matrices, or vectors.**

**Equation-solving capabilities are built into the software in a complex form. Equation solvers allow for the resolution of not only individual equations but also entire systems of equations, including quadratic and cubic equations. Any polynomial can be solved by using the calculator. In addition to various scientific operations such as a derivative calculator, integral calculator, square root calculator, factorial calculator, pi calculator, and equation solver, the Smart Scientific Calculator features an exponent calculator. Investigate the concepts of prime numbers, random integers, permutations, combinations, GCD, and LCM with any number of digits you like. This package includes a sophisticated calculator that can integrate, differentiate, integrate, and differentiate. With the assistance of this scientific calculator’s built-in CAS, you are able to carry out calculations involving symbols (computer algebra system). A math formula, a physics formula, unit conversion, a theme, a typeface, and even programming are some of the additional elements that are included.**
