Some of the challenges are pretty good and well balanced. It reminds me of a basic version of the early Nintendo DS brain games. However, the math problems do not follow order of operations and end up having wrong answers.

Great app, yet simple UI and entertaining. There's a bug within tests having calc, when the calculation become too long, the backspace button moved out of screen (invisible). Thank you!

Great! Except on mental calculation numbers are missing in some of the equations, if that gets fixed it'll be 5 stars

Sorry for the inconvenience. I updated the app to make the rules for Mental calculation more clear. The rule is to remember the result of the previous calculation and use it as a base for the next calculation. E.g. if the previous result was 3 and the current calculation is "* 5" the result is 15. I also updated the Anomaly puzzle, Thanks
