## Big Number Calculator

A Big Number Calculator is a tool used to perform calculations with extremely large numbers that exceed the capacity of standard calculators or computer arithmetic. It allows for precise arithmetic operations, including addition, subtraction, multiplication, and division, with numbers of virtually unlimited size.

### Formula

The formula for performing calculations with big numbers depends on the specific operation being performed.

### Example

For example, when adding or subtracting big numbers, the digits are aligned and added or subtracted column by column. When multiplying big numbers, a process similar to long multiplication is used. Similarly, division involves a process similar to long division.

Big Number Calculators are essential for handling computations involving large numbers encountered in various fields, such as cryptography, scientific research, and computer algorithms.
