All numbers greater than one in that range can be co-prime. 4 and 9 are co-prime.
The sum of a positive integer and a negative integer is positive when the positive integer is greater. For example: 9 + (-5) = 4 In this case, the positive integer 9 is greater than the negative integer 5. Therefore, the sum is positive.

5 is an integer and it is greater than 4, but of course so is 6,7,8,9,10,...and I could go on forever!
40/4=10 60/4=15 Then the second prime are between 10 and 15, two prime numbers: 11 and 13 The prime number is between 44 and 52 : 47

The algorithm is fairly straightforward. For any integer i greater than or equal to zero:i is non-prime if i is less than 2.otherwise, i is prime if i is 2.otherwise, i is non-prime if i is greater than 2 but is divisible by 2.otherwise, i is non-prime if it has any prime factors less than or equal to its square root.otherwise, i is prime.Step 4 is easier to implement by testing all odd divisors from 3 to the square root of i.
