The sum of the first five prime numbers is 28.
Let's break down how we arrive at this answer.
Understanding Prime Numbers
A prime number is a whole number greater than 1 that has only two divisors: 1 and itself. It is not divisible by any other number without leaving a remainder.
Identifying the First Five Prime Numbers
The first few prime numbers are:
- 2 (The only even prime number)
- 3
- 5
- 7
- 11
Note that 1 is not a prime number because it only has one divisor (itself).
Calculating the Sum
To find the sum of the first five prime numbers, we simply add them together:
2 + 3 + 5 + 7 + 11 = 28
Summary
Therefore, the sum of the first five prime numbers (2, 3, 5, 7, and 11) is 28.
