Introduction to Modulo Operation

The modulo operation, symbolized as "mod", finds the remainder of division between two numbers. For instance, "5 mod 3" evaluates to 2, as 5 divided by 3 leaves a remainder of 2.

Understanding the Modulo Calculator

This tool simplifies finding the remainder of a division operation. Enter the dividend and divisor to calculate the modulo.

Formula and Calculation

The modulo operation is defined by the formula:

\[ a \mod n = r \]

where \( a \) is the dividend, \( n \) is the divisor, and \( r \) is the remainder.

Practical Applications

Modulo operations are crucial in computer science, mathematics, and various everyday scenarios.
