2.

a) 4 . 3 + 10 : 2 =

12 + 10 : 2 =

12 + 5 =

17

b) 50 - 16 : 8 + 7 =

50 - 2 + 7 =

48 + 7 =

55

c) 20 - ( 15 + 6 : 3) =

20 - ( 15 + 2) =

20 - 17 =

3

d) (30 + 2 . (5 - 3)) . 2 - 10 =

(30 + 2 . 2) . 2 - 10 =

(30 + 4) . 2 - 10 =

34 . 2 - 10 =

68 - 10 =

58

e) 67 + (50 . (70 : (27 + 8) + 18 : 2) + 21) =

67 + (50 . (70 : 35 + 18 : 2) + 21) =

67 + (50 . (2 + 18 : 2) + 21) =

67 + (50 . (2 + 9) + 21) =

67 + (50 . 11 + 21) =

67 + (550 + 21) =

67 + 571 =

638

f) (10 + (5 . (4 + 2 . 5) - 8) . 2) - 100 =

(10 + (5 . (4 + 10) - 8) . 2) - 100 =

(10 + (5 . 14 - 8) . 2) - 100 =

(10 + (70 - 8) . 2) - 100 =

(10 + 62 . 2) - 100 =

(10 + 124) - 100 =

134 - 100 =

34
