The question requires finding the total value when the first six prime numbers are added together.
A prime number is a whole number greater than 1 whose only factors are 1 and itself. Remember that 1 is not a prime number.
The sequence starts with 2, which is the only even prime number.
The first six prime numbers in ascending order are:
Add the identified prime numbers to get the final sum:
$ \text{Sum} = 2 + 3 + 5 + 7 + 11 + 13 $
Performing the addition:
$ 2 + 3 = 5 $
$ 5 + 5 = 10 $
$ 10 + 7 = 17 $
$ 17 + 11 = 28 $
$ 28 + 13 = 41 $
Thus, the sum equals 41.
