HP 35S Programmable Scientific Calculator (ALG/RPN) With 30KB - 14-Digit LCD(sold individuall)
In the olden days, people used to calculate using objects and items such as sticks, leaves or even beans. However, this will cause misunderstanding and at times, unfairness would happen because it depends on the honesty of the person who is doing the counting. So, to solve this problem, the inventor had come out with abathia, the first handmade calculator made from wooden frame. There are wires in between which are filled with beads. This wooden calculator has been used by most of the merchants and offices for quite some time for normal and easy calculations. However, the functions are quite limited and only suitable for basic calculations.
As the economy and technology becoming more and more advance, inventors had come out with basic calculator for people to perform exact calculation. Some of the functions such as 'plus', 'minus', 'multiply' and 'divide' were then developed. After that, programmable calculators are invented to perform complicated calculations easily. The latest calculator is called scientific calculator. It has been widely used in universities and companies to ease the calculation processes. Looking at the convenience of scientific calculator, Rolf Howarth came out with the idea to develop online scientific calculator in 1996. Square Box Systems Ltd. became the host companies to support this online site since the launching of the software.
