There are 10 digits, but for a three digit number the first number cannot be a 0.

Thus: there is a choice of 9 digits for the first (and last digit which must be the same), with

10 choices of digit for the second (middle) digit,

making 9 × 10 = 90 such palindromic numbers.

How many different palindromes are there with 6 digits?

For there to be palindromes, each digit must be replicated. Therefore there are at most three distinct digits.If there are 3 pairs of different digits, then there are 6 palindromes. If there can be more duplicate digits, then there are 27 palindromes.

How many 5 digit palindromes are there?

900 This explains it. A positive integer is a palindrome if it reads the same forward and backwards such as 1287821 and 4554. Determine the number of 5-digit positive integers which are NOT palindromes. We start by counting the total number of 5 digit positive integers. The first digit is between 1 and 9, so we have 9 choices. Each of the other 4 digits can be anything at all (10 choices for each). This gives us 9(10)4 = 90000 five-digit positive integers. Now we need to count the number of 5 digit palindromes. Again, we have 9 choices for the first digit and 10 choices for each of the next two. The tens and units digits however are fixed by our choices so far. Therefore, there are only 900 five-digit palindromes. Therefore, the total number of five-digit positive integers which are not palindromes is 90000-900 = 89100.

Can 100 different digits make 100 multiplied by 100 equal 10000 different three digits palindromes?

Yes. But that is true only if the 100 digits do not include 0. Or, if 0 is included, then you consider "0n0" to be a three digit number. Most people would consider is to be a 2-digit number.


How many different three digit palindromes can you make using only the digits 1and 2?

There are two possible digits for the first and last digit, and two possible digits for the centre digit, making 2 × 2 = 4 possible 3 digit palindromes from the set {1, 2}, namely the set {111, 121, 212, 222}.


Are there more 11 digit or 12 digit palindromic numbers?

There are the same number: any twelve digit palindrome is just an eleven digit palindrome with its central digit repeated. In general, if we are considering numbers of n digits: For even values of n, the number of palindromes is 9 x 10n/2 - 1 For odd values of n, the number of palindromes is 9 x 10(n-1)/2

How many palindromic numbers are there between ten and hundred thousand?

1089.ExplanationA two digit palindrome will have the form AA, with A a digit between 1 and 9 (if A were zero, then this would not be a two digit number). So there are 9 possibilities for A and nine two-digit palindromes.A three digit palindrome will have the form ABA, with A a digit between 1 and 9 (if A were 0, this would not be a three digit number) and B a digit between 0 and 9. So there are 9 possibilities for A and 10 for B. There are thus 9*10=90 three digit palindromes.A four digit palindrome will have the form ABBA, with A a digit between 1 and 9 (if A were 0, this would not be a three digit number) and B a digit between 0 and 9. So there are 9 possibilities for A and 10 for B. There are thus 9*10=90 four digit palindromes.A five digit palindrome will have the form ABBBA, with A a digit between 1 and 9 (if A were 0, this would not be a three digit number) and B and C each a digit between 0 and 9. So there are 9 possibilities for A, 10 for B, and 10 for C. There are thus 9*10*10=900 five digit palindromes.Adding the above, we get a total of 9+90+90+900=1089 palindromes in the range.

How is multiplying a 2-digit number by a 1-digit number the same as multiplying a 3-digit number by a 1-digit number and how is it different?

They are the same because they are both multiplication. They also can be the same if the two digit number times by the one digit number equals a three digit number. They are different because the 3 digits number will obviously produce a higher product.
