“Oral Counting in a Village School”, a painting by the Russian artist Bogdanov-Belsky, created in 1895, offers a fascinating glimpse into the educational practices of the time. The scene depicts a classroom where young students, around 9-10 years old, are engaged in solving a complex arithmetic problem written on the blackboard:
(10² + 11² + 12² + 13² + 14²) / 365
Remarkably, one of the students has already worked out the solution in his head and is whispering the answer into the teacher's ear.
