There are 10 palindromes divisible by 9 between 1000 and 9999.
An infinite number.
9 of them.
there are 90 palindromes in 100 to 1000 As; 10 palindromes in each 100 and upto 1000, there are 9 hundreds.Therefore; 9 into 10 is equal to 90
There are infinitely many multiples of 9 and it is not possible to add them all.
think I suppost to know.
They are the infinitely many multiples of 990.
