AWESOME!!!! MENTAL MATH PLUS ME EQUALS A TOTAL NIGHTMARE! I HATED Mental Math! So this App is useful!

This is especially good for me because... This is great for me because I am doing tuition for my 11+ which is in about two months so instead of doing my practice papers I use the apps now instead! I love doing the times tables as they are like my training before my actual test so that is awesome. The only thing that I would change is that when you so the flash calc that you can say if you want it to be addition, subtraction,multiplication or division because doing addition all the time isn't the most exciting thing ever!!! I just want to say thanks

Suggestions This app is by far the best mental calc app in the store. I've tried the top ten and this works the best for me. To see this great project improve, I have 3 suggestions. More techniques. A log for 'training'. And a standardized daily worldwide calc competition scoreboard. It'd give your downloads a great boost. Best of luck, dev.

... While I like the look and feel better than the others, I don't like the ads and would rather pay a buck or two to never see them again, ever. Update- ads now cover the buttons crippling the app. I believe this is a poor practice and maybe against Goole Play's Terms of Service. No choice but to remove stars.

Great mental arithmetic trainer. This app does exactly what I hoped it would: train my ability to do arithmetic fast and (mostly) error free. I particularly like the tutorials an calculating techniques. The app does display advertisements (what I don't like), but it does it in a way that's not overly intrusive.

Fantastic A great little app. Good for memorizing multiplication results if you've forgotten them since school. Some good techniques on doing mental math in the tutorial section (i.e. 54x9 = 54x10-54). I have no complaints at all about this software. I recommend it if you want to improve your mental calculation skills.

Great apps Its a great apps. Will be better with score and optional time limit. Too fast for kids

Mathematics is a powerful calculation software for your android smartphone.

FEATURES

Calculate any formula you want and show them in a 2d or 3d plot. The natural display shows fractions, roots and exponents as you would expect it from mathematics.

In a few seconds you derivate or integrate your desired function, calculate the zero points of your function und show them in the function plot. See all maxima, minima or inflection points in one view.

The easy way of use allows you to solve linear equations in just a moment. Or transform your mathematical, physical or chemical equation to any unknown variable.

You often needs to calculate with binary, octal or hexadecimal number systems? No problem! You can mix them together in one calculation even by using decimal digits. But that's not enough! You can also calculate with any other number system with base 2 to 18.

From time to time you may need to convert units to another one, like Celsius to Fahrenheit, miles to kilometre, inches to foot and so on.

You will also be able to calculate with vectors, matrices and determinants.

All this features are combined in this app and will make your mathematical life a lot easier.
