There are 99 palindromic numbers between 10 and 1000: 11, 22, 33, 44, 55, 66, 77, 88, 99, 101, 111, 121, 131, 141, 151, 161, 171, 181, 191, 202, 212, 222, 232, 242, 252, 262, 272, 282, 292, 303, 313, 323, 333, 343, 353, 363, 373, 383, 393, 404, 414, 424, 434, 444, 454, 464, 474, 484, 494, 505, 515, 525, 535, 545, 555, 565, 575, 585, 595, 606, 616, 626, 636, 646, 656, 666, 676, 686, 696, 707, 717, 727, 737, 747, 757, 767, 777, 787, 797, 808, 818, 828, 838, 848, 858, 868, 878, 888, 898, 909, 919, 929, 939, 949, 959, 969, 979, 989, 999.

Answer 2

Well, honey, there are 90 palindromic numbers between 10 and 1000. You see, a palindromic number reads the same forwards and backwards, just like my attitude - always on point! So, next time you need a palindrome fix, just remember there are 90 of 'em waiting for you between 10 and 1000.

Answer 3

A palindromic number reads the same backward as forward. To find the number of palindromic numbers between 10 and 1000, we consider the different cases based on the number of digits. For two-digit palindromic numbers, there are 9 possibilities (11, 22, ..., 99). For three-digit palindromic numbers, there are 90 possibilities (101, 111, ..., 191, 202, ..., 292, ..., 909, 919, ..., 999). Therefore, the total number of palindromic numbers between 10 and 1000 is 9 + 90 = 99.
