All calculations are performed locally in your browser. Results are for educational and analytical purposes. For cryptographic applications, ensure you are using the specific modulo definition required by your algorithm.

📋 HOW TO USE — STEP BY STEP

1. Dividend (a): Enter the number to be divided.
2. Divisor (n): Enter the number to divide by (cannot be zero).
3. Calculate: Click "Calculate Modulo" to see the remainder.
4. View Results: See the remainder, quotient, and step-by-step breakdown.

📊 UNDERSTANDING MODULO

Formula: r = a - n × floor(a/n).
Remainder: The amount left over after division.
Negative Numbers: In mathematics, the remainder usually has the same sign as the divisor. In programming (like JS/C), it often has the same sign as the dividend. This tool uses the mathematical definition.

Modulo Arithmetic Formulas

Here are some essential formulas used in modular arithmetic calculator:

  1. Addition Modulo:

(a+b)mod  n=((amod  n)+(bmod  n))mod  n(a + b) \mod n = ((a \mod n) + (b \mod n)) \mod n

  1. Subtraction Modulo:

(a−b)mod  n=((amod  n)−(bmod  n)+n)mod  n(a – b) \mod n = ((a \mod n) – (b \mod n) + n) \mod n

  1. Multiplication Modulo:

(a⋅b)mod  n=((amod  n)⋅(bmod  n))mod  n(a \cdot b) \mod n = ((a \mod n) \cdot (b \mod n)) \mod n

  1. Exponentiation Modulo:

(ab)mod  n=((amod  n)b)mod  n(a^b) \mod n = ((a \mod n)^b) \mod n

  1. Division Modulo (requires modular inverse):

(a/b)mod  n=(a⋅b−1)mod  n(a / b) \mod n = (a \cdot b^{-1}) \mod n
