The cultural property is a thing that was dedicated to Yusu Kannon-do (the tangible cultural property designated Iwate Prefecture in 1994) by Yuho Nagasaburo (Kokisei) of Kamisuzawa-mura in Kanpo 3 (1743) and April. Mr. Uo has succeeded to the Shinto shrine and has reached the present.
The said calculation amount becomes Tono City designated tangible cultural property in 2000 (2000) (we take over old tangyura village designated tangible cultural property by merger of municipalities), and, along with other votives dedicated to Shiso Kannon Temple since ancient times, It is stored in the ema storehouse built in 1981 (1981).
As for the contents of the calculation, two questions and "Attached gold and silver percentage" are published. The first question is the present-day problem of the Tengen-gen technique (Ju-tsu) (how to solve higher-order equations using math-san-gi-gi-san-ban-ban) Correspond to high school mathematics B, but it is difficult to reach the solution method. The second question is the so-called "Tsurukame calculus", which is a problem from modern elementary school to junior high school. "Golden and silver percent" relates to the conversion of gold and silver coins and coins.
Although the content is an algebraic problem, it is said that there are many geometric problems due to the appearance of figures in arithmetic, and it is said that algebraic arithmetic is only about 10%. That point is also rare.
There are 99 existing figures in Iwate Prefecture, and 172 figures have been dedicated (made) if historical figures include the remaining record figures. The said calculation amount is the eighth following the calculation amount of Kanegasaki Hachiman Shrine (1950 <1980> Iwate designated tangible cultural property) in the order of dedication (production) among the existing calculation amounts of the whole country. It is the eighth oldest in the country, the second largest in the prefecture, and the oldest existing in the Morioka territory. It is a valuable resource to know the spread of the addition to the region.
