Practicing anzan

Screenshot of mental calculation

The numbers, when displayed, will replace the soroban image.

Anzan is the mental calculation you perform while visualising 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 !)

Simple configuration

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).

Speech synthesis

You can also have each number said to you by eSpeak, a speech synthetizer. Espeak is a separate software that you have to download and install for this feature to work (and enable speech synthesis in the settings dialog too).

Replaying a sequence

You can replay any sequence for your convenience. Just press the 'Replay' button if you missed some number.

Misc. options

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.

Screencasts

Try it yourself!

It's free (licensed under the GPL). The source code is available on github github octocat logo

You can download the latest version 0.3.5.5

Translators welcome

If you're willing to translate this little program into your language, go to the forum where you'll find more details about this.
