It does not test if n is less than 2, and there are no primes less than 2; It tests every number between 2 and n**0.5 including all even and all odd numbers. Since every number greater than 2 that is divisible by 2 is not prime, we can speed it up a little by only testing odd numbers greater than 2. So:

Bertrand's postulate (actually a theorem) states that if n > 3 is an integer, then there always exists at least one prime number p with n < p < 2n − 2. A weaker but more elegant formulation is: for every n > 1 there is always at least one prime p such that n < p < 2n.Step 1. Make sure it is a counting number greater than \hspace {0.2em} 1 \hspace {0.2em} 1. And that it isn't a perfect square. Or else, the number cannot be prime. \hspace {0.2em} 97 \hspace {0.2em} 97 passes this test. Step 2. Think of the largest number whose square is less than the given number.
Step 1: First create a list of numbers from 2 to 100 as shown above. We leave the number 1 because all prime numbers are more than 1. Step 2: We start from the first number 2 in the list. We cross out every number which is a multiple of 2 except 2. For example, we cross 4, 6, 8, 10, 12, 14, 16, and so on up to 100.
