Here's a fun number cruncher for vacation week. Use just the four digits 1, 9, 9, 7 in that order, with parentheses and any standard math operations, to make all the numbers 0, 1, 2, ... For starters,

    0  =   1*(9-9)*7
    1  =   1^(997)              (to the power of)
    2  =   1+sqrt(9)-(9-7)      (square root)
    3  =   19-9-7

How far can you get? And what's the biggest number you can make?
