Прочитайте текст и найдите соответствующий перевод подчеркнутого выражения.
Computers originally began as calculators. The first calculator was made by Blaise Pascal. It only had eight buttons, and it could only do addition and subtraction. There was a set of wheels, and all of the wheels had the numbers zero through nine on them. The wheels were connected by gears and each turn of one wheel would turn the next wheel one-tenth of a turn. This machine was completed in 1642 when Blaise was twenty-one years old.
