Listening Anzan: mental arithmetic with numbers read aloud
How it works
Your device reads the numbers aloud, one after another, and says "minus" before a number to subtract. When it finishes, type the total.
This is the listening round of abacus contests such as UCMAS, known in Japan as yomiage anzan. You choose the digits, how many numbers, the reading speed and the pause between numbers.
Good to know
The voice comes from your device, so it depends on your browser and system. Chrome, Edge and Safari have the most voices. The voice follows the language of the site.
