– It is rated above 4.9 on Google Play with many positive reviews.

Here are just a few user reviews:

> "Perfect companion for the challenges on the linear and probability theories!"

> "Thanks to the authors, for a nominal fee I bought the app without thinking, it will probably cost more for the test for mathematics"

> "Great app. I bought it and don’t regret it. "

This application is a universal assistant for those who deal with advanced mathematics. You can be a higher school student, a university student or even a graduate – If you need immediate mathematical assistance – MathHelper is always at hand!

You can forget about all the heavy books and numerous tricks with the tips, which in most cases do not guarantee that you’ll solve your maths problem.

MathHelper enables you to not only to solve the problem, but also to understand the process of solving it, step by step. This convenient multifunctional calculator includes an extensive theoretical guide in several languages. You’ll get an algebraic mini-laboratory that is stored conveniently and compactly on your Android!

Now, you can not only quickly find the answer, but also handle similar problems in the future. Your classmates and teachers will be very surprised with the results of your work.

MathHelper is indispensable during your math exams! And even if you have already grown out of school uniform and student’s jeans, you can always use a universal mathematical reference book calculator!
