yExpression light app for iPhone and iPad

The most important advantage of this calculator is: it is an expression based calculator. Compared with normal calculators this expression based calculator shows you always the numbers and operators you have entered. You know what you calculated.

This app makes you much easier and more convenient by calculating of a lot of numbers in a complicated structure in one step. E.g.

12.43 x (123.65 / 9.34 + 1.7 / (2.33 – 12.65 / 7.88) – 12.3 x 0.44) + 1.65 – 2.7
= 125.3960798

or

12345 x (987 + 624 – 1266 / 3 x 5 + (12908 + 5528) / 2) – 456 + 7 x (756 – 237)
= 107639232

This app, the light version of yExpression, supports addition (+), subtraction (-), multiplication (x) and division (/).

The app supports English, German and Chinese.

For expression based calculation including advanced mathematical functions like exponential function, logarithmic function and trigonometric function, please use the standard version of the app: yExpression.
