text: # Kambei Mori
  
  Kambei Mori or Mōri Kambei (毛利 勘兵衛), also known as Mōri Kambei Shigeyoshi Mōri Shigeyoshi (毛利 重能), was a Japanese mathematician in the Edo period.
  
  ## Life and work
  
  Some 16th-century sources suggest that Mori studied in China, but such claims are inconclusive or rejected by historians. What is known with certainty is that he started a school in Kyoto and he wrote several influential and widely discussed books which dealt with arithmetic and the use of the abacus.
  
  One of his students was Yoshida Mitsuyoshi, the author of Jinkōki, which is the oldest extant Japanese mathematical text.
