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... Last fiddled with by LaurV on 2019-01-10 at 08:58
 2019-01-10, 09:40 #28 henryzz Just call me Henry     "David" Sep 2007 Cambridge (GMT/BST) 2·2,897 Posts 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

For starters
Code:
9-3*3
9/3/3
(9-3)/3
9-3-3
(9+3)/3
