a) 10-6 + 8 = 12

10 - (6+8) = 10 - 14 = -4

b) 10 - 5 x 6 = 10 - 30 = -20

8 x (7-6) = 8 x 1 = 8

c) 8 x 7 - 6 = 56 - 6 = 50

8 x (7-6) = 8 x 1 = 8

d) 24 : 6 x (-2) = 4 x (-2) = -8

24 : (6 x (-2) = 24 : -12 = -2

e) -12 + 4 : 2 - 8 = -12 + 2 - 8 = -18

(-12 + 4) : 2 - 8 = -8 : 2 - 8 = -4 - 8 = -12

f) 11 - 8 : 4 - 10 = 11 - 2 - 10 = -1

(11 - 8) : (4 - 10) = 3 : -6 = -0,5
