Description

A lively collection of mental‑calculation challenges springs from the notebooks of a 19th‑century village schoolmaster. Designed for everyday arithmetic, the problems draw on the rhythms of rural life—buying land, counting days, measuring cloth, and converting old Russian units. Each task is presented in clear, concise language, inviting listeners to step into the teacher’s chalk‑dusted classroom.

The set covers a broad spectrum of topics: price‑finding for dozens of “десятин” of fields, daily spending over a year, and the conversion of archaic measures such as аршин, вершок, and пуд. Short, self‑contained questions are followed instantly by their solutions, making the material perfect for quick practice or classroom drills. The problems encourage quick mental work, reinforcing number sense while keeping the mind agile.

Beyond the numbers, the book offers a glimpse of historical Russian countryside commerce and customs. Listeners will sense the charm of a bygone era while sharpening their calculation skills, all in a format that feels both educational and entertaining.
