A software to practice anzan
Anzan is the mental calculation you perform while visualizing a soroban in your head.
A little pyQt software
To help me practice, I have also made a little program in python and pyqt. It's called Mental Calculation (how original !)
You can choose how many numbers to add, how many digit each number have, the time between the display of each number (called timeout) and the time a number stays on screen (called flash).
You can also have each number said to you by a speech synthesizer. It required a working Internet connection as requests are made for each sound.
Replaying a sequence
You can replay any sequence for your convenience. Just press the 'Replay' button if you missed some number.
You can use it full screen, and/or in a continuous mode where you don't have to enter an answer and to interact with the keyboard. It goes on ad infinitum.
Note: Various options can be changed from the configuration file. See the README to find out how to change them.
Try it yourself!
You can download the latest version 0.5.2
If you're willing to translate this little program into your language, go to the forum where you'll find more details about this.
and also with a sheet of paper
Go to the generator page and choose the anzan tab to get an XLS file with anzan exercises.
and also in your browser
You can now practice anzan in your browser (being mobile or not) with the following dedicated page. There is a range of options to customize your anzan practice. You can choose the language used by the speech synthesis. And don't forget to go full screen on mobile for a better experience (the link is in the menu bar).
