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 as reported by me earlier in. 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. Similarly for a number consisting of 4 consecutive digits, the Unique number U4 = 3087.

The minuend is the number from which the subtrahend is subtracted.

The difference is that number.

It reduces the number of digits after the decimal point in the display, rounding the number as appropriate.

81.

No number satisfies all of those conditions.

The minuend is the number from which the subtrahend is subtracted.

18, 27, 36, 45, 54, 63, 72, 81, 90? 1, 10, 19, 28, 37, 46, 55 A-Ha!

1,111,111 since 17 = 1

The subtrahend is subtracted from the minuend
