16. Abacus Math Contest Tests Speed and Accuracy

An abacus and mental arithmetic competition was held in Okayama Prefecture in late August. In the "Flash Anzan" event, 15 sets of three-digit numbers were flashed consecutively on a screen, and competitors added the numbers in their head. The numbers were gradually sped up, and in the end 15 numbers were displayed in 2.2 seconds. We review the news story in Japanese and learn expressions related to math such as "tasu" (to add) as well as other useful vocab words for everyday life.
