Se considera numerele: A = 16 + 6 x (6 + 6) - 3 x (3 + 3) ...

Se considera numerele:

A = 16 + 6 x (6 + 6) - 3 x (3 + 3)

B = 136 - 3 x (3 + 27 : 9 x 3)

C = 37 x 5 + (48 : 6 + 14 x 3) : 10

Calculeaza:

2 x ( C - A + B)

Rezolvare

A = 16 + 6 x (6 + 6) - 3 x (3 + 3) = 16 + 6 x 12 - 3 x 6 = 16 + 72 - 18 = 88 - 18 =>

A = 70

B = 136 - 3 x (3 + 27 : 9 x 3) = 136 - 3 x (3 + 3 x 3) = 136 - 3 x (3 + 9) = 136 - 3 x 12 = 136 - 3 x 12 = 136 - 36 => B = 100

C = 37 x 5 + (48 : 6 + 14 x 3) : 10 = 37 x 5 + (8+ 42) : 10 = 37 x 5 + 50 : 10 = 185 + 5 = 190

C = 190

Calculam:

2 x ( C - A + B)

2 x ( 190 - 70 + 100) = 2 x ( 120 + 100) = 2 x 220 = 440
