Which operator is used to find the remainder in division?

The correct answer is modulo. The modulo operator, often represented as "mod," is specifically designed to find the remainder resulting from the division of one number by another. For instance, when dividing 10 by 3, the operation gives a quotient of 3 and a remainder of 1. The modulo operation directly yields this remainder, allowing for various applications in programming, mathematics, and computer science.

In contrast, the other operations mentioned serve different purposes: the plus operator is used for addition, the minus operator is used for subtraction, and the divide operator is used to determine the quotient in division. None of these options can accurately represent the remainder from division, which is the unique function of the modulo operator. This makes the modulo operator essential for scenarios that require knowledge of division's remainder, such as in calculations related to cycles, checksums, and number theory.
