What mathematical operation returns the remainder after division?

What mathematical operation returns the remainder after division?

• A. Division with remainder
• B. Quotient
• C. Modulo
• D. Remainder operation

Answer: (C)

Modulo is the operation that gives the remainder after dividing one number by another. If you divide a by b, you can write a = b·q + r, where q is the quotient and r is the remainder. The modulo result is r—the amount left over after removing as many whole b’s as possible. For example, 14 mod 5 equals 4, since 14 = 5·2 + 4. This is exactly what you’re looking for when you want the remainder. Division with remainder describes doing the division and obtaining both quotient and remainder, but the operation that returns just the leftover piece is modulo.
