500-[(16×18-192:f):7+14×5+10]:4×7+9=299

500-[(288-192:f):7+70+10]:4·7=299-9

[(288-192:f):7+70+10]:4·7=500-290

[(288-192:f):7+70+10]:4·7=210

[(288-192:f):7+70+10]:4=210:7

[(288-192:f):7+70+10]:4=30

(288-192:f):7+70+10=30·4

(288-192:f):7=120-80

(288-192:f):7=40

288-192:f=40·7

192:f=288-280

192:f=8=>f=192:8=>f=24
