A Brief History of the Mechanical Calculator

A calculator is a device that uses mathematical calculations in order to solve problems. It is usually an electronic device which can be used to conduct several mathematical operations in a step-by-step manner. A calculator is designed to help people in performing simple calculations such as addition, subtraction, division and multiplication. However, a calculator can also be used for a wide range of other purposes.

The mechanical calculator was invented in 18 Calculator was invented by Georgeomoncell, a Scottish civil engineer. He developed a new way to add, subtract and multiply numbers by using a lever. This new concept made use of a key-driven calculator that worked on the basis of touchscreens, push buttons and a pointing stick. Since the mid-nineteenth century, mechanical calculators have become more popular because of the ease of operation they provide and the fact that they could be used in schools, at work, and even in church.

One of the earliest mechanical calculators was the Thwaite calculator, invented in England in 1850. The Thwaite calculator was based on the idea of the abacus, where a user can determine the value of a number by using the number itself as a base. In recent years, electronic calculators paved the way for a more versatile and practical device which makes use of the same technology behind the abacus, while introducing many new features. Today, mechanical calculators are still used extensively, although their role has been taken over by electronic calculators.
