Closest I can't get is 816 (1 away):

50 + (3 /3) =51

25 -10 + 1 = 16

51 * 16 = 816

I checked a solver 816 is the closest.

Solution:

((50 - 8) * (10 +9) ) - 7 + 6

Been a week so new numbers:

Always interesting to see other ways of solving a problem.

I derived the target by: (3 + 7) * 10 * 10 = 1000 - 25 - 8 = 967
