imikotoba 🏴❤️🇯🇵Eldest continues #soroban (Japanese abacus) 🧮 classes, including mental arithmetic #FlashAnzan techniques & regular drill practice on the computer…
This is currently a crazy physical and mental exercise where they run away from the computer, read the numbers to tally at a distance, then run back and type in answer 🤣
Apparently this helps maintain a small mental model in their (imaginary) field of view, leaving room for larger numbers in future. With some physical exercise as a bonus?

NelsonCan anyone recommend resources for learning to use an abacus? Physical media preferred, but websites are also ok. English language please.
I have a Chinese-style (suanpan) and two Japanese-style (soroban) abacuses. I'm especially interested in advanced techniques that you would need if you were replacing your calculator with an abacus.
Are there other abacus types useful for specific calculations?
I find the Lee Kai-chen Abacus fascinating: http://totton.idirect.com/abacus/Lee/
Jonathan LamotheOkay, my first #Emacs package is officially released. It was strongly inspired by @sorobanexam's work, providing practice tools for the #soroban. This is the first Emacs package I've ever released. It's probably not perfect, but I welcome feedback on how it can be improved.
I wonder if there is an overlap of more than say five people who are both soroban and emacs users. 🙃
Anyhow, it can be found at: codeberg.org/jlamothe/soroban
It seems children’s school pencil cases now come with integrated little calculators in Japan - guess they don’t often have no calculator exams or tests? At least with #FlashAnzan techniques the #soroban is in your own head 🧮🧠

Andrea NavarroEstuve probando PyQt5 y desarrollé una aplicación sencilla para generar operaciones matemáticas aleatorias para practicar con mi soroban.
Por ahora permite elegir el tipo de operación y la cantidad de dígitos, y mostrar el resultado al presionar Enter
