{[(12+6):3+43]:7+20}:3×124-1000= [(18 : 3 + 43) : 7 + 20] : 3 x 124 - 1000 = (49 : 7 + 20) : 3 x 124 - 1000 = 27 : 3 x 124 - 1000 = 9 x 124 - 1000 = 116

(178×36):4-[(260:4-2):7+47]:8+348:4= 6408 : 4 - (63 : 7 + 47) : 8 + 87 = 1602 - 56 : 8 + 87 = 1602 - 7 + 87 = 1682

[76-(6×6+8×9):4]:7+[82-(7×5+6×5):5]= [76 - (36 + 72) / 4] / 7 + [82 - (35 + 30) : 5] = (76 - 108 / 4) / 7 + (82 - 65 / 5) = (76 - 27) / 7 + (82 - 13) = 49 / 7 + 69 = 7 + 69 = 76
