29, 32, 35, 38, 70, 73, 76, 77, 100 and 1000.

All the numerals must be used in the given order (each just once) and without turning upside down.

I used [brackets] as the symbol for root.

I get all of them except the answer 29... please explain. It would end up being -1+3 + (3^6) which is 2 + 729 = 731 The only way it would work if is 2 is added to 27. To get 27 the multiples are 3x3x3 and I can't figure that out with 9 and 6.

You forgot a root:

-1 + root(9) + root[root(9)^6]

=-1 + 3 + root[3^6]

=-1 + 3 + 3^3

=-1 + 3 + 27

=29

For 32 there is another way to do it:

-1+[9]x9+6=32

For 38:

19/[9]/6=19x6/[9]=38,

actualy is the same,just 1 step before the shown equation.

another solution for 76:

91 - (9+6) = 76

91 - 15

and for 35:

[[9]6] + 9 - 1 = 35

[3^6] + 9 - 1

3^3 + 9 - 1

27 + 9 - 1 = 35

[3^6] + 9 - 1

3^3 + 9 - 1

27 + 9 - 1 = 35

numbers need to be in 1996 order....
