Introduction

A calculator is an electronic device used for making mathematical calculations. It was invented by Blaise Pascal. Most calculators add, subtract, multiply, and divide, but some contain square root symbols. It has an input device name as a keyboard. Visual display shows the output.

Definition of a calculator

It is an electronic or mechanical device that performs simple calculations automatically and can be controlled by the user’s keyboard or a calculator. Types of calculator scientific calculator:

These calculators are used in both educational and professional fields as they are designed in a desktop or hand-held manner.

Graphic calculator:

These are used to perform graph calculations and trigonometry.it is a mathematical tool that requires a lot of graphs, like calculus.

Financial calculators:

These computers are designed to solve financial problems like record keeping.

Basic calculator:

These are also called pocket calculators as they are small. These are the least expensive calculators.

 Advantages

 Quickly and Efficiently:

 The calculator allows everyone to solve problems quickly and efficiently.

.Demoralization:

It does not discourage the topics. It always entertains people to solve their sums easily and quickly.

Capacity:

It can give correct and accurate answers better than human beings.

Cheap and Affordable:

Everyone can buy it as it is affordable and costs low.

Time-saving gadgets:

They perform the task in a fraction of a second as they are time-saving gadgets.

Disadvantages

Limited battery:

As we know, calculators work on batteries or cells with little battery life. They cannot work for extended periods.

Dependency:

We should not depend on calculators as they solve operations instantly.

Cheating:

It is one of the most significant disadvantages of a calculator, which allows you to store information like notes and formulas. This provides an opportunity to store unofficial information to cheat.

High cost:

Compared to digital calculators, scientific, graphic, and financial calculators are too costly as they are advanced in nature.

Conclusion

This topic covers information about the calculator for exact real computation numbers and implementation. A single-user interface has been created to calculate the value to get correct and accurate answers.
