# Which of these numbers add up to 1000 265 160 312 123 75 189 200 98 146 250?

There are two solutions:

1000 = 265 + 123 + 75 + 189 + 98 + 250,

and

1000 = 265 + 312 + 75 + 98 + 250.

### What are the prime numbers between 1000 and 2000?

Do a search on Google, for "prime numbers" table, or "prime numbers" list, and you will surely find something. I cannot tell precisely without looking up a table or doing some longish calculus but as a gross estimatation there should be about this many prime numbers between 1000 and 2000: 2000 / ln(2000) - 1000 / ln(1000) =~ 263 - 144 = 119 Actual number of primes between 1000 and 2000 should be a little…
