203 - 135 ÷ 9 = 203 - 15 = 188

28 + 120 × 8 = 28 + 960 = 988

97 - 12 × 6 + 43 = 97 - 72 + 43 = 25 + 43 = 68

26 × 4 - 125 ÷ 5 = 104 - 25 = 79

42 + 6 × 12 - 4 = 42 + 72 - 4 = 110

240 ÷ 20 - 5 = 12 - 5 = 7

37 - 15 + 8 - 14 = 22 + 8 -14 = 30 - 14 = 16

(124 - 85)×12 ÷ 26 = 39 × 12 ÷ 26 = 18

(75 + 240) ÷ (20 -5) = 315 ÷ 15 = 21
