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:

$$a\mathrm{mod}n=r$$

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.
