9999 is the 4-digit number and 999 is the 3-digit number.

The lowest positive 4-digit number is 1000

The largest 4 digit number in base 8 is 77778 (= 409510).

4082 Since the tens digit is 2 times the thousand digit, it must be an even digit. So it can be 8, 6, 4, or 2. But, the thousands digit is 4 greater than the hundred digit. So that the hundred digit must be 0, the thousands digit must be 4, the hundreds digit must be 8, and the ones digit must be 2.

This is not true. Think about any 4 digit multiplied by 1. This remains a 4 digit. In the case of any 4 digit under 5000, multiplied by two would also be a 4 digit number

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.

The largest possible four-digit number is 9999.In math, a palindrome is a number that reads the same forwards and backwards.For example: 121 is a palindrome because it reads the same from front to back, and from back to front.If you want to find the greatest 4-digit palindrome:We have 4 digits to create, I will represent them by using underscores._ _ _ _For each digit, we can use any number 0 - 9.For this number to be the greatest, we know that we have to use a 9 in the first digit.9 _ _ _And, since we want this number to be a palindrome, we have to use the same digit in the 4th slot.9 _ _ 9Only 2 slots left to fill now, and it will be very easy.Again, we must use any digit 0 - 9 to fill our last 2 slots.AND this number must be the same to make our number a palindrome.We can use process of elimination to help us fill in these last 2 slots.If we put a 0 in those slots, 9009. Are there any 4 digit palindromes larger than this?Well, yes. 9119. again... any 4 digit palindromes larger?Again yes. 9229as you can see, we find larger 4 digit palindromes until...9999Once we hit 9999 we've exhausted all possible answers for a 4 digit palindrome.and that will be your answer.

It doesn't always. It's true only if the 4-digit numbers are mirror images of each other.

If you realize that a 4 digit palindrome is basically a two digit number followed by it's own reverse, you can re-phrase this question as 'how many two digit numbers are there?' Which would then mean that (if you're considering zeros as digits without a non-zero leading term) there would be a 4 digit palindrome 0000 for the two digit 00; a four digit 0110 for the two digit 01; 0220, 02; etc etc. So the number of four digit palindromes would be the same as the quantity of whole numbers from 00 to 99. So I believe the total answer to your question would be 100.

If your asking in a digit it's called a 4 digit number and it is the smallest 4 digit number

4224

do you mean mean dates or years? If we use 2 digit month and day and 4 digit year jan 2, 2010 01 02 2010 2112 is the next palindrome year

The number '4' can be considered a palindrome because it is read the same whether forward or backward. It can become another palindrome when it is considered as 2x2.
