The 21 best apps for solving simple and complex math problems


As we all know, in all versions of windows, the classic computer (calculator) that helps us perform mathematical operations has remained almost the same for many years without much emphasis being given to its development. 

Therefore for those who want to do complex mathematical operations such a thing is impossible. If you search, you will definitely find several third-party applications that can fill this gap, and in fact, several of them are available completely free. 

Today, we present the 21 best math problem solving apps, hoping to cover everyone from the most ignorant to the very advanced.
