A modulo calculator is a tool or a function that performs modulo arithmetic, which is the calculation of the remainder when one integer is divided by another. The modulo operator is denoted by the symbol “%”.

**Enter Information**

Enter Information:

The modulo operation calculates the remainder when one integer (the dividend) is divided by another integer (the divisor).

The formula for the modulo operation is:

dividend % divisor = remainder

where the % symbol represents the modulo operator.

For example, 7 % 3 = 1, because 7 divided by 3 is 2 with a remainder of 1.

## Modulo Calculator with Steps

A Modulo Calculator with Steps is an online tool that calculates the remainder when one integer is divided by another using the modulo operation. The modulo operation (represented by the % symbol in most programming languages) returns the remainder of a division operation.

The modulo calculator with steps not only calculates the remainder but also shows the steps involved in the calculation. This can be helpful for users who want to see how the modulo operation works and how the remainder is calculated.

For example, if you want to calculate the remainder when 23 is divided by 5 using the modulo operation, you would enter “23” into the “Dividend” input box and “5” into the “Divisor” input box. Then, click on the “Calculate” or “Modulo” button. The calculator will show the steps involved in the calculation, which would be:

23 divided by 5 = 4 with a remainder of 3

Therefore, the remainder of 23 divided by 5 is 3.

## What Exactly is Modulo?

Modulo, denoted by the % symbol in most programming languages, is a mathematical operation that returns the remainder of a division operation between two integers. It is sometimes referred to as “modulus” or “mod” for short.

The modulo operation works as follows: Given two integers, the first integer is divided by the second integer. The remainder of this division operation is then returned as the result of the modulo operation.

For example, if we take 7 % 3, the result would be 1, because 7 divided by 3 is 2 with a remainder of 1. Similarly, if we take 10 % 2, the result would be 0, because 10 divided by 2 is exactly 5 with no remainder.

Modulo is commonly used in computer programming for a variety of purposes, including:

- Checking if a number is even or odd: An integer is even if it is divisible by 2 with no remainder. Therefore, to check if a number is even, we can use the modulo operation with a divisor of 2. If the remainder is 0, the number is even; otherwise, it is odd.
- Implementing repeating patterns: By taking the modulo of an index variable with the length of a pattern, we can create repeating patterns in loops or other iterative structures.
- Generating random numbers: By taking the modulo of a large number with a smaller number, we can generate a pseudo-random sequence of numbers.

## Modular Arithmetic Calculator

A Modular Arithmetic Calculator is an online tool that performs arithmetic operations on numbers using modular arithmetic. Modular arithmetic is a system of arithmetic for integers where numbers “wrap around” after reaching a certain value called the modulus.

Here are the steps to use a Modular Arithmetic Calculator:

- Open the Modular Arithmetic Calculator in your web browser.
- Enter the first integer into the input box labeled “Number 1”.
- Select the arithmetic operation you want to perform from the drop-down menu labeled “Operation”. The available options are addition, subtraction, multiplication, and division.
- Enter the second integer into the input box labeled “Number 2”.
- Enter the modulus into the input box labeled “Modulus”.
- Click on the “Calculate” or “Compute” button to perform the arithmetic operation using modular arithmetic.
- The calculator will display the result of the operation using modular arithmetic, as well as any intermediate steps involved in the calculation.

For example, if you want to perform the operation (24 + 17) mod 10 using modular arithmetic, you would enter “24” into the “Number 1” input box, select “Addition” from the “Operation” drop-down menu, enter “17” into the “Number 2” input box, and enter “10” into the “Modulus” input box. Then, click on the “Calculate” or “Compute” button. The calculator will display the result as:

(24 + 17) mod 10 = 1

The result of (24 + 17) mod 10 is 1, because the sum of 24 and 17 is 41, and when 41 is divided by 10, the remainder is 1.

## Modulo Calculation Example

Let’s say we want to find the remainder when 21 is divided by 5 using the modulo operator.

We can use the following formula: dividend % divisor = remainder.

So, in this case, the dividend is 21, the divisor is 5, and we want to find the remainder.

We can perform the calculation as follows:

21 % 5 = 1

This means that the remainder when 21 is divided by 5 is 1.

Another example would be if we wanted to find the remainder when 87 is divided by 12 using the modulo operator.

We can use the same formula: dividend % divisor = remainder.

So, in this case, the dividend is 87, the divisor is 12, and we want to find the remainder.

We can perform the calculation as follows:

87 % 12 = 3

This means that the remainder when 87 is divided by 12 is 3.
