a) 32 ÷ 8 + 49 ÷ 7 - 2 x 4 = 4 + 7 - 8 = 3
b) 81 ÷ 9 + 36 ÷ 3 - 8 ÷ 2 = 9 + 12 - 4 = 17
c) 13 + 42 ÷ 3 - 2 x 9 = 13 + 14 - 18 = 9
d) 3 x 7 + 32 ÷ 4 - 2 x 9 = 21 + 8 - 18 = 11
e) 4 x 7 - 2 x 8 + 1 x 9 = 28 - 16 + 9 = 21
f) 8 x 9 - 2 x 27 + 5 x 8 = 72 - 54 + 40 = 58
g) 3 x 7 - 2 x 6 + 4 x 5 = 21 - 12 + 20 = 29
