Love it Okay, this one is amazing, also great learning tool. I am like okay what if I do this? Okay, now what if do this? Flexibility allows adding to the equation anywhere in the equation, and changing any part of the equation. Save it. Reload it later then work it from a different angle. I should have been asleep hours ago. Simply amazing!

keith bryant

This app makes complex math simple All I wanted was a simple calculator for doing percentages, but when I tried this app I found it to be so much more. Very easy to use, and very customisable. Well worth paying for pro version.

Mark Coyle

Love it The free version is great. The pro version is even better. For what it costs it's well worth it. I love this app. Thanks:-) :-) :-) :-)

User reviews

Awesome. Simply awesome. I no longer need a stand alone calculator. Doesn't graph, but I don't need that. Solves all manner of equations and gives a plethora of solutions. It's what I wished I'd had in algebra class!

Mathlab Apps, LLC June 4, 2014

Just in case, we have a Graphing Calculator also. Here is its FREE version: https://play.google.com/store/apps/details?id=us.mathlab.android Here is its PRO version: https://play.google.com/store/apps/details?id=us.mathlab.android.calc.edu Here is a video how to plot graphs etc: https://www.youtube.com/watch?v=doIYR6hUCpg Good but My but is if you add plus or minus sign for quadratic equations will be awesome. Then I will give the app 5 stars.

Mathlab Apps, LLC December 1, 2014

If we add plus or minus sign for quadratic equations, it will confuse a lot of users who have difficulties to read math formula easily. Users from some countries don't even have textbooks to learn math. We need to keep everything simply understandable because many people use the app to learn math. Very nice calculator! No fraction app in google play comes even close. Take a look at the best calculator ever from the same developer: Graphing Calculator Pro! You won't believe how powerful and elegant a calculator can be!

Mathlab Apps, LLC October 23, 2014

So nice to get your feedback again! Thank you very much, Ze, for your appreciation and for buying even both apps! We will make both apps even better. Lets the math will be the simplest for all people all over the world. Lets everyone learn and comprehend math with ease :) Great calculator for fractions I used the free version many times when checking homework. I got the paid app and it is a great calculator for fractions. It has saved me a lot of time.

Mathlab Apps, LLC November 9, 2014

Thank you, Brian, for your appreciation of our work and for your financial support! We really appreciate it and try our best to help all people all over the world to learn math by the easiest way. Try our free even more powerful app, the Graphing Calculator y Mathlab: https://play.google.com/store/apps/details?id=us.mathlab.android Love this app This is a GREAT app. I use it to double check my son's homework. If he has an answer wrong, it is so helpful to be able to see each step to help us show him where he had made an error so that he can fix it. Highly recommended for any parent!!!!

Mathlab Apps, LLC September 15, 2014

It's so nice that parents use our app also! We wish your son always get only "A" for all math courses. Btw, our Graphing Calculator by Mathlab (FREE or PRO) has even better functionality. People use it for middle, high school and college math courses. You may try that great app also: https://play.google.com/store/apps/details?id=us.mathlab.android Really like but wish one thing Great app and when dividing fractions if you use the ÷ sign between fractions it will show you division by inverting the second fraction and multiplying. Great tool for teaching.
