Today’s Business Japanese is “Soroban-Kanjyou”.
“Soroban” is the old and traditional calculator used in Japan for a long time.
“Soroban-Kanjyou” is used as “Calculating Profit/Loss” in good sense.
However, it is sometimes used as “Thinking about one’s own profit” in a bad manner.
For your reference, “Donburi-Kanjyou” means “To be not good at Soroban-Kanjyou” because “Donburi” is a big bowl used for eating soba and udon noodle and it means calculation is not accurate.
