Aida Yasuaki, also called Aida Ammei, was born in Yamagata, Japan on February 10, 1747 (March 20, in the present calendar). Aida studied mathematics under Okazaki Yasuyuki, a mathematician of the Nakanishi‐ryu school, from the time he was 15 years old until he reached the level of the Tianyuanshu technique (Chinese Algebra system).
Then he went to Edo (now Tokyo), in September 1769 and became a son‐in‐law of SUZUKI Seizaemon, a Samurai of the Shogun. Aida changed his name to SUZUKI Hikosuke and worked as a Fushin’ yaku, a civil engineer. Here he came to know KAMIYA Teirei, a student of FUJITA Sadasuke (1734–1807). Fujita was a mathematician of the Seki‐ryu school who wrote the Seiyo Sampo (Exact Mathematics, 1781) which was one of the best mathematical textbooks of that time.
Aida decided to become a mathematician, retired from his work, changed his name back to Aida Yasuaki, and asked Fujita if he could teach mathematics. Fujita did not accept Aida's offer because he was concerned...
- Aida's works are discussed in vol. 4 of Fujiwara Matsusaburo 1956. One of the more complete works is Hirayama and Matsuoka 1966. Most of his works are kept at the Yamagata University Library http://www.lib.yamagata‐u.ac.jp/rarebooks/sakuma_1‐1280.html#anchor1150321.
