What is the sum of the first five prime numbers?

• A. 25
• B. 28
• C. 30
• D. 35

Answer: (B)

To find the sum of the first five prime numbers, we first identify what these prime numbers are. The first five prime numbers are 2, 3, 5, 7, and 11. A prime number is defined as a natural number greater than 1 that cannot be formed by multiplying two smaller natural numbers, meaning it has only two distinct positive divisors: 1 and itself. Now, let's calculate the sum: - Start with 2 - Add 3: 2 + 3 = 5 - Add 5: 5 + 5 = 10 - Add 7: 10 + 7 = 17 - Add 11: 17 + 11 = 28 Thus, the sum of the first five prime numbers is 28. This aligns with one of the choices, confirming that it is indeed the correct answer.
