480+105÷(101-80)+12×19

480+105÷21+12×19

480+5+228 =713

1385+4×[217+508÷(101-99)]-12×12

1385+4×[217+508÷2]-12×12

1385+4×[217+254]-12×12

1385+4×471-12×12

1385+1884-144 =3125

(999+121)×4+2×[(789-19)×(36÷18)]÷(440÷22)+0×999

1120×4+2×[770×2]÷20+0×999

1120×4+2×1540÷20+0×999

4480+ 3080÷20+0

4480+154+0 =4634
