Sagot :
The first four prime numbers are: 2, 3, 5, and 7
Add:
2 + 3 + 5 + 7 = 17 (which is also a prime number)
ANSWER: The sum of the first four prime numbers is 17.
Note: 1 is not a prime number because, by definition, a prime number is a number greater than 1 that has no other positive integers other than itself and 1. Therefore, it has EXACTLY TWO positive divisors.

**NOTE: Integers greater than one are called a prime number if its only positive divisors (factors) are one and itself. Therefore, 1 isn't a prime number and you must remember that :) . **
