The largest number you can write using Roman numerals without an overline at any symbol is 3999 (MMMCMXCIX), and the largest possible number is 3999999 (MMMCMXCIXCMXCIX, with an overline over the first nine letters.
The largest 4-digit number possible using the digits 4, 1, 9, and 2 is 9412. To form this number, arrange the digits in descending order, starting with the highest digit. Thus, the order is 9, followed by 4, then 2, and finally 1.
874321 is the largest number made from all these digits.

99 is the largest two digit number. If I can use the digits anyway I want, then 9 to the 9th power is larger
use the numbers 5,6,7,8 to write an equation with the largest possible equation
There is no largest number. You can just keep going.

24 is equal to 8 x 3 (the largest possible power of 2), making 23 * 3.
Use the following algorithm (written in pseudocode). Let largest be the lowest possible real number. Let smallest be the greatest possible real number. Repeat while there is input... { Read real number r from input. If r is greater than largest then let largest be r. If r is less than smallest then let smallest be r. } End repeat. Let range be largest minus smallest. Output range.
99,999,998
That would be 999.
