## Introduction

The Math Calculator is a fundamental tool that has been an integral part of mathematics for centuries. It enables individuals to perform essential arithmetic operations, including addition, subtraction, multiplication, and division, with ease and precision.

## The Concept of a Math Calculator

A Math Calculator is a device or software application designed to perform basic arithmetic calculations. It simplifies mathematical operations by automating the processes involved in addition, subtraction, multiplication, and division. This tool is indispensable for students, professionals, and anyone needing to perform numerical computations quickly and accurately.

## Formulae for Basic Arithmetic Operations

Addition is the process of combining two or more numbers to obtain their sum. The formula for addition is straightforward:

Sum (S) = A + B

Where:

• S represents the sum of numbers.
• A and B are the numbers being added.

#### Example Calculation:

If we want to add 5 and 7, the calculation would look like this: Sum (S) = 5 + 7 = 12

### Subtraction

Subtraction involves finding the difference between two numbers. The formula for subtraction is:

Difference (D) = A – B

Where:

• D represents the result of subtraction.
• A is the minuend (the number from which subtraction is done).
• B is the subtrahend (the number being subtracted).

#### Example Calculation:

To subtract 9 from 15: Difference (D) = 15 – 9 = 6

### Multiplication

Multiplication is the process of repeated addition and is represented by the following formula:

Product (P) = A * B

Where:

• P is the product of the multiplication.
• A and B are the numbers being multiplied.

#### Example Calculation:

If we want to multiply 4 by 6: Product (P) = 4 * 6 = 24

### Division

Division involves splitting a quantity into equal parts. The formula for division is:

Quotient (Q) = A / B

Where:

• Q represents the quotient obtained from the division.
• A is the dividend (the number being divided).
• B is the divisor (the number by which division is performed).

#### Example Calculation:

To divide 20 by 4: Quotient (Q) = 20 / 4 = 5

## Real-World Use Cases
