Mr Bear will calculate every prime number up until the limit that you tell him.
This is Mr. Bear's algorithm for finding prime numbers: Divide your candidate number by every prime number beknown before the candidate itself. For example, in order to determine if candidate number 17 is prime or not, Mr. Bear divides 17 by 2, 3, 5, 7, 11, and 13. Since candidate 17 is not divisible by any of these, 17 is a prime number. How do you calculate prime numbers?
