Which three primes add up to 58, and which two primes add up to 39?
11 + 13 + 34 = 58, 37 + 2 = 39
In 15, 18, 29, 35, 39, 41, 47, 58, 70, 87, the prime number has (); the composite number has ()
In 15,18,29,35,39,41,47,58,70,87, the prime number is (29,41,47,); the total number is (15,18,35,39,58,70,87)
This is the first answer. I wish you progress!
