MalMath
With the help of this app, you will be able to solve math problems, not only getting detailed step-by-step solutions of the calculation process but also building the necessary graphs. The MalMath Android application is completely free and completely ad-free. Also, you can use it without an internet connection. This is a big plus for this app. The program is mainly concerned with the knowledge of high school students and university students, as well as universities and institutes. In fact, MalMath can solve integrals, derivatives, limits, logarithms, trigonometric equations and inequalities, for example with integer and modulus solutions. However, you will have to enter the task condition manually because the camera recognition function does not work.
The MalMath interface is presented in English, German, Spanish, Italian, French, Turkish, Albanian, Croatian, Arabic, Portuguese, Arabic, Russian, and Japanese, and is classically made and optimized for smartphone screens. You have the option to change the font size and animation speed in the settings. When you open the menu, you will see it consists of five items: home screen, sheets, schedule, task builder, and favorites. But most of all, you'll enjoy the "task builder" functionality. With its help, you can generate random problems with several categories and difficulty levels specified in the settings. All expressions and graphs can be saved as favorites. Because the app function doesn't support the photo function, it's sometimes inconvenient, especially when you have to enter complex combinations with fractions and square roots. It takes a bit of time to get used to a certain principle of typing, but it's still worth it.
