"A puzzle"
 
   A puzzle.
Let us create a number consisting of the numbers 1-60.

123456789101112131415 ... 57585960.

What is the largest number that can be left if exactly 100 digits are removed and the remaining digits are in no way rearranged?

   Hi Jman,

So longs as the 100 digits to be removed need not be consecutive, the largest number that can be left is 99,999,785,960.
