**Calculators** are electronic devices which are used to perform calculations which range from arithmetic to complex calculations.

The first **zero calculator** was made in 1980’s by the Solid-State Electronic Company which was pocket sized and became available for the users to use in 1975. The very first version of zero calculator wasn’t that up to the mark and expectations of the users. But with the passage of time and all the new updates, the zero calculator was given all the possible injections to meet the expectations of the users.

According to a research, the calculator was used for performing basic calculations back in 1990 with the percentage of 50 in the whole world. This shows the indication that calculator was one of the best partner for those who had to perform some sort of calculations.

But with the passage of time, calculators diminished to the usage rate of 1% in the whole world and that all because of introducing all the new technologies. For example mobile phone which has built-in calculator.

Let’s forget about all the new technologies and talk about Zero Calculator Design and Working so that you people get to know about why these calculators are still important to most of us.

Finding Zero Calculators online these days is such a difficult task because most of the people are running to provide all the latest technology to the needy. But what about few people who are looking for some old stuff? Will they always be ignored? I guess no, because we are here to assist you in all the possible way to provide you what you need. And zero calculator is one of them. So let’s head towards the input and output of Zero Calculator

**Input:**Zero Calculator contains a keyboard which contains all the numbers (Digital and Arithmetic) operations. In some calculators, there are “00 and 000” for the larger calculations so that you don’t have to get tired all the time when you perform bigger calculations. In the entire new zero calculators, there are several new buttons which can perform multiple function at one time.**Output:**As an output, zero calculator uses LCD as showing the results. In the latest calculators, LED and VFD technology has been used to improve the readability and user experience.**Memory:**All the new calculators in the market have the tendency to store numbers and calculation in their memory. Few of the calculators use memory card to store all the calculation and even whole questions & answers. But most of the examination centers do not allow students to bring along with them because they have a fear of student doing cheating.**Power Source:**Zero calculator uses different power sources to use for instance, solar power, cells, batteries and main electricity. Some of the zero calculators doesn’t have the power off option but there are certain ways to turn off the screen (For example, Doing no operation for a while, closing the lid of calculator etc)
