What is the smallest digits palindrome that is the sum of two 3 digit palindromes?
The smallest digit palindrome that is the sum of two 3-digit palindromes is 121. This is achieved by adding the two 3-digit palindromes 101 and 20, both of which are palindromic. Therefore, 101 + 101 = 202, but if we consider a valid case with two different palindromes, we can use 111 and 110, which gives us 221, the next smallest palindrome. However, the smallest individual palindrome formed by the sum of any two 3-digit palindromes remains 121.
How many positive two digit palindromes exist?
There are nine two-digit palindromes: 11, 22, 33, 44, 55, 66, 77, 88 and 99.
What digits are always the same in a 4-digit palindrome?
None. 1221 and 3443 are both 4-digit palindromes but no digit has remained the same between the two. First and fourth, second and third.
What is the smallest 4 digit palindrome that is the sum of 2 3 digitit palindrome?
The smallest 4-digit palindrome is 1001. To find if it can be expressed as the sum of two 3-digit palindromes, consider the smallest 3-digit palindromes, which are 101, 111, 121, etc. The combination of 101 and 900 (another 3-digit palindrome) gives 1001, making 1001 the sum of two 3-digit palindromes. Thus, the answer is 1001.
What two-digit prime number has the sum of its digits that is not 7 but is a multiple of 7?
No two digit prime number exists that is a multiple of 7. All two digit numbers that are multiples of 7 are compositenumbers.

What is the product of the largest single-digit prime number and the largest two-digit prime numbers?
679 is the product of the largest single-digit prime number and the largest two-digit prime number.
What is the smallest two-digit prime number?
11 is the smallest two-digit prime number.

How many 4 digit palindromes are multiples of 9?
Nine. The sum of the digits must be a multiple of 9; because of the repeated digits, this is only possible if the first two digits add up to 9.
