How to Use the 1920/2 Calculator: Tips and Tutorial

Introduction

The 1920/2 calculator, also known as the Brunsviga, is a mechanical calculator that was first produced in the 1920s. It was widely used in businesses and offices before the advent of electronic calculators. The Brunsviga was renowned for its reliability and accuracy, and it could perform complex calculations quickly and efficiently. In this article, we will provide you with tips and a tutorial on how to use the 1920/2 calculator.

Parts of the Calculator

Before we discuss how to use the calculator, it is essential to understand its parts. At the front of the machine is the keyboard, which has ten columns of nine keys each, corresponding to the digits 1 through 9, and the digit zero. There is also a clearing lever, which resets the machine's registers to zero.At the top of the keyboard are a series of control knobs - these allow the user to set and reset different registers and functions. Finally, there is a carriage that moves left and right when the user turns the handle of the machine.

Basic Operations

The 1920/2 calculator can perform the four basic operations - addition, subtraction, multiplication, and division. To add, the user enters the two numbers and presses the plus key (+). The result appears on the output register, which is located on the right-hand side of the keyboard, and the carriage moves to the right.To subtract, the user enters the larger number followed by the smaller number and presses the minus key (-). The result appears on the output register, and the carriage moves to the right.To multiply, the user enters the two numbers and turns the handle of the machine. The result appears on the output register, and the carriage moves to the right.Finally, to divide, the user enters the dividend, hits the division key (/), then the divisor, which is followed by the multiplication key (x) and turns the handle. The quotient appears on the output register, and the carriage moves to the right.

Carry and Borrow Operations

The 1920/2 calculator was designed with carry and borrow operations to allow users to perform multi-digit addition and subtraction efficiently. If a user enters a number that exceeds 9 in any column, the machine carries the extra digit and adds it to the next column. Similarly, during subtraction, if any column in the minuend is smaller than the corresponding column of the subtrahend, the user borrows a digit from the higher-value column.

Square Root and Percentage Operations

The 1920/2 calculator can also perform square root and percentage operations. To calculate the square root of a number, the user enters the number, sets the control knob to the square root position, and turns the handle. The result appears in the output register, and the carriage stops.To perform a percentage calculation, the user enters the percentage amount, followed by the original number, and the multiply key (x). The result appears on the output register.

Conclusion

The 1920/2 calculator is an outstanding mechanical calculator that has stood the test of time. It is easy to use and provides reliable and accurate results. By following our tips and tutorial, you can make effective use of this magnificent machine for your calculations.
