Answer 1

a) 17

b) 12 + [35 -8 +2] = 12 + 29 = 41

c) [(18 + 6) : 8 + 15] : 6= (24 : 8 + 15) : 6 = (3 + 15) : 6 = 18 : 6 = 3

d) 37 + [25 - 24] = 37 + 1 = 38

e) 160 : {2 x [7 - 18 : 9]} = 160 : {2 x (7 - 2)} = 160 : {2 x 5} = 160 : 10 = 16

f) 8 + [-5 + (4 + 25)] = 8 + (-5 + 29) = 8 + 24 = 32

g) 63 - [20 + 2 - (5 + 4) +8] = 63 - (30 - 9) = 63 - 21 = 42

h) [1 + (36 - 30)] : (-3) + 1 = (1 + 6) : (-3) + 1 = 7 : (-3) + 1 = -7/3 + 1 = -7/3 + 3/3 = -4/3

i) (76 - 8 x 2) : (10 - 5) = (76 - 16) : 5 = 60 : 5 = 12

j) {[(32 + 3) : 7 + (3 + 3) x 3] x 2 - 12 : 6} x 2 = [(35 : 7 + 9 : 3) x 2 - 2] x 2 = [(5 + 3) x 2 - 2] x 2 = (8 x 2 - 2) x 2 = (16 - 2) x 2 = 14 x 2 = 28
