Explicație pas cu pas:
b) 75-3 × {8 x 6 - 26 : (111-110) + 24:12} = 75 - 3 × (48 - 26 : 1 + 2) =
75 - 3 × (48 - 26 + 2) = 75 - 3 × 24 = 75 - 72= 3
c) 14 - 2 × { 16 × ( 15 - 6) : (16 - 8) - 21 : (18 - 11) } : 3 = 14 - 2 × ( 16 × 9 : 8 - 21 : 7 ) : 3 = 14 - 2 × ( 16 × 9 : 8 - 3 ) : 3 = 14 - 2 × ( 144 : 8 - 3 ) : 3 = 14 - 2 × ( 18 - 3 ) : 3 = 14 - 2 × 15 : 3 = 14 - 30 : 3 = 14 - 10 = 4
