Ans: 98765 - 56789 = 41976
Explanation ~~~
If a number An consisting of n consecutive digits in ascending order is subtracted from the number An'obtained by reversing the digits of An, then the difference is always a constant. This constant is termed as the Unique number Un.
For example, a 3-digit number 345 if subtracted from its reverse 543, yields a difference of 198. Thus U3 = 198.
Another 3-digit number, say, 678 if subtracted from its reverse 876 will also yield the same difference, that is, 198.
Thus for any number consisting of 3 consecutive digits, the Unique number U3 is always 198.
if u have any doubt plz comment and mark brainliast thanks
