History and Functionality
According to its designer, John BERGMANN (Germany), this calculator is universal:
“A subledger applicable to any kind of math! It replaces and exceeds all existing calculating machines! This is a real success of our time! Consulting the tables is finding the product!”
This table enables multiplication of five digits, division by two digits, calculations of profit on sales prices, English and French currency conversions, calculations of prices, and computation of discounted interests.
