Answer 1

Răspuns:

20 - ( 3 × 5 - 2 + 3 ) : ( 26 - 9× 2 ) = 18

20 - ( 15 - 2 + 3 ) : ( 26 - 18 ) =

20 - ( 13 + 3 ) : ( 26 - 18 ) =

20 - 16 : 8 =

20 - 2 = 18

19 + ( 6 × 7 - 18 ) - 2 × 13 = 17

19 + ( 42 - 18 ) - 2 × 13 =

19 + 24 - 2 × 13 =

19 + 24 - 26 =

43 - 26 = 17

48 + ( 103 - 100 ) × 9 + ( 24 : 3 × 0 ) = 75

48 + 3 × 9 + ( 8 × 0 ) =

48 + 3 × 9 + 0 =

48 + 27 + 0 =

75 + 0 = 75
