Răspuns:
A = 16 + 6 x (6 + 6) - 3 (3 + 3)
A= 16 + 6×12-3×6
A= 16+72-18
A= 88-18
A= 70
B = 136 - 3 x (3 + 27:9)
B = 136 - 3× (3+3)
B = 136 - 3×6
B = 136 -18
B = 118
C=37*5+ (48: 6 + 14 x 3): 10
C= 185 + (8+42) : 10
C= 185 + 50:10
C= 185+5
C=190
2 x (C-A + B) = 2(190-70+118)
=2(120+118) = 2× 238
= 476
