En resumen
A) ( - 4)×[12 + 3×(5 - 8)] = ( - 4)×[15×( - 3)] = ( - 4)×[ - 45] = 180 b) 6×[18 + ( - 4)×(9 - 4)] - 13 = 6×[14×5] - 13 = 6×[70] - 13 = 407 c) 4 - ( - 2)×[ - 8 - 3×(5 - 7)] = 4 - ( - 2)×[ - 11×( - 2)] = 6×22 = 132.

A) ( - 4)×[12 + 3×(5 - 8)] = ( - 4)×[15×( - 3)] = ( - 4)×[ - 45] = 180
b) 6×[18 + ( - 4)×(9 - 4)] - 13 = 6×[14×5] - 13 = 6×[70] - 13 = 407
c) 4 - ( - 2)×[ - 8 - 3×(5 - 7)] = 4 - ( - 2)×[ - 11×( - 2)] = 6×22 = 132.
