36
The number is 36.
The sum of any two-digit number and the number formed by reversing the digits is always divisible by 11.Why?The algebraic proof is as follows:(10x+y) + (10y+x) = 11x + 11y = 11(x+y)
It is greater because with more digits the greater the value of the number will be.
which is greater, whole number with 5 digits or the whole number with 6 digits?
It is easiest to explain with an example. Suppose you have a number 4627. Then the number obtained by reversing [the order of] its digits is 7264. The difference between them is the bigger number minus the smaller number. So here it would be 7264 - 4627 = 2637.

No, reversing the order of the digits of a two-digit prime number does not always result in a prime number.
It is greater because with more digits the greater the value of the number will be.
which is greater, whole number with 5 digits or the whole number with 6 digits?
The least whole number with 6 digits is greater because it has more digits than 5 digits.
It is easiest to explain with an example. Suppose you have a number 4627. Then the number obtained by reversing [the order of] its digits is 7264. The difference between them is the bigger number minus the smaller number. So here it would be 7264 - 4627 = 2637.
73 7-3 = 4 73 is prime and 37 is prime.
Integers of 6 digits are normally greater than integers of 5 digits
18 of them.
