x \mod aThe modulo operation, represented by 'x \mod a', returns the remainder of the division of x by a. It is a fundamental operation in number theory and computer science, often used to determine if a number is divisible by another, to wrap around values within a certain range, or to perform cyclic operations.
The remainder of 10 divided by 3 is 1.
10 \mod 3 = 115 is exactly divisible by 5, so the remainder is 0.
15 \mod 5 = 0The remainder of 7 divided by 4 is 3.
