When you divide a number 'a' by 'b', it can be expressed as 'a mod b' which is the remainder. This is also called as the modulus. Use this mod / modulo calculator to perform the mod operation and find the remainder of the division with ease.

An operation used to find the remainder of the division operation is called as the modulo (Mod operation). In mathematics, the result of the modulo operation is the remainder of the Euclidean division. Some mod operations can be factored or expanded similar to other mathematical operations. This may be useful in cryptography proofs, such as the Diffie-Hellman key exchange. But the common pitfall in mod operation is that when the result of a modulo operation has the sign of the dividend, it can lead to surprising mistakes. Just enter the number a and b, this **Mod / Modulo calculator** will update you the mod value of (a%b) within the fractions of seconds.
