To find the sum of the first ten prime numbers, you first have to find what the first 10 prime numbers are. They are 2, 3, 5, 7, 11, 13, 17, 19, 23, and 29. Added together they equal 129.
To find the first ten prime numbers, you can start with the number 2 and then iteratively check if each subsequent number is divisible by any of the prime numbers found so far.
