386: Start off by understanding that 387 is a multiple of 9, leaving you with 3, 10, 9 and 8 to find 43. You can get 24 with 3 and 8, and luckily it sums with 19 to get 43. 😎 (Took me way longer than 30 seconds though)
1. (3x8+9+10)x9-1=386 or (8-3)x9-1=44x9-10=386 or (3x9+9)x(1+10) 2. 100x(4+6)-8+7=999 or (100+(4x6))x8+7=999 3.. (100+2-(4x5))x7=574 or (100-(2x(4+5))x7=574 or 100/5+25-4=41x2x7=574 4. (75x4-5x9)x2=510 or (75+1+9)x(2+4)=510 or (1+2)x9+75=102x5=510

Surprised no one went for 111 * 9 on the 999. Turns out it was a fairly elegant solution of multiplying two sums (100 + 7 + 4 and 6 + 3).
Three years later ...
386=(3*8)+10+9 for 43, *9 -1
Yh took me longer than 30 but got there in the end
(10+1)×3=33
33+9=42
42×9=378
378+8=386
3:50 "greg found the only way that lead to a dead end" haha that's a roast
1. (3x8+9+10)x9-1=386 or (8-3)x9-1=44x9-10=386 or (3x9+9)x(1+10)
2. 100x(4+6)-8+7=999 or (100+(4x6))x8+7=999
3.. (100+2-(4x5))x7=574 or (100-(2x(4+5))x7=574 or 100/5+25-4=41x2x7=574
4. (75x4-5x9)x2=510 or (75+1+9)x(2+4)=510 or (1+2)x9+75=102x5=510
Highest number target ever
Also 574=(100+2*7)*5 +4
510:
9 - 2 = 7
75 * 7 = 525
4 - 1 = 3
5 * 3 = 15
525 - 15 = 510
75 + 9 + 1 = 85
4 + 2 = 6
85 * 6 = 510
4 - 1 = 3
9 * 3 = 27
75 + 27 = 102
102 * 5 = 510
386.
In time I got 384
(9-3)×8×(9-1)=384
Had to go to the comments for 386😢
574
7*2=14
100+ 14
114*5= 570
570+4= 574
999: 100 + 8 + 3 = 111. 7 + 6 - 4 = 9. 9 x 111 = 999.
386 solution
(8 x 3 + 10 + 9) x 9 - 1
8-3 = 5
5×9= 45
45-1=44
44×9=396
396-10=386
386:
8 - 3 = 5
9 * 5 = 45
45 - 1 = 44
44 * 9 = 396
396 - 10 = 386
3 + 1 = 4
9 * 4 = 36
36 + 8 = 44
44 * 9 = 396
396 - 10 = 386
10 + 1 = 11
11 * 3 = 33
33 + 9 = 42
42 * 9 = 378
378 + 8 = 386
574=7×(100+2-4×5)
510=(75+9+1)×(4+2)
574
(100+7+2)×5+25+4=574
(75 + 9 + 1) × (4 + 2) = 85 × 6 = 510
10+1 = 11X3 = 33+9 = 42X9 = 378+8 = 386
8X3 = 24+10+9 = 43X9 = 387-1 = 386
100÷4 = 25 7+6 = 13X25 = 325+3 = 333X3 = 999
8-7 = 1 4+6 = 10X100 = 1,000-1 = 999
100-25 = 75+5+2 = 82X7 = 574
100÷5 = 20-4 = 16+25 = 41 7X2 = 14X41 = 574

386=9×(3×8+10+9)-1
I got admiralty before Peter buzzed.
[(100 + 7 + 2) × 5] + 25 + 4 = 545 + 29 = 574
OR
{[100 + (7 × 2)] × 5} + 4 = {114 × 5} + 4 = 574
(100 + 8 + 3) × (7 + 6 - 4) = 111 × 9 = 999
OR
(100 + 7 + 4) × (6 + 3) = 111 × 9 = 999
{[(8 × 3) + 10 + 9] × 9} - 1 = {43 × 9} - 1 = 386
