Explicație pas cu pas:
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=120-10-70 -> Aplicam metoda mersului invers.
(288-192:F):7=40
288-192:F=40×7
192:F=288-280
192:F=8
F=192:8
F=24 -> Numărul
