##### Solutions:
 1. = 18 + 7 – 5 2.   = {9 x 3 + [7 + 30] - 4} 3.  = 2 – (2 x 36) = 25 - 5 = 27 + 37 – 4 = 2 – 72 = 20 = 67 – 4 = -70 = 63 4. = 9 + (18 ÷ 6) - 2 5.  = [30 + 6/2 – 4] 6.  =121 + 9/3 = 9 + (3) - 2 = [30 + 3 – 4] = 121 + 3 = 10 = [33-4] = 124 = 29 7.  = {48 + [(4 x 3) + 2 – 5] + 3} 8.  = 13 – 8 + 2 = {48 + [12 + 2 – 5] + 3} = 7 = {48 + [9] + 3} = 60
