8-8+8*8/8

Solution: choose any 4 numbers in 3.2.6.9.8.5.7, and calculate 24 by addition, subtraction, multiplication and division?

The building owner
2×6+5+7=24
2×5+8+6=24
3×7+(9-6)=24
3×8×(6-5)=24
3×8×(7-6)=24
3+5+7+9=24
2+6+7+9=24
3×2×8÷2=24
（-3+9）×8÷2=24
……
That's all I've calculated. I've tried my best
I play by hand

There are number cards 2, 1, 6 and 9. Combine them at will and add, subtract, multiply and divide them. The result is 24. How many kinds can you write?

（9-1）/2 *6=24
（2*9+6）*1=24
（2*9+6）/1=24
（9/6*2+1）!=24
（6²/9*1）!=24
（6²/（9*1））!=24
There are still a lot of it

Now there are four rational numbers: - 9, - 6, 2, 7. Can you calculate 24 with three different algorithms?

2 + 7-(-6)-(-9)=24
[7-2+(-9)]×(- 6)=24
(- 9) × 2 -(-6) × 7=24
