You (general you) don't need to post 100 lines, to show us that you know to add and subtract or know how to use Excel.

Haha, now if we use only 8258 to make* 0, 10, 20, 30, +\(\infty\), then we are done...
If possible, only once, no parenthesis...

*technically, as you posted 0 to 10 inclusive, we would only need to make 0, 11, 22, 33, 44...

Actually they can be used to add or subtract 0 to 10 meaning a range of 21 not 11. Can this list be expanded? What can be done with just the last 3 digits?

59 = (8+2)*5+8 + (9/9*3/3)
60 = (8+2)*5+8 + (9/9+3/3)
61 = (8+2)*5+8 + (9-9/3-3)
62 = (8+2)*5+8 + ((9+9/3)/3)
63 = (8+2)*5+8 - (9/9-3-3)
64 = (8+2)*5+8 + (9-9+3+3)
65 = (8+2)*5+8 + (9/9+3+3)
66 = (8+2)*5+8 + (9-9/3/3)
67 = (8+2)*5+8 + (9*9/3/3)
68 = (8+2)*5+8 + (9+9/3/3)

The 5 axn posted was actually -5. Fortunately I checked my results. It is so easy to make a mistake with this puzzle!!

Yep, I tried to generate 5 but didn't really get anything. But since the intent was to do +/-, a -5 is as good as a 5.

Appending a - on the beginning did the trick. Would have been useful in your post.

I might consolidate correct results in the first post at somepoint. I will probably also make a list for the last 4 digits to aid with creating more.

I wasn't sure about the legality of unary - operator. Anywho, I had already dropped the mic. You can't go back and pick it up again
