Will you use the abacus instead of the calculator?
Does not the brain degenerate with a calculator?
There seem to be various effects such as "The calculation ability goes up", "Working of the brain is improved", "Improvement of the memory", "Improvement of concentration", "Improvement of the conception power", and "Improvement of the information processing ability" in the abacus.
Please strengthen the brain with the abacus calculator.
