Students know the hardships of having to solve complex math equations with little time on their hands. And if you fit that description, you might want to check out AutoMath Photo Calculator from the Google Play Store. The app can simply look at an image containing a math equation and provide you with the answer in no time.
What's even better is that it will also show a step by step guide on how to solve the problem on your own. AutoMath can perform over 250 mathematical functions and without requiring an internet connection. The app can handle Addition, Subtraction, Multiplication, Fractions, Division, Inequalities, Powers, Square Roots, Trigonometry, Algebra, Simplification, and Basic Algorithms
AutoMath can also be used to train yourself in some every day math, so it's not necessarily limited to students and academics. It is a free download from the Google Play Store, which is rare for an application of this caliber. You can download the app on devices running Android 2.3.3 and above.
I have seen some applications that could offer the same feature like this one. For me, it’s a good tool for the students but it is always better if a student will try to use their knowledge in solving for the right answer and create their own solution for the problems that they are facing in mathematics.
