What is the sum of 4 and 16?

• A. 20
• B. 12
• C. 24
• D. 16

Answer: (A)

Adding these two numbers means combining quantities. Start at 16 and move forward four steps: 17, 18, 19, 20. You land on 20, so the sum is 20. The other options don’t reflect adding four: 12 comes from subtracting four from sixteen, 24 comes from adding eight (or doubling in some cases), and 16 is just the original number without adding the four.
