168 prime numbers exist between 1-1000.
The work is actually unrelated to math, so I won't bother posting the explanation. However, I can give some detail as to how I did it. If you know how to program, you can set up a simple for loop for all numbers 1-1000, and have a check function that checks if the number is prime or not.
