276 = (8-2)*5*8+9*(9+3)/3

278 = (8-2)*5+8+9*9*3-3
279 = -(8+2-5*8)*9 + L3D[9]
280 = 8+2*(5+8)+9*9*3+3

282 = (8+2)*5-8+9*9*3-3
283 = (8*2)*(5+8)+9*9-3-3

21 = -9+9*3+3
24 = 9*9/3-3
30 = 9*9/3+3
33 = 9+9*3-3
36 = 9*(9+3)/3
39 = 9+9*3+3

Also this:

280 = 8*(2*(5+8)+9) {+/- extension}

And this:

288 = (8-(2-5)*8)*9 {+/- extension}

ETA:

294 = (8-2)*(5*8+9) {+/- extension}

300 = (-8+2+5*8)*9 + L3D[-6]
306: 302 to 310 = (-8+2+5*8)*9 + L3D[-4 to 4]

Even better:

304: 299 to 317 = 8*(-2+5*8) + L4D[-13 to 13]

This one solves a lot of multiples of 80:
320 = 8*2*5*(8-L4D[4])

And multiples of 50:
350 = (8+2)*5*(8-L4D[1])

352: 350 to 356 = 8*2*(5+8+9) + L3D[-3 to 4]

Using only division:

160 = 8/(2/5/(8/(9/(9/(3/3)))))

It doesn't solve anything extra.

Some more divisions

1440 = 8/(2/5/8/(9/(9/3/3)))
12960 = 8/(2/5/8/9/(9/(3/3)))
116640 = 8/(2/5/8/9/9/3/3)

I am struggling to find results around this sort of size.
358 = -8+2+5*8+9*(9+3)*3

Default A whole bunch of 357s

357 = 8-2+5*8*9-(9-(3-3))
357 = 8-2+5*8*9-(9+3)+3
357 = 8-2+5*8*9-(9+3-3)
357 = 8-2+5*8*9-(9-3)-3
357 = 8-2+5*8*9-(9-3+3)
357 = 8-2+5*8*9-9*3/3
357 = 8-2+5*8*9-9/(3/3)
357 = 8-2+5*8*9-9/3*3

So many ways to generate 9 with those last three digits.

How didn't I spot that trivial 5*8*9=360?
