what is thecdifference between the sum of the first three 3-digit prime numbers with the sum of the last two 3-digit prime numbers
The last 3-digit primes are:
983 + 991 +997=2,971
The first 3-digit primes are:
101 + 103 + 107=311 , so the difference between the sums of last and the first three primes is:
2,971 - 311=2,660
