## Simple Online Calculator

If you often perform mathematical calculations, you know how difficult and time-consuming they can be. In order to carry out simple arithmetic operations, it is necessary to remember the associative and commutative laws of addition and multiplication, as well as the rules of long division and other specific rules.

However, with the use of modern IT technologies, this process can be significantly simplified. The Internet, where information is accessible anytime and anywhere, has made online calculators an indispensable tool for users. These calculators can quickly and accurately calculate various quantities without the need for complex formulas, providing a convenient and free service.

## What is an online calculator?

An online math calculator is a web-based application that allows users to perform mathematical calculations directly in their web browser. It is developed using web technologies such as HTML, CSS, and JavaScript, which ensure that the calculator is accessible on all devices, regardless of the operating system or platform. These technologies also ensure the speed of calculations and the interactivity of the results.

### Classification

Online calculators are divided into 2 main types:

- Basic calculators are ordinary calculators that perform various calculations such as addition, subtraction, multiplication, division, exponentiation, root extraction, etc. They are useful for everyday tasks such as calculating the cost of products or the distance between two points.
- Specialized calculators are calculators designed to perform specific calculations, such as calculating the monthly mortgage payment, loan interest, VAT amount, deposit yield, etc.

### Advantages of online payments

Online calculators have a number of useful advantages:

- Reduce the time spent on solving problems;
- Help you avoid mistakes;
- Can be used anywhere and anytime.

## How to use it

The math calculator online is easy to use. To do this you need:

- Open website;
- Enter the required data;
- Select a mathematical operation;
- Press the "equals" button.

### Usage example

Suppose you need to calculate the area of a square with a side of 175 inches. As we know, the required parameter is calculated by the formula S = a × a = a², where S is the area, a is the side. Enter the number 175 into the calculator, click the "power of number" button and select the number 2. After pressing the "equals" symbol, the calculator will calculate the area of the square, which will be equal to 30,625 square inches.
