Final answer:
The operation 18 mod 3 calculates the remainder when dividing 18 by 3. Since 18 is evenly divisible by 3 with no remainder, the output value of 18 mod 3 is 0.
Step-by-step explanation:
The mathematical operation modulus (often abbreviated as mod) calculates the remainder of the division of two numbers. In the question 18 mod 3, we're looking for the remainder when 18 is divided by 3. To solve this, we can follow these steps:
\\
- \\
- Divide 18 by 3.
- \\
- Find the quotient of the division (the whole number result).
- \\
- Look for any remainder. If there's no remainder, the result of 18 mod 3 will be 0.
- \\
\\
In this case, 18 divided by 3 is exactly 6, with no remainder. So, 18 mod 3 is 0.
\\
Therefore, the correct answer is D. 0.
