Which operator should be used to determine if a number is evenly divisible by 5?

The modulus operator (%) is used to determine the remainder of a division operation. When checking if a number is evenly divisible by another number, you would divide the number by that divisor and look at the remainder. If the remainder is 0, it means the number is evenly divisible.

For example, if you want to check if 20 is evenly divisible by 5, you would perform the operation 20 % 5. Since the remainder is 0, it confirms that 20 is indeed evenly divisible by 5. In contrast, the other operators do not serve this purpose: addition (+) accumulates values, subtraction (-) reduces them, and division (/) provides a quotient, but only the modulus operator gives you the necessary information about divisibility by showing the remainder.
