100 - 2 - 2 = 96
96 * 9 = 864
864 - (8-3) = 859

Toughie.....

I pick the numbers at random (more or less) but I can see a straightforward solution.

Hobart

(100 +9) * 8 = 872

(2+2) * 3 = 12

872 - 12 = 860

50 5 9 4 2 6

Target 677

50 5 9 4 2 6

Target 677

50 + 2 = 52
52 * (9 + 4) = 676
676 + (6 - 5) = 677


10 25 8 6 3 1

492

Hobart

(3 - 1) * 10 = 20 * 25 = 500 - 8 = 492

9 9 8 6 10 7

Target 901

6*10*(7+8) = 900
9/9 = 1

I'm sure someone posted up the rules for this ...

6 at random from a selection that has 2 each of all the numbers from 1 to 10 (both randomly distributed amongst two sets of two rows so you can choose somewhat strategically) and the "big numbers" of 25, 50, 75 and 100.

7 4 13 40 15 9

Target: 364

13, 15 and 40 aren't possible choices.

(9*40)+4 = 364 though.

13 * 4 * 7 = 394

or
75 - (2 * 4) = 67
67 * 5 = 335
335 + 2 = 337

Okay I think I have it this time:

6 7 9 5 4 25

Target: 312
