The first calculating tools were the abacus and counting boards. To address this need, people created ancient calculating contraptions. Once people began trading, merchants needed a tool to keep track of goods they bought and sold. When that was not enough, they used counters such as pebbles or twigs to track quantities. People used their fingers and sometimes their toes to count objects. This is according to The Abacus: A Brief History, an educational resource hosted by Ryerson University. It’s hard to imagine a world without numbers, let alone count without them. The most ancient calculating device, the abacus, is still used in countries such as Japan, China, Russia, and the Middle East. Meanwhile, non-electronic calculators are still being manufactured. Many of them are solar-powered or run on batteries. With general purpose computing calculators can be represented using software like the below JavaScript calculator.Īside from calculators in cellphones, calculating gadgets are still used today. They allow you to solve calculus, trigonometry, and logarithmic equations. More complex calculators allow you to compute fractions, square roots, and exponents. Most calculators can add, subtract, multiply, and divide numbers. ![]() It comes with a keyboard and a small visual display to input numbers. What is a Calculator?Ī calculator is any electronic gadget that allows you to solve math problems easily. ![]() Finally, we featured a brief history of the abacus and calculators for everyone to enjoy. These are free links to sites that help children practice their math skills. We also compiled a list of fun, educational calculator games and math resources for kids. Then, we’ll provide a rundown of different types of calculators and what we can learn from using them. In this article, we’ll talk about the calculator and its importance. People use them in engineering, physics, chemistry, and most scientific fields. And though not everyone uses scientific calculators, they are essential for solving problems. For example, we calculate change and measure baking ingredients. When you think about it, we calculate things all the time.
