Clean and intuitive to use. Calculator 42 is one of the best basic calculators. The calculator will not let you enter the wrong expression and will prompt you to arrange the brackets. The results of the latest calculations are displayed on the screen. You can configure the number of calculations to output or remove them completely. When you click on the mini history for a long time, the context menu appears: you can use results and expressions again, copy and delete calculations. Also, all other results are saved in the calculation history for further use, which can be viewed and edited. You can delete all calculations in the app settings.

Happy calculations!
