Impress Launches On-Demand Course Combining Adult Arithmetic E-Book and Video Lessons for People Uncomfortable with Numbers

Impress Corporation, an IT media business under the Impress Group, announced that it will begin streaming the on-demand course Video-Based Quick Course: Adult Arithmetic Relaxed Training on Friday, May 15, 2026. The course combines a PDF e-book edition of the popular book Can You Solve This? Adult Arithmetic Relaxed Training to Stop Being Afraid of Numbers with practical explanatory videos, helping adults who struggle with numbers relearn arithmetic through familiar everyday topics. The course proposes a new approach to overcoming number anxiety by shifting from memorizing procedures to understanding what numbers mean. In business settings, Excel and AI can instantly output figures, but many professionals still feel uncertain about whether those numbers are correct and how to interpret them. Impress notes that much of this discomfort comes from getting through school arithmetic by memorizing methods without understanding the underlying concepts. The course condenses the know-how of Otonajuku, an arithmetic and mathematics school for adults that has taught more than 6,000 learners. Linked with the book’s content, the 2-hour-and-20-minute video lessons explain essential business concepts such as ratios and fractions, while also training logical thinking through problems such as crane-and-turtle problems and work-rate problems. The course aims to improve numerical literacy while lowering psychological barriers. Learners revisit practical concepts such as year-on-year change and profit margin from the basics, develop logical thinking skills through exercises, and acquire the ability to correctly evaluate and interpret numbers produced by tools. By carefully explaining meaning instead of relying on rote memorization, the course is designed to free learners from long-standing number-related insecurity and workplace stress, build confidence at work, and help them visualize numbers more concretely in daily life. Key features include a hybrid format combining a proven book with explanatory videos, visual explanations using slides, and a PDF e-book for self-paced review. The course emphasizes understanding the meaning behind business numbers rather than memorizing formulas, covering directly relevant topics such as year-on-year comparisons and composition ratios. It also helps learners overcome arithmetic anxiety through familiar examples and is delivered via Coeteco College, allowing learners to study anytime from a PC or smartphone. The course is recommended for people who need to work with numbers but strongly dislike arithmetic, those who want to properly understand and evaluate the meaning of numbers output by Excel or AI, those who want to relearn concepts such as year-on-year change, composition ratio, and profit margin from the basics, and those who want to strengthen logical thinking and gain confidence at work. The 140-minute curriculum covers guidance, multiples and divisors, fractions, algebraic expressions, equations, sets, crane-and-turtle problems, units, work-rate problems, ratios, rates of increase and decrease, composition ratios, year-on-year comparisons, profit-and-loss problems, various percentage concepts, how to read tables, and cross-tabulation tables.
