Answer 1

Odpowiedź:

Szczegółowe wyjaśnienie:

Zad 6

a)

10 - 6 + 8 = 4 + 8 = 12

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

b)

10 - 5 * 6 = 10 - 30 = -20

(10 - 5) * 6 = 5 * 6 = 30

c)

8 * 7 - 6 = 56 - 6 = 50

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

d)

24 : 6 * (-2) = 4 * (-2) = -8

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

e)

-12 + 4 : 2 - 8 = -12 + 2 - 8 = -10 - 8 = -18

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

f)

11 - 8 : 4 - 10 = 11 - 2 - 10 = 9 - 10 = -1

(11 - 8) : (4 - 10) = 3 : (-6) = -0,5 = -5/10 = -1/2
