What do you use when you have many numbers to add, or when you have to compute something? How long will it take you to use your fingers to count numbers in the millions?







One of the challenges for people is doing calculations, especially when there are a lot of things to count or when you run a business. To address this difficulty, a counting machine was invented.





Around 3000 BC, a counting device known as the abacus was developed in China. It’s been used since then and there are even people who still use them in these modern times.
