1001, 1111, 1221, 1331, 1441, 1551, 1661, 1771, 1881, 1991
the numbers that when turned around (1661 turned aroung is 1661) and are still the same number~ :) hoped this helped

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 = 119Actual number of primes between 1000 and 2000 should be a little above 119(in the range [140, 160] i think)
1000
Ten. They are all of the form 1xx1 where x can take the values 0,1,2,...,9
Three numbers.
2000.The smallest four-digit number there can be is 1000. So, add 1000 and 1000 to get 2000, then least sum you can get when adding two four-digit numbers.
All numbers between 1000 and 2000, or anywhere else, can be expressed as a power of another number.

They are 1024, 1125 and 1372.
1000 to 2999 inclusive so 2000 numbers.
1000+1000 1000x2
1000
The two thousand numbers either side of 1999 are 1000 and 2000. The difference between 1999 and these numbers are 999 and 1 respectively. Clearly the second is nearer.
999 (whole) numbers. THere are the same number whether they are counted in ascending, descending or other order.
M-MM
3000 It is 2000 more than 1000 and 2000 less than 5000 To find a halfway point (which is also the average), add the numbers together and divide by 2.
